Taxonomy (biology)
–
Taxonomy is the science of defining groups of biological organisms on the basis of shared characteristics and giving names to those groups. The exact definition of taxonomy varies from source to source, but the core of the remains, the conception, naming. There is some disagreement as to whether biological nomenclature is considered a part of taxonomy, the broadest meaning of taxonomy is used here. The word taxonomy was introduced in 1813 by Candolle, in his Théorie élémentaire de la botanique, the term alpha taxonomy is primarily used today to refer to the discipline of finding, describing, and naming taxa, particularly species. In earlier literature, the term had a different meaning, referring to morphological taxonomy, ideals can, it may be said, never be completely realized. They have, however, a value of acting as permanent stimulants. Some of us please ourselves by thinking we are now groping in a beta taxonomy, turrill thus explicitly excludes from alpha taxonomy various areas of study that he includes within taxonomy as a whole, such as ecology, physiology, genetics, and cytology. He further excludes phylogenetic reconstruction from alpha taxonomy, thus, Ernst Mayr in 1968 defined beta taxonomy as the classification of ranks higher than species. This activity is what the term denotes, it is also referred to as beta taxonomy. How species should be defined in a group of organisms gives rise to practical and theoretical problems that are referred to as the species problem. The scientific work of deciding how to define species has been called microtaxonomy, by extension, macrotaxonomy is the study of groups at higher taxonomic ranks, from subgenus and above only, than species. While some descriptions of taxonomic history attempt to date taxonomy to ancient civilizations, earlier works were primarily descriptive, and focused on plants that were useful in agriculture or medicine. There are a number of stages in scientific thinking. Early taxonomy was based on criteria, the so-called artificial systems. Later came systems based on a complete consideration of the characteristics of taxa, referred to as natural systems, such as those of de Jussieu, de Candolle and Bentham. The publication of Charles Darwins Origin of Species led to new ways of thinking about classification based on evolutionary relationships and this was the concept of phyletic systems, from 1883 onwards. This approach was typified by those of Eichler and Engler, the advent of molecular genetics and statistical methodology allowed the creation of the modern era of phylogenetic systems based on cladistics, rather than morphology alone. Taxonomy has been called the worlds oldest profession, and naming and classifying our surroundings has likely been taking place as long as mankind has been able to communicate

Plant
–
Plants are mainly multicellular, predominantly photosynthetic eukaryotes of the kingdom Plantae. The term is generally limited to the green plants, which form an unranked clade Viridiplantae. This includes the plants, conifers and other gymnosperms, ferns, clubmosses, hornworts, liverworts, mosses and the green algae. Green plants have cell walls containing cellulose and obtain most of their energy from sunlight via photosynthesis by primary chloroplasts and their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic and have lost the ability to produce amounts of chlorophyll or to photosynthesize. Plants are characterized by sexual reproduction and alternation of generations, although reproduction is also common. There are about 300–315 thousand species of plants, of which the great majority, green plants provide most of the worlds molecular oxygen and are the basis of most of Earths ecologies, especially on land. Plants that produce grains, fruits and vegetables form humankinds basic foodstuffs, Plants play many roles in culture. They are used as ornaments and, until recently and in variety, they have served as the source of most medicines. The scientific study of plants is known as botany, a branch of biology, Plants are one of the two groups into which all living things were traditionally divided, the other is animals. The division goes back at least as far as Aristotle, who distinguished between plants, which generally do not move, and animals, which often are mobile to catch their food. Much later, when Linnaeus created the basis of the system of scientific classification. Since then, it has become clear that the plant kingdom as originally defined included several unrelated groups, however, these organisms are still often considered plants, particularly in popular contexts. When the name Plantae or plant is applied to a group of organisms or taxon. The evolutionary history of plants is not yet settled. Those which have been called plants are in bold, the way in which the groups of green algae are combined and named varies considerably between authors. Algae comprise several different groups of organisms which produce energy through photosynthesis, most conspicuous among the algae are the seaweeds, multicellular algae that may roughly resemble land plants, but are classified among the brown, red and green algae. Each of these groups also includes various microscopic and single-celled organisms

Flowering plant
–
The flowering plants, also known as Angiospermae or Magnoliophyta, are the most diverse group of land plants, with 416 families, approx. 13,164 known genera and a total of c.295,383 known species, etymologically, angiosperm means a plant that produces seeds within an enclosure, in other words, a fruiting plant. The term angiosperm comes from the Greek composite word meaning enclosed seeds, the ancestors of flowering plants diverged from gymnosperms in the Triassic Period, during the range 245 to 202 million years ago, and the first flowering plants are known from 160 mya. They diversified extensively during the Lower Cretaceous, became widespread by 120 mya, angiosperms differ from other seed plants in several ways, described in the table. These distinguishing characteristics taken together have made the angiosperms the most diverse and numerous land plants, the amount and complexity of tissue-formation in flowering plants exceeds that of gymnosperms. The vascular bundles of the stem are arranged such that the xylem and phloem form concentric rings, in the dicotyledons, the bundles in the very young stem are arranged in an open ring, separating a central pith from an outer cortex. In each bundle, separating the xylem and phloem, is a layer of meristem or active formative tissue known as cambium, the soft phloem becomes crushed, but the hard wood persists and forms the bulk of the stem and branches of the woody perennial. Among the monocotyledons, the bundles are more numerous in the stem and are scattered through the ground tissue. They contain no cambium and once formed the stem increases in diameter only in exceptional cases, the characteristic feature of angiosperms is the flower. Flowers show remarkable variation in form and elaboration, and provide the most trustworthy external characteristics for establishing relationships among angiosperm species, the function of the flower is to ensure fertilization of the ovule and development of fruit containing seeds. The floral apparatus may arise terminally on a shoot or from the axil of a leaf, occasionally, as in violets, a flower arises singly in the axil of an ordinary foliage-leaf. There are two kinds of cells produced by flowers. Microspores, which divide to become pollen grains, are the male cells and are borne in the stamens. The female cells called megaspores, which divide to become the egg cell, are contained in the ovule. The flower may consist only of parts, as in willow. Usually, other structures are present and serve to protect the sporophylls, the individual members of these surrounding structures are known as sepals and petals. The outer series is usually green and leaf-like, and functions to protect the rest of the flower, the inner series is, in general, white or brightly colored, and is more delicate in structure. It functions to attract insect or bird pollinators, attraction is effected by color, scent, and nectar, which may be secreted in some part of the flower

Eudicots
–
The eudicots, Eudicotidae or eudicotyledons are a monophyletic clade of flowering plants that had been called tricolpates or non-magnoliid dicots by previous authors. The close relationships among flowering plants with tricolpate pollen grains was initially seen in studies of shared derived characters. These plants have a trait in their pollen grains of exhibiting three colpi or grooves paralleling the polar axis. Later molecular evidence confirmed the basis for the evolutionary relationships among flowering plants with tricolpate pollen grains. The term means true dicotyledons, as it contains the majority of plants that have been considered dicots and have characteristics of the dicots, the term eudicots has subsequently been widely adopted in botany to refer to one of the two largest clades of angiosperms, monocots being the other. The remaining angiosperms are sometimes referred to as basal angiosperms or paleodicots, the other name for the eudicots is tricolpates, a name which refers to the grooved structure of the pollen. Members of the group have tricolpate pollen, or forms derived from it and these pollens have three or more pores set in furrows called colpi. In contrast, most of the seed plants produce monosulcate pollen. The name tricolpates is preferred by some botanists to avoid confusion with the dicots, numerous familiar plants are eudicots, including many common food plants, trees, and ornamentals. Most leafy trees of midlatitudes also belong to eudicots, with exceptions being magnolias and tulip trees which belong to magnoliids, and Ginkgo biloba. The name eudicots is used in the APG system, of 1998 and it is applied to a clade, a monophyletic group, which includes most of the dicots. The eudicots can be divided into two groups, the basal eudicots and the core eudicots, basal eudicot is an informal name for a paraphyletic group. The core eudicots are a monophyletic group, a 2010 study suggested the core eudicots can be divided into two clades, Gunnerales and a clade called Pentapetalae, comprising all the remaining core eudicots
5.
Asterids
–
In the APG IV system for the classification of flowering plants, the name asterids denotes a clade. Most of the taxa belonging to this clade had been referred to the Asteridae in the Cronquist system, the name asterids resembles the earlier botanical name but is intended to be the name of a clade rather than a formal ranked name, in the sense of the ICBN. The phylogenetic tree presented hereafter has been proposed by the APG IV project, genetic analysis carried out after APG II maintains that the sister to all other asterids are the Cornales. A second order that split from the base of the asterids are the Ericales, the remaining orders cluster into two clades, the lamiids and the campanulids. The structure of both of these clades has changed in APG III, in APG III system, the following clades were renamed, euasterids I → lamiids euasterids II → campanulids Asterids in Stevens, P. F.

Lamiales
–
The Lamiales are an order in the asterid group of dicotyledonous flowering plants. It includes about 24,000 species divided into about 20 families, in the classification system of Dahlgren the Lamiales were in the superorder Lamiiflorae. Lamiales has become the name for this much larger combined group. The placement of the Boraginaceae is unclear, but phylogenetic work shows this family does not belong in Lamiales, Lamiales A parsimony analysis of the Asteridae sensu lato based on rbcL sequences Disintegration of the Scrophulariaceae L.

Sesamum
–
Sesamum is a genus of approximately 20 species in the flowering plant family Pedaliaceae. The plants are annual or perennial herbs with edible seeds, the best-known member of the genus is sesame, Sesamum indicum, the source of sesame seeds. The species are primarily African, with species occurring in India, Sri Lanka. The origin of S. indicum is uncertain as it is cultivated and naturalized in tropical regions. The genus is related to the strictly African genus Ceratotheca and is itself probably African in origin. Sesamum indicum L. Sesamum lamiifolium Engl, Sesamum latifolium J. B.

Binomial nomenclature
–
Such a name is called a binomial name, a binomen, binominal name or a scientific name, more informally it is also called a Latin name. The first part of the name identifies the genus to which the species belongs, for example, humans belong to the genus Homo and within this genus to the species Homo sapiens. The formal introduction of system of naming species is credited to Carl Linnaeus. But Gaspard Bauhin, in as early as 1623, had introduced in his book Pinax theatri botanici many names of genera that were adopted by Linnaeus. Although the general principles underlying binomial nomenclature are common to these two codes, there are differences, both in the terminology they use and in their precise rules. Similarly, both parts are italicized when a binomial name occurs in normal text, thus the binomial name of the annual phlox is now written as Phlox drummondii. In scientific works, the authority for a name is usually given, at least when it is first mentioned. In zoology Patella vulgata Linnaeus,1758, the original name given by Linnaeus was Fringilla domestica, the parentheses indicate that the species is now considered to belong in a different genus. The ICZN does not require that the name of the person who changed the genus be given, nor the date on which the change was made, in botany Amaranthus retroflexus L. – L. is the standard abbreviation used in botany for Linnaeus. – Linnaeus first named this bluebell species Scilla italica, Rothmaler transferred it to the genus Hyacinthoides, the ICN does not require that the dates of either publication be specified. Prior to the adoption of the binomial system of naming species. Together they formed a system of polynomial nomenclature and these names had two separate functions. First, to designate or label the species, and second, to be a diagnosis or description, such polynomial names may sometimes look like binomials, but are significantly different. For example, Gerards herbal describes various kinds of spiderwort, The first is called Phalangium ramosum, Branched Spiderwort, is aptly termed Phalangium Ephemerum Virginianum, Soon-Fading Spiderwort of Virginia. The Latin phrases are short descriptions, rather than identifying labels, the Bauhins, in particular Caspar Bauhin, took some important steps towards the binomial system, by pruning the Latin descriptions, in many cases to two words. The adoption by biologists of a system of binomial nomenclature is due to Swedish botanist and physician Carl von Linné. It was in his 1753 Species Plantarum that he first began using a one-word trivial name together with a generic name in a system of binomial nomenclature. This trivial name is what is now known as an epithet or specific name

Carl Linnaeus
–
Carl Linnaeus, also known after his ennoblement as Carl von Linné, was a Swedish botanist, physician, and zoologist, who formalised the modern system of naming organisms called binomial nomenclature. He is known by the father of modern taxonomy. Many of his writings were in Latin, and his name is rendered in Latin as Carolus Linnæus, Linnaeus was born in the countryside of Småland, in southern Sweden. He received most of his education at Uppsala University. He lived abroad between 1735 and 1738, where he studied and also published a first edition of his Systema Naturae in the Netherlands and he then returned to Sweden, where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on journeys through Sweden to find and classify plants. In the 1750s and 1760s, he continued to collect and classify animals, plants, and minerals, at the time of his death, he was one of the most acclaimed scientists in Europe. The philosopher Jean-Jacques Rousseau sent him the message, Tell him I know no man on earth. The German writer Johann Wolfgang von Goethe wrote, With the exception of Shakespeare and Spinoza, Swedish author August Strindberg wrote, Linnaeus was in reality a poet who happened to become a naturalist. Among other compliments, Linnaeus has been called Princeps botanicorum, The Pliny of the North and he is also considered as one of the founders of modern ecology. In botany, the abbreviation used to indicate Linnaeus as the authority for species names is L. In older publications, sometimes the abbreviation Linn. is found, Linnæus was born in the village of Råshult in Småland, Sweden, on 23 May 1707. He was the first child of Nicolaus Ingemarsson and Christina Brodersonia and his siblings were Anna Maria Linnæa, Sofia Juliana Linnæa, Samuel Linnæus, and Emerentia Linnæa. One of a line of peasants and priests, Nils was an amateur botanist, a Lutheran minister. Christina was the daughter of the rector of Stenbrohult, Samuel Brodersonius, a year after Linnæus birth, his grandfather Samuel Brodersonius died, and his father Nils became the rector of Stenbrohult. The family moved into the rectory from the curates house, even in his early years, Linnæus seemed to have a liking for plants, flowers in particular. Whenever he was upset, he was given a flower, which calmed him. Nils spent much time in his garden and often showed flowers to Linnaeus, soon Linnæus was given his own patch of earth where he could grow plants

Synonym (taxonomy)
–
For example, Linnaeus was the first to give a scientific name to the Norway spruce, which he called Pinus abies. This name is no longer in use, it is now a synonym of the current scientific name which is Picea abies, unlike synonyms in other contexts, in taxonomy a synonym is not interchangeable with the name of which it is a synonym. In taxonomy, synonyms are not equals, but have a different status, for any taxon with a particular circumscription, position, and rank, only one scientific name is considered to be the correct one at any given time. A synonym cannot exist in isolation, it is always an alternative to a different scientific name, given that the correct name of a taxon depends on the taxonomic viewpoint used a name that is one taxonomists synonym may be another taxonomists correct name. Synonyms may arise whenever the same taxon is described and named more than once, independently. They may also arise when existing taxa are changed, as when two taxa are joined to one, a species is moved to a different genus. To the general user of scientific names, in such as agriculture, horticulture, ecology, general science. A synonym is a name that was used as the correct scientific name but which has been displaced by another scientific name. Thus Oxford Dictionaries Online defines the term as a name which has the same application as another. In handbooks and general texts, it is useful to have mentioned as such after the current scientific name. Synonyms used in this way may not always meet the strict definitions of the synonym in the formal rules of nomenclature which govern scientific names. Changes of scientific name have two causes, they may be taxonomic or nomenclatural, a name change may be caused by changes in the circumscription, position or rank of a taxon, representing a change in taxonomic, scientific insight. A name change may be due to purely nomenclatural reasons, that is, based on the rules of nomenclature, the earliest such name is called the senior synonym, while the later name is the junior synonym. One basic principle of zoological nomenclature is that the earliest correctly published name, synonyms are important because if the earliest name cannot be used, then the next available junior synonym must be used for the taxon. Objective synonyms refer to taxa with the type and same rank. For example, John Edward Gray published the name Antilocapra anteflexa in 1855 for a species of pronghorn, however, it is now commonly accepted that his specimen was an unusual individual of the species Antilocapra americana published by George Ord in 1815. Ords name thus takes precedence, with Antilocapra anteflexa being a subjective synonym. Objective synonyms are common at the level of genera, because for various reasons two genera may contain the type species, these are objective synonyms

Tonne
–
The SI symbol for the tonne is t, adopted at the same time as the unit itself in 1879. Its use is also official, for the metric ton, within the United States, having been adopted by the US National Institute of Standards and it is a symbol, not an abbreviation, and should not be followed by a period. Informal and non-approved symbols or abbreviations include T, mT, MT, in French and all English-speaking countries that are predominantly metric, tonne is the correct spelling. Before metrication in the UK the unit used for most purposes was the Imperial ton of 2,240 pounds avoirdupois, equivalent to 1,016 kg, differing by just 1. 6% from the tonne. Ton and tonne are both derived from a Germanic word in use in the North Sea area since the Middle Ages to designate a large cask. A full tun, standing about a high, could easily weigh a tonne. An English tun of wine weighs roughly a tonne,954 kg if full of water, in the United States, the unit was originally referred to using the French words millier or tonneau, but these terms are now obsolete. The Imperial and US customary units comparable to the tonne are both spelled ton in English, though they differ in mass, one tonne is equivalent to, Metric/SI,1 megagram. Equal to 1000000 grams or 1000 kilograms, megagram, Mg, is the official SI unit. Mg is distinct from mg, milligram, pounds, Exactly 1000/0. 453 592 37 lb, or approximately 2204.622622 lb. US/Short tons, Exactly 1/0. 907 184 74 short tons, or approximately 1.102311311 ST. One short ton is exactly 0.90718474 t, imperial/Long tons, Exactly 1/1. 016 046 9088 long tons, or approximately 0.9842065276 LT. One long ton is exactly 1.0160469088 t, for multiples of the tonne, it is more usual to speak of thousands or millions of tonnes. Kilotonne, megatonne, and gigatonne are more used for the energy of nuclear explosions and other events. When used in context, there is little need to distinguish between metric and other tons, and the unit is spelt either as ton or tonne with the relevant prefix attached. *The equivalent units columns use the short scale large-number naming system used in most English-language countries. †Values in the equivalent short and long tons columns are rounded to five significant figures, ǂThough non-standard, the symbol kt is also sometimes used for knot, a unit of speed for sea-going vessels, and should not be confused with kilotonne. A metric ton unit can mean 10 kilograms within metal trading and it traditionally referred to a metric ton of ore containing 1% of metal. In the case of uranium, the acronym MTU is sometimes considered to be metric ton of uranium, in the petroleum industry the tonne of oil equivalent is a unit of energy, the amount of energy released by burning one tonne of crude oil, approximately 42 GJ

Sub-Saharan Africa
–
Sub-Saharan Africa is, geographically, the area of the continent of Africa that lies south of the Sahara. According to the UN, it consists of all African countries that are fully or partially located south of the Sahara and it contrasts with North Africa, whose territories are part of the League of Arab states within the Arab world. Somalia, Djibouti, Comoros and Mauritania are geographically in Sub-Saharan Africa, the Sahel is the transitional zone between the Sahara and the tropical savanna and forest-savanna mosaic to the south. The Sahara pump theory explains how flora and fauna left Africa to penetrate the Middle East, African pluvial periods are associated with a wet Sahara phase during which larger lakes and more rivers existed. Geographers historically divided the region into several distinct ethnographic sections based on each areas respective inhabitants, commentators in Arabic in the medieval period used the general term bilâd as-sûdân for the vast Sudan region, or sometimes extending from the coast of West Africa to Western Sudan. Its equivalent in Southeast Africa was Zanj, which was situated in the vicinity of the Great Lakes region. The geographers drew an explicit distinction between the Sudan region and its analogue Zanj, from the area to their extreme east on the Red Sea coast in the Horn of Africa. In modern-day Ethiopia and Eritrea was Al-Habash or Abyssinia, which was inhabited by the Habash or Abyssinians, Sub-Saharan Africa has a wide variety of climate zones or biomes. South Africa and the Democratic Republic of the Congo in particular are considered Megadiverse countries, the Sahel shoots across all of Africa at a latitude of about 10° to 15° N. Countries that include parts of the Sahara Desert proper in their territories and parts of the Sahel in their southern region include Mauritania, Mali, Niger, Chad. The Sahel has a hot semi-arid climate, South of the Sahel, there is a belt of savanna, widening to include most of South Sudan and Ethiopia in the east. The Serengeti ecosystem is located in northwestern Tanzania and extends to southwestern Kenya, the Kalahari Basin includes the Kalahari Desert surrounded by a belt of semi-desert. The Bushveld is a tropical ecoregion of Southern Africa. The Karoo is a semi-desert in western South Africa and this occurred 10 million to 5 million years ago. By 3 million years ago several australopithecine hominid species had developed throughout southern, eastern and they were tool users rather than tool manufacturers. The tools were classed as Oldowan, roughly 1.8 million years ago, Homo ergaster first appeared in the fossil record in Africa. From Homo ergaster, Homo erectus evolved 1.5 million years ago, some of the earlier representatives of this species were small-brained and used primitive stone tools, much like H. habilis. The brain later grew in size, and H. erectus eventually developed a complex stone tool technology called the Acheulean

Nepal
–
Nepal, officially the Federal Democratic Republic of Nepal, is a landlocked central Himalayan country in South Asia. Nepal is divided into 7 provinces and 75 districts and 744 local units including 4 metropolises,13 sub-metropolises,246 municipal councils and 481 village and it has a population of 26.4 million and is the 93rd largest country by area. Bordering China in the north and India in the south, east, Nepal does not border Bangladesh, which is located within only 27 km of its southeastern tip. It neither borders Bhutan due to the Indian state of Sikkim being located in between, Nepal has a diverse geography, including fertile plains, subalpine forested hills, and eight of the worlds ten tallest mountains, including Mount Everest, the highest point on Earth. Kathmandu is the capital and largest city. It is a nation with Nepali as the official language. The territory of Nepal has a history since the Neolithic age. The name Nepal is first recorded in texts from the Vedic Age, the era which founded Hinduism, in the middle of the first millennium BCE, Gautama Buddha, the founder of Buddhism, was born in southern Nepal. Parts of northern Nepal were intertwined with the culture of Tibet, the Kathmandu Valley in central Nepal became known as Nepal proper because of its complex urban civilization. It was the seat of the prosperous Newar confederacy known as Nepal Mandala, the Himalayan branch of the ancient Silk Road was dominated by the valleys traders. The cosmopolitan region developed distinct traditional art and architecture, by the 18th century, the Gorkha Kingdom achieved the unification of Nepal. The Shah dynasty established the Kingdom of Nepal and later formed an alliance with the British Empire, the country was never colonized but served as a buffer state between Imperial China and Colonial India. In the 20th century, Nepal ended its isolation and forged ties with regional powers. Parliamentary democracy was introduced in 1951, but was suspended by Nepalese monarchs in 1960 and 2005. The Nepalese Civil War resulted in the proclamation of a republic in 2008, modern Nepal is a federal secular parliamentary republic. Nepal is a nation, ranking 144th on the Human Development Index in 2016. The country struggles with the transition from a monarchy to a republic and it also suffers from high levels of hunger and poverty. Despite these challenges, Nepal is making progress, with the government declaring its commitment to elevate the nation from least developed country status by 2022

Latin
–
Latin is a classical language belonging to the Italic branch of the Indo-European languages. The Latin alphabet is derived from the Etruscan and Greek alphabets, Latin was originally spoken in Latium, in the Italian Peninsula. Through the power of the Roman Republic, it became the dominant language, Vulgar Latin developed into the Romance languages, such as Italian, Portuguese, Spanish, French, and Romanian. Latin, Italian and French have contributed many words to the English language, Latin and Ancient Greek roots are used in theology, biology, and medicine. By the late Roman Republic, Old Latin had been standardised into Classical Latin, Vulgar Latin was the colloquial form spoken during the same time and attested in inscriptions and the works of comic playwrights like Plautus and Terence. Late Latin is the language from the 3rd century. Later, Early Modern Latin and Modern Latin evolved, Latin was used as the language of international communication, scholarship, and science until well into the 18th century, when it began to be supplanted by vernaculars. Ecclesiastical Latin remains the language of the Holy See and the Roman Rite of the Catholic Church. Today, many students, scholars and members of the Catholic clergy speak Latin fluently and it is taught in primary, secondary and postsecondary educational institutions around the world. The language has been passed down through various forms, some inscriptions have been published in an internationally agreed, monumental, multivolume series, the Corpus Inscriptionum Latinarum. Authors and publishers vary, but the format is about the same, volumes detailing inscriptions with a critical apparatus stating the provenance, the reading and interpretation of these inscriptions is the subject matter of the field of epigraphy. The works of several hundred ancient authors who wrote in Latin have survived in whole or in part and they are in part the subject matter of the field of classics. The Cat in the Hat, and a book of fairy tales, additional resources include phrasebooks and resources for rendering everyday phrases and concepts into Latin, such as Meissners Latin Phrasebook. The Latin influence in English has been significant at all stages of its insular development. From the 16th to the 18th centuries, English writers cobbled together huge numbers of new words from Latin and Greek words, dubbed inkhorn terms, as if they had spilled from a pot of ink. Many of these words were used once by the author and then forgotten, many of the most common polysyllabic English words are of Latin origin through the medium of Old French. Romance words make respectively 59%, 20% and 14% of English, German and those figures can rise dramatically when only non-compound and non-derived words are included. Accordingly, Romance words make roughly 35% of the vocabulary of Dutch, Roman engineering had the same effect on scientific terminology as a whole

Greek language
–
Greek is an independent branch of the Indo-European family of languages, native to Greece and other parts of the Eastern Mediterranean. It has the longest documented history of any living language, spanning 34 centuries of written records and its writing system has been the Greek alphabet for the major part of its history, other systems, such as Linear B and the Cypriot syllabary, were used previously. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic and many other writing systems. Together with the Latin texts and traditions of the Roman world, during antiquity, Greek was a widely spoken lingua franca in the Mediterranean world and many places beyond. It would eventually become the official parlance of the Byzantine Empire, the language is spoken by at least 13.2 million people today in Greece, Cyprus, Italy, Albania, Turkey, and the Greek diaspora. Greek roots are used to coin new words for other languages, Greek. Greek has been spoken in the Balkan peninsula since around the 3rd millennium BC, the earliest written evidence is a Linear B clay tablet found in Messenia that dates to between 1450 and 1350 BC, making Greek the worlds oldest recorded living language. Among the Indo-European languages, its date of earliest written attestation is matched only by the now extinct Anatolian languages, the Greek language is conventionally divided into the following periods, Proto-Greek, the unrecorded but assumed last ancestor of all known varieties of Greek. The unity of Proto-Greek would have ended as Hellenic migrants entered the Greek peninsula sometime in the Neolithic era or the Bronze Age, Mycenaean Greek, the language of the Mycenaean civilisation. It is recorded in the Linear B script on tablets dating from the 15th century BC onwards, Ancient Greek, in its various dialects, the language of the Archaic and Classical periods of the ancient Greek civilisation. It was widely known throughout the Roman Empire, after the Roman conquest of Greece, an unofficial bilingualism of Greek and Latin was established in the city of Rome and Koine Greek became a first or second language in the Roman Empire. The origin of Christianity can also be traced through Koine Greek, Medieval Greek, also known as Byzantine Greek, the continuation of Koine Greek in Byzantine Greece, up to the demise of the Byzantine Empire in the 15th century. Much of the written Greek that was used as the language of the Byzantine Empire was an eclectic middle-ground variety based on the tradition of written Koine. Modern Greek, Stemming from Medieval Greek, Modern Greek usages can be traced in the Byzantine period and it is the language used by the modern Greeks, and, apart from Standard Modern Greek, there are several dialects of it. In the modern era, the Greek language entered a state of diglossia, the historical unity and continuing identity between the various stages of the Greek language is often emphasised. Greek speakers today still tend to regard literary works of ancient Greek as part of their own rather than a foreign language and it is also often stated that the historical changes have been relatively slight compared with some other languages. According to one estimation, Homeric Greek is probably closer to demotic than 12-century Middle English is to modern spoken English, Greek is spoken by about 13 million people, mainly in Greece, Albania and Cyprus, but also worldwide by the large Greek diaspora. Greek is the language of Greece, where it is spoken by almost the entire population

Arabic
–
Arabic is a Central Semitic language that was first spoken in Iron Age northwestern Arabia and is now the lingua franca of the Arab world. Arabic is also the language of 1.7 billion Muslims. It is one of six languages of the United Nations. The modern written language is derived from the language of the Quran and it is widely taught in schools and universities, and is used to varying degrees in workplaces, government, and the media. The two formal varieties are grouped together as Literary Arabic, which is the language of 26 states. Modern Standard Arabic largely follows the standards of Quranic Arabic. Much of the new vocabulary is used to denote concepts that have arisen in the post-Quranic era, Arabic has influenced many languages around the globe throughout its history. During the Middle Ages, Literary Arabic was a vehicle of culture in Europe, especially in science, mathematics. As a result, many European languages have borrowed many words from it. Many words of Arabic origin are found in ancient languages like Latin. Balkan languages, including Greek, have acquired a significant number of Arabic words through contact with Ottoman Turkish. Arabic has also borrowed words from languages including Greek and Persian in medieval times. Arabic is a Central Semitic language, closely related to the Northwest Semitic languages, the Ancient South Arabian languages, the Semitic languages changed a great deal between Proto-Semitic and the establishment of the Central Semitic languages, particularly in grammar. Innovations of the Central Semitic languages—all maintained in Arabic—include, The conversion of the suffix-conjugated stative formation into a past tense, the conversion of the prefix-conjugated preterite-tense formation into a present tense. The elimination of other prefix-conjugated mood/aspect forms in favor of new moods formed by endings attached to the prefix-conjugation forms, the development of an internal passive. These features are evidence of descent from a hypothetical ancestor. In the southwest, various Central Semitic languages both belonging to and outside of the Ancient South Arabian family were spoken and it is also believed that the ancestors of the Modern South Arabian languages were also spoken in southern Arabia at this time. To the north, in the oases of northern Hijaz, Dadanitic and Taymanitic held some prestige as inscriptional languages, in Najd and parts of western Arabia, a language known to scholars as Thamudic C is attested

Africa
–
Africa is the worlds second-largest and second-most-populous continent. At about 30.3 million km² including adjacent islands, it covers 6% of Earths total surface area and 20.4 % of its land area. With 1.2 billion people as of 2016, it accounts for about 16% of the human population. The continent includes Madagascar and various archipelagos and it contains 54 fully recognized sovereign states, nine territories and two de facto independent states with limited or no recognition. Africas population is the youngest amongst all the continents, the age in 2012 was 19.7. Algeria is Africas largest country by area, and Nigeria by population, afarensis, Homo erectus, H. habilis and H. ergaster – with the earliest Homo sapiens found in Ethiopia being dated to circa 200,000 years ago. Africa straddles the equator and encompasses numerous climate areas, it is the continent to stretch from the northern temperate to southern temperate zones. Africa hosts a diversity of ethnicities, cultures and languages. In the late 19th century European countries colonized most of Africa, Africa also varies greatly with regard to environments, economics, historical ties and government systems. However, most present states in Africa originate from a process of decolonization in the 20th century, afri was a Latin name used to refer to the inhabitants of Africa, which in its widest sense referred to all lands south of the Mediterranean. This name seems to have referred to a native Libyan tribe. The name is connected with Hebrew or Phoenician ʿafar dust. The same word may be found in the name of the Banu Ifran from Algeria and Tripolitania, under Roman rule, Carthage became the capital of the province of Africa Proconsularis, which also included the coastal part of modern Libya. The Latin suffix -ica can sometimes be used to denote a land, the later Muslim kingdom of Ifriqiya, modern-day Tunisia, also preserved a form of the name. According to the Romans, Africa lay to the west of Egypt, while Asia was used to refer to Anatolia, as Europeans came to understand the real extent of the continent, the idea of Africa expanded with their knowledge. 25,4, whose descendants, he claimed, had invaded Libya, isidore of Seville in Etymologiae XIV.5.2. Suggests Africa comes from the Latin aprica, meaning sunny, massey, in 1881, stated that Africa is derived from the Egyptian af-rui-ka, meaning to turn toward the opening of the Ka. The Ka is the double of every person and the opening of the Ka refers to a womb or birthplace

Ptolemaic Kingdom
–
The Ptolemaic Kingdom was a Hellenistic kingdom based in Egypt. Alexandria became the city and a major center of Greek culture. To gain recognition by the native Egyptian populace, they named themselves the successors to the Pharaohs, the later Ptolemies took on Egyptian traditions by marrying their siblings, had themselves portrayed on public monuments in Egyptian style and dress, and participated in Egyptian religious life. The Ptolemies had to fight native rebellions and were involved in foreign and civil wars led to the decline of the kingdom. Hellenistic culture continued to thrive in Egypt throughout the Roman and Byzantine periods until the Muslim conquest. The era of Ptolemaic reign in Egypt is one of the most well documented periods of the Hellenistic Era. In 332 BC, Alexander the Great, King of Macedon invaded the Achaemenid satrapy of Egypt and he visited Memphis, and traveled to the oracle of Amun at the Oasis of Siwa. The oracle declared him to be the son of Amun, the wealth of Egypt could now be harnessed for Alexanders conquest of the rest of the Persian Empire. Early in 331 BC he was ready to depart, and led his forces away to Phoenicia and he left Cleomenes as the ruling nomarch to control Egypt in his absence. Following Alexanders death in Babylon in 323 BC, a crisis erupted among his generals. Perdiccas appointed Ptolemy, one of Alexanders closest companions, to be satrap of Egypt, Ptolemy ruled Egypt from 323 BC, nominally in the name of the joint kings Philip III and Alexander IV. However, as Alexander the Greats empire disintegrated, Ptolemy soon established himself as ruler in his own right, Ptolemy successfully defended Egypt against an invasion by Perdiccas in 321 BC, and consolidated his position in Egypt and the surrounding areas during the Wars of the Diadochi. In 305 BC, Ptolemy took the title of King, as Ptolemy I Soter, he founded the Ptolemaic dynasty that was to rule Egypt for nearly 300 years. All the male rulers of the dynasty took the name Ptolemy, while princesses and queens preferred the names Cleopatra, Arsinoe and Berenice. Because the Ptolemaic kings adopted the Egyptian custom of marrying their sisters, many of the kings ruled jointly with their spouses and this custom made Ptolemaic politics confusingly incestuous, and the later Ptolemies were increasingly feeble. The only Ptolemaic Queens to officially rule on their own were Berenice III, Cleopatra V did co-rule, but it was with another female, Berenice IV. Cleopatra VII officially co-ruled with Ptolemy XIII Theos Philopator, Ptolemy XIV, and Ptolemy XV, upper Egypt, farthest from the centre of government, was less immediately affected, even though Ptolemy I established the Greek colony of Ptolemais Hermiou to be its capital. But within a century Greek influence had spread through the country, nevertheless, the Greeks always remained a privileged minority in Ptolemaic Egypt

New Kingdom of Egypt
–
Radiocarbon dating places the exact beginning of the New Kingdom between 1570–1544 BC. The New Kingdom followed the Second Intermediate Period and was succeeded by the Third Intermediate Period and it was Egypt’s most prosperous time and marked the peak of its power. The later part of period, under the Nineteenth and Twentieth Dynasties is also known as the Ramesside period. It is named after the pharaohs that took the name of Ramesses I. Egyptian armies fought Hittite armies for control of modern-day Syria, the Eighteenth Dynasty contained some of Egypts most famous Pharaohs, including Ahmose I, Hatshepsut, Thutmose III, Amenhotep III, Akhenaten and Tutankhamun. Queen Hatshepsut concentrated on expanding Egypts external trade by sending an expedition to the land of Punt. Thutmose III expanded Egypts army and wielded it with success to consolidate the empire created by his predecessors. This resulted in a peak in Egypts power and wealth during the reign of Amenhotep III, during the reign of Thutmose III, Pharaoh, originally referring to the kings palace, became a form of address for the person who was king. Akhenatens religious fervor is cited as the reason why he was written out of Egyptian history. Under his reign, in the 14th century BC, Egyptian art flourished and attained a level of realism. Towards the end of the 18th Dynasty, the situation had changed radically, Ramesses II sought to recover territories in the Levant that had been held by the 18th Dynasty. His campaigns of reconquest culminated in the Battle of Kadesh, where he led Egyptian armies against those of the Hittite king Muwatalli II. Ramesses was caught in historys first recorded military ambush, although he was able to rally his troops, the outcome of the battle was undecided with both sides claiming victory at their home front, ultimately resulting in a peace treaty between the two nations. The last great pharaoh from the New Kingdom is widely considered to be Ramesses III, in the eighth year of his reign the Sea Peoples invaded Egypt by land and sea. Ramesses III defeated them in two great land and sea battles and he incorporated them as subject peoples and settled them in Southern Canaan although there is evidence that they forced their way into Canaan. Their presence in Canaan may have contributed to the formation of new states, such as Philistia and he was also compelled to fight invading Libyan tribesmen in two major campaigns in Egypts Western Delta in his sixth year and eleventh year respectively. The heavy cost of this warfare slowly drained Egypts treasury and contributed to the decline of the Egyptian Empire in Asia. Something in the air prevented much sunlight from reaching the ground, one proposed cause is the Hekla 3 eruption of the Hekla volcano in Iceland but the dating of this remains disputed

Babylon
–
Babylon was a major city of ancient Mesopotamia in the fertile plain between the Tigris and Euphrates rivers. The city was built upon the Euphrates and divided in parts along its left and right banks. Babylon was originally a small Semitic Akkadian city dating from the period of the Akkadian Empire c.2300 BC, the town attained independence as part of a small city-state with the rise of the First Amorite Babylonian Dynasty in 1894 BC. Babylon grew and South Mesopotamia came to be known as Babylonia, the empire quickly dissolved after Hammurabis death and Babylon spent long periods under Assyrian, Kassite and Elamite domination. After being destroyed and then rebuilt by the Assyrians, Babylon became the capital of the Neo-Babylonian Empire from 609 to 539 BC, the Hanging Gardens of Babylon was one of the Seven Wonders of the Ancient World. After the fall of the Neo-Babylonian Empire, the city came under the rule of the Achaemenid, Seleucid, Parthian, Roman, and Sassanid empires. It has been estimated that Babylon was the largest city in the world from c.1770 to 1670 BC and it was perhaps the first city to reach a population above 200,000. Estimates for the extent of its area range from 890 to 900 hectares. The remains of the city are in present-day Hillah, Babil Governorate, Iraq, about 85 kilometres south of Baghdad, comprising a large tell of broken mud-brick buildings, the English Babylon comes from Greek Babylṓn, a transliteration of the Akkadian Babili. The Babylonian name in the early 2nd millennium BC had been Babilli or Babilla, by the 1st millennium BC, it had changed to Babili under the influence of the folk etymology which traced it to bāb-ili. The Gate of God or Gate of El being from the Aramaic Hebrew Bab for Gate and El for God and this being similar to the Hebrew word for confusion Balal. In the Bible, the name appears as Babel, interpreted in the Hebrew Scriptures Book of Genesis to mean confusion, the modern English verb, to babble, or to speak meaningless words, is popularly thought to derive from this name, but there is no direct connection. The remains of the city are in present-day Hillah, Babil Governorate, Iraq, about 85 kilometers south of Baghdad, comprising a large tell of broken mud-brick buildings and debris. The site at Babylon consists of a number of mounds covering an area of about 2 by 1 kilometer, oriented north to south, along the Euphrates to the west. Originally, the river roughly bisected the city, but the course of the river has since shifted so that most of the remains of the western part of the city are now inundated. Some portions of the city wall to the west of the river also remain, remains of the city include, Kasr—also called Palace or Castle, it is the location of the Neo-Babylonian ziggurat Etemenanki and lies in the center of the site. Amran Ibn Ali—the highest of the mounds at 25 meters, to the south and it is the site of Esagila, a temple of Marduk which also contained shrines to Ea and Nabu. Homera—a reddish colored mound on the west side, most of the Hellenistic remains are here

Assyria
–
Assyria was a major Mesopotamian East Semitic-speaking kingdom and empire of the ancient Near East and the Levant. Centered on the Tigris in Upper Mesopotamia, the Assyrians came to rule powerful empires at several times. Assyria is named after its capital, the ancient city of Aššur. In the 25th and 24th centuries BC, Assyrian kings were pastoral leaders, Assyria can also refer to the geographic region or heartland where Assyria, its empires and the Assyrian people were centered. The indigenous modern Eastern Aramaic-speaking Assyrian Christian ethnic minority in northern Iraq, north east Syria, southeast Turkey, in prehistoric times, the region that was to become known as Assyria was home to a Neanderthal culture such as has been found at the Shanidar Cave. The earliest Neolithic sites in Assyria were the Jarmo culture c.7100 BC and Tell Hassuna, during the 3rd millennium BC, a very intimate cultural symbiosis developed between the Sumerians and the Akkadians throughout Mesopotamia, which included widespread bilingualism. The influence of Sumerian on Akkadian, and vice versa, is evident in all areas, from lexical borrowing on a scale, to syntactic, morphological. This has prompted scholars to refer to Sumerian and Akkadian in the third millennium BC as a sprachbund and it is highly likely that the city was named in honour of its patron Assyrian god with the same name. The city of Aššur, together with a number of other Assyrian cities, however it is likely that they were initially Sumerian-dominated administrative centres. In the late 26th century BC, Eannatum of Lagash, then the dominant Sumerian ruler in Mesopotamia, similarly, in c. the early 25th century BC, Lugal-Anne-Mundu the king of the Sumerian state of Adab lists Subartu as paying tribute to him. Of the early history of the kingdom of Assyria, little is known, in the Assyrian King List, the earliest king recorded was Tudiya. According to Georges Roux he would have lived in the mid 25th century BC, Tudiya was succeeded on the list by Adamu, the first known reference to the Semitic name Adam and then a further thirteen rulers. The earliest kings, such as Tudiya, who are recorded as kings who lived in tents, were independent semi-nomadic pastoralist rulers and these kings at some point became fully urbanised and founded the city state of Ashur in the mid 21st century BC. During the Akkadian Empire, the Assyrians, like all the Mesopotamian Semites, became subject to the dynasty of the city state of Akkad, the Akkadian Empire founded by Sargon the Great claimed to encompass the surrounding four quarters. Assyrian rulers were subject to Sargon and his successors, and the city of Ashur became an administrative center of the Empire. On those tablets, Assyrian traders in Burushanda implored the help of their ruler, Sargon the Great, the name Hatti itself even appears in later accounts of his grandson, Naram-Sin, campaigning in Anatolia. Assyrian and Akkadian traders spread the use of writing in the form of the Mesopotamian cuneiform script to Asia Minor, the Akkadian Empire was destroyed by economic decline and internal civil war, followed by attacks from barbarian Gutian people in 2154 BC. The rulers of Assyria during the period between c.2154 BC and 2112 BC once again fully independent, as the Gutians are only known to have administered southern Mesopotamia

Urartu
–
Urartu, also known as Kingdom of Van, was an Iron Age kingdom centred on Lake Van in the Armenian Highlands. It corresponds to the biblical Kingdom of Ararat, the language appears in cuneiform inscriptions. It is argued on linguistic evidence that came in contact with Urartian at an early date. That a distinction should be made between the geographical and the entity was already pointed out by König. The landscape corresponds to the plateau between Anatolia, Mesopotamia, the Iranian Plateau, and the Caucasus Mountains, later known as the Armenian Highlands. The kingdom rose to power in the mid-ninth century BC, the heirs of Urartu are the Armenians and their successive kingdoms. The name Urartu comes from Assyrian sources, Shalmaneser I recorded a campaign in which he subdued the entire territory of Uruatri, the Shalmaneser text uses the name Urartu to refer to a geographical region, not a kingdom, and names eight lands contained within Urartu. Urartu is cognate with the Biblical Ararat, Akkadian Urashtu and Armenian Ayrarat, the Urartian toponym Biainili was adopted in the Old Armenian as Van, Վան. Hence the names Kingdom of Van or Vannic Kingdom, scholars such as Carl Ferdinand Friedrich Lehmann-Haupt believed that the people of Urartu called themselves Khaldini after the god Ḫaldi. Boris Piotrovsky wrote that the Urartians first appear in history in the 13th century BC as a league of tribes or countries which did not yet constitute a unitary state. In the Assyrian annals the term Uruatri as a name for this league was superseded during a period of years by the term land of Nairi. Scholars believe that Urartu is an Akkadian variation of Ararat of the Old Testament, indeed, Mount Ararat is located in ancient Urartian territory, approximately 120 kilometres north of its former capital. In addition to referring to the famous Biblical mountain, Ararat also appears as the name of a kingdom in Jeremiah 51,27, mentioned together with Minni, in the early sixth century BC, Urartu was replaced by the Armenian Orontid Dynasty. Shupria was part of the Urartu confederation, later, there is reference to a district in the area called Arme or Urme, which some scholars have linked to the name of Armenia. At its apogee, Urartu stretched from the borders of northern Mesopotamia to the southern Caucasus, including present-day Armenia, archaeological sites within its boundaries include Altintepe, Toprakkale, Patnos and Haykaberd. Urartu fortresses included Erebuni, Van Fortress, Argishtihinili, Anzaf, Haykaberd, schulz discovered and copied numerous cuneiform inscriptions, partly in Assyrian and partly in a hitherto unknown language. Schulz also re-discovered the Kelishin stele, bearing an Assyrian-Urartian bilingual inscription, a summary account of his initial discoveries was published in 1828. Schulz and four of his servants were murdered by Kurds in 1829 near Başkale and his notes were later recovered and published in Paris in 1840

Annual plant
–
An annual plant is a plant that completes its life cycle, from germination to the production of seed, within one year, and then dies. Summer annuals germinate during spring or early summer and mature by autumn of the same year, winter annuals germinate during the autumn and mature during the spring or summer of the following calendar year. One seed-to-seed life cycle for an annual can occur in as little as a month in some species, oilseed rapa can go from seed-to-seed in about five weeks under a bank of fluorescent lamps. This style of growing is used in classrooms for education. Many desert annuals are therophytes, because their life cycle is only weeks. In cultivation, many plants are, or are grown as, annuals. Some perennials and biennials are grown in gardens as annuals for convenience, carrot, celery and parsley are true biennials that are usually grown as annual crops for their edible roots, petioles and leaves, respectively. Tomato, sweet potato and bell pepper are tender perennials usually grown as annuals, ornamental perennials commonly grown as annuals are impatiens, wax begonia, snapdragon, Pelargonium, coleus and petunia. Examples of true annuals include corn, wheat, rice, lettuce, peas, watermelon, beans, zinnia, summer annuals sprout, flower, produce seed, and die, during the warmer months of the year. The lawn weed crabgrass is a summer annual, winter annuals germinate in autumn or winter, live through the winter, then bloom in winter or spring. The plants grow and bloom during the season when most other plants are dormant or other annuals are in seed form waiting for warmer weather to germinate. Winter annuals die after flowering and setting seed, the seeds germinate in the autumn or winter when the soil temperature is cool. Winter annuals typically grow low to the ground, where they are sheltered from the coldest nights by snow cover. Some common winter annuals include henbit, deadnettle, chickweed, ironically, the property that they prevent the soil from drying out can also be problematic for commercial agriculture. In 2008, it was discovered that the inactivation of only two genes in one species of annual plant leads to the conversion into a perennial plant, researchers deactivated the SOC1 and FUL genes in Arabidopsis thaliana, which control flowering time. This switch established phenotypes common in plants, such as wood formation

Glossary of leaf morphology
–
The following is a defined list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple or compound, the edge of the leaf may be regular or irregular, may be smooth or bearing hair, bristles or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article, leaves of most plants include a flat structure called the blade or lamina, but not all leaves are flat, some are cylindrical. Leaves may be simple, with a leaf blade, or compound. In flowering plants, as well as the blade of the leaf, there may be a petiole and stipules, leaf structure is described by several terms that include, Being one of the more visible features, leaf shape is commonly used for plant identification. Edge and margin are both interchangeable in the sense that they refer to the perimeter of a leaf. Leaves may also be folded or rolled in various ways, the folding of leaves within a bud is vernation, ptyxis is the folding of an individual leaf in a bud
25.
Dehiscence (botany)
–
Dehiscence is the splitting at maturity along a built-in line of weakness in a plant structure in order to release its contents, and is common among fruits, anthers and sporangia. Sometimes this involves the complete detachment of a part, structures that open in this way are said to be dehiscent. Structures that do not open in this way are called indehiscent, dehiscence may or may not involve the loss of a structure through the process of abscission. The lost structures are said to be caducous, manipulation of dehiscence can improve crop yield since a trait that causes seed dispersal is a disadvantage for farmers whose goal is to collect the seed. Many of the agronomically important plants have been bred for reduced shattering, explosive dehiscence is a ballistic form of dispersal that flings seeds or spores far from the parent plant. This rapid plant movement can achieve limited dispersal without the assistance of animals, a notable example is the sandbox tree, which can fling seeds 100 meters and has been called the Dynamite tree due to the loud sound of its explosive dehiscence. Another example is Impatiens, whose explosive dehiscence is triggered by being touched, explosive dehiscence of sporangia is a characteristic of Sphagnum. Septicidal and loculicidal dehiscence may not be distinct, in some cases both the septa and the walls of the locules split. Dehiscence occurs through breakage of parts of the enclosing structure, the mechanisms can be classified in various ways. Dehiscence through a hole is referred to as poricidal dehiscence. The pore may have a cover that is referred to as an operculum or it may not, poricidal dehiscence occurs in many unrelated organisms, in fruit, causing the release of seeds, and also in the sporangia of many organisms. Poricidal anthers of flowers are associated with buzz pollination by insects. Circumscissile dehiscence involves a horizontal opening that causes a lid to separate completely and this type of dehiscence occurs in some fruit and anthers and also in some flower buds. Anther dehiscence is the function of the anther that causes the release of pollen grains. This process is coordinated precisely with pollen differentiation, floral development, the anther wall breaks at a specific site. Usually this site is observed as an indentation between the locules of each theca and runs the length of the anther, but in species with poricidal anther dehiscence it is instead a small pore. If the pollen is released from the anther through a split on the side, this is extrorse dehiscence, and if the pollen is released from the inner side. If the pollen is released through a split that is positioned to the side, towards other anthers, rather than towards the inside or outside of the flower, the stomium is the region of the anther where dehiscence occurs

Simit
–
Simits size, crunch, chewiness, and other characteristics vary slightly by region. It is widely known as Turkish bagel in United States, in İzmir, simit is known as gevrek, although it is very similar to the Istanbul variety. Simit in Ankara are smaller and crisper than those of other cities, simeat in Istanbul are made with molasses. The word simit comes from Arabic samīd white bread or fine flour, other names are based on the Greek koulouri, Aramaic qeluro/qelora, or the Turkish gevrek, South Slavic đevrek, ђеврек, gjevrek, ѓеврек, геврек. In Judaeo-Spanish it is known as roskas turkas, simit has a long history in Istanbul. Archival sources show that the simit has been produced in Istanbul since 1525, based on Üsküdar court records dated 1593, the weight and price of simit was standardized for the first time. The 17th-century traveler Evliya Çelebi wrote that there were 70 simit bakeries in Istanbul during the 1630s, jean Brindesis early 19th-century oil paintings about Istanbul daily life show simit sellers on the streets. Warwick Goble, too, made an illustration of these simit sellers of Istanbul in 1906, simit and its variants became popular across the Ottoman Empire. Simit is generally served plain, or for breakfast with tea, fruit preserves, drinking tea with simit is traditional. Simit is a traditional Christmas bread in Armenia, simeat are sold by street vendors in Turkey, who either have a simit trolley or carry the simit in a tray on their head. Street merchants generally advertise simit as fresh since they are baked throughout the day, otherwise hot, simit is an important symbol for lower and middle-class people of Turkey. Sometimes it is called susam kebabı, certain varieties of Romanian covrigi are similar to simit. Another type of similar to simit is known as obwarzanek in Poland and bublik in Russia, Ukraine. The main difference is that the rings of dough are poached briefly in boiling water prior to baking, instead of being dipped in water and molasses syrup, as is the case with simit. Girde, is a type of bread baked on the walls of tandoori oven, that is similar to simit

Sesame oil
–
Sesame oil is an edible vegetable oil derived from sesame seeds. Besides being used as an oil in South India, it is often used as a flavour enhancer in Korean, Chinese, Japanese, Middle Eastern. It has a nutty aroma and taste. The oil from the seed is popular in alternative medicine, from traditional massages. Sesame oil is composed of the fatty acids, linoleic acid, oleic acid, palmitic acid, stearic acid. Historically, sesame was cultivated more than 5000 years ago as a drought-tolerant crop and was able to grow other crops failed. Sesame seeds were one of the first crops processed for oil as well as one of the earliest condiments, sesame was cultivated during the Indus valley civilization and was the main oil crop. It was probably exported to Mesopotamia around 2500 BC, sesame oil is thought to have originated in the Indus Valley of North India, but spread from there throughout Asia. Sesame seeds are protected by a capsule which only bursts when the seeds are completely ripe, the dehiscence time tends to vary, so farmers cut plants by hand and place them together in an upright position to continue ripening until all the capsules have opened. The discovery of an indehiscent mutant by Langham in 1943 began the work towards development of a high-yielding, although researchers have made significant progress in sesame breeding, harvest losses due to dehiscence continue to limit domestic US production. Sesame seeds are produced in developing countries, a factor that has played a role in limiting the creation of large-scale, fully automated oil extraction. Sesame oil can be extracted by a number of methods, depending on the materials, in developed countries sesame oil is often extracted using an expeller press, larger-scale oil extraction machines, or by pressing followed by chemical solvent extraction. Sesame oil can also be extracted under low-temperature conditions using a press in a process called cold pressing. This extraction method is popular among raw food adherents because it avoids exposing the oil to chemical solvents or high temperatures during extraction, many consumers prefer unrefined sesame oil due to their belief that the refining process removes important nutrients. Flavour, which was traditionally an important attribute was best in oils produced from mild crushing, storage in amber-colored bottles can help to minimize light exposure. Sesame oil is a polyunsaturated semi-drying oil, commercial sesame oil varies in colour from light to deep reddish yellow depending on the colour of the seed processed and the method of milling. Provided the oil is milled from well-cleaned seed, it can be refined and bleached easily to yield a light-coloured limpid oil, sesame oil is rich in oleic and linoleic acids, which together account for 85% of the total fatty acids. Sesame oil has a high percentage of unsaponifiable matter in India

Tanzania
–
Tanzania /ˌtænzəˈniːə/, officially the United Republic of Tanzania, is a country in Eastern Africa within the African Great Lakes region. Parts of the country are in Southern Africa, Mount Kilimanjaro, Africas highest mountain, is in northeastern Tanzania. Tanzanias population of 51.82 million is diverse, composed of ethnic, linguistic. Dar es Salaam, the capital, retains most government offices and is the countrys largest city, principal port. Tanzania is a one party dominant state with the Chama Cha Mapinduzi party in power, from its formation until 1992, it was the only legally permitted party in the country. Elections for president and all National Assembly seats were last held in October 2015, the CCM holds approximately 75% of the seats in the assembly. Prehistoric population migrations include Southern Cushitic speakers, who are ancestral to the Iraqw, Gorowa, and Burunge and who moved south from Ethiopia into Tanzania. Based on linguistic evidence, there may also have two movements into Tanzania of Eastern Cushitic people at about 4,000 and 2,000 years ago. These movements took place at about the time as the settlement of the iron-making Mashariki Bantu from West Africa in the Lake Victoria. They brought with them the west African planting tradition and the staple of yams. They subsequently migrated out of these regions across the rest of Tanzania, European colonialism began in mainland Tanzania during the late 19th century when Germany formed German East Africa, which gave way to British rule following World War I. The mainland was governed as Tanganyika, with the Zanzibar Archipelago remaining a separate colonial jurisdiction, following their respective independence in 1961 and 1963, the two entities merged in April 1964 to form the United Republic of Tanzania. Tanzania is mountainous and densely forested in the northeast, where Mount Kilimanjaro is located, three of Africas Great Lakes are partly within Tanzania. To the north and west lie Lake Victoria, Africas largest lake, and Lake Tanganyika, the eastern shore is hot and humid, with the Zanzibar Archipelago just offshore. The Menai Bay Conservation Area is Zanzibars largest marine protected area, over 100 different languages are spoken in Tanzania, making it the most linguistically diverse country in East Africa. Among the languages spoken in Tanzania are all four of Africas language families, Bantu, Cushitic, Nilotic, Swahili and English are Tanzanias official languages. In connection with his Ujamaa social policies, President Nyerere encouraged the use of Swahili, approximately 10% of Tanzanians speak Swahili as a first language, and up to 90% speak it as a second language. Most Tanzanians thus speak both Swahili and a language, many educated Tanzanians are trilingual, also speaking English

India
–
India, officially the Republic of India, is a country in South Asia. It is the seventh-largest country by area, the second-most populous country, and it is bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast. It shares land borders with Pakistan to the west, China, Nepal, and Bhutan to the northeast, in the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives. Indias Andaman and Nicobar Islands share a border with Thailand. The Indian subcontinent was home to the urban Indus Valley Civilisation of the 3rd millennium BCE, in the following millennium, the oldest scriptures associated with Hinduism began to be composed. Social stratification, based on caste, emerged in the first millennium BCE, early political consolidations took place under the Maurya and Gupta empires, the later peninsular Middle Kingdoms influenced cultures as far as southeast Asia. In the medieval era, Judaism, Zoroastrianism, Christianity, and Islam arrived, much of the north fell to the Delhi sultanate, the south was united under the Vijayanagara Empire. The economy expanded in the 17th century in the Mughal empire, in the mid-18th century, the subcontinent came under British East India Company rule, and in the mid-19th under British crown rule. A nationalist movement emerged in the late 19th century, which later, under Mahatma Gandhi, was noted for nonviolent resistance, in 2015, the Indian economy was the worlds seventh largest by nominal GDP and third largest by purchasing power parity. Following market-based economic reforms in 1991, India became one of the major economies and is considered a newly industrialised country. However, it continues to face the challenges of poverty, corruption, malnutrition, a nuclear weapons state and regional power, it has the third largest standing army in the world and ranks sixth in military expenditure among nations. India is a constitutional republic governed under a parliamentary system. It is a pluralistic, multilingual and multi-ethnic society and is home to a diversity of wildlife in a variety of protected habitats. The name India is derived from Indus, which originates from the Old Persian word Hindu, the latter term stems from the Sanskrit word Sindhu, which was the historical local appellation for the Indus River. The ancient Greeks referred to the Indians as Indoi, which translates as The people of the Indus, the geographical term Bharat, which is recognised by the Constitution of India as an official name for the country, is used by many Indian languages in its variations. Scholars believe it to be named after the Vedic tribe of Bharatas in the second millennium B. C. E and it is also traditionally associated with the rule of the legendary emperor Bharata. Gaṇarājya is the Sanskrit/Hindi term for republic dating back to the ancient times, hindustan is a Persian name for India dating back to the 3rd century B. C. E. It was introduced into India by the Mughals and widely used since then and its meaning varied, referring to a region that encompassed northern India and Pakistan or India in its entirety

Sudan
–
Sudan, also known as North Sudan since South Sudans independence and officially the Republic of the Sudan, is a country in Northern Africa. It is the third largest country in Africa, the River Nile divides the country into eastern and western halves. Before the Sudanese Civil War, South Sudan was part of Sudan, Sudan was home to numerous ancient civilizations, such as the Kingdom of Kush, Kerma, Nobatia, Alodia, Makuria, Meroë and others, most of which flourished along the Nile. During the pre-dynastic period Nubia and Nagadan Upper Egypt were identical, by virtue of its proximity to Egypt, the Sudan participated in the wider history of the Near East inasmuch as it was Christianized by the 6th century, and Islamized in the 15th. As a result of Christianization, the Old Nubian language stands as the oldest recorded Nilo-Saharan language, Sudan was the largest country in Africa and the Arab world until 2011, when South Sudan separated into an independent country, following an independence referendum. Sudan is now the third largest country in Africa and also the third largest country in the Arab world and its capital is Khartoum, the political, cultural and commercial centre of the nation. It is a representative democratic federal republic. The politics of Sudan are regulated by an organization called the National Assembly. The Sudanese legal system is based on Islamic law, the countrys place name Sudan is a name given to a geographical region to the south of the Sahara, stretching from Western Africa to eastern Central Africa. The name derives from the Arabic bilād as-sūdān, or the lands of the Blacks, during the fifth millennium BC migrations from the drying Sahara brought neolithic people into the Nile Valley along with agriculture. The population that resulted from this cultural and genetic mixing developed social hierarchy over the centuries become the Kingdom of Kush at 1700 BC. The Kingdom of Kush was an ancient Nubian state centered on the confluences of the Blue Nile and White Nile, and the Atbarah River and it was established after the Bronze Age collapse and the disintegration of the New Kingdom of Egypt, centered at Napata in its early phase. After King Kashta invaded Egypt in the eighth century BC, the Kushite kings ruled as pharaohs of the Twenty-fifth Dynasty of Egypt for a century before being defeated and driven out by the Assyrians. At the height of their glory, the Kushites conquered an empire that stretched from what is now known as South Kordofan all the way to the Sinai, pharaoh Piye attempted to expand the empire into the Near East, but was thwarted by the Assyrian king Sargon II. Sennacheribs successor Esarhaddon went further, and invaded Egypt itself, deposing Taharqa, Taharqa fled back to his homeland where he died two years later. Egypt became an Assyrian colony, however, king Tantamani, after succeeding Taharqa, Esarhaddon died while preparing to leave the Assyrian capital of Nineveh in order to eject him. However, his successor Ashurbanipal sent an army into southern Egypt and routed Tantamani. During Classical Antiquity, the Nubian capital was at Meroë, in ancient Greek geography, the Meroitic kingdom was known as Ethiopia

China
–
China, officially the Peoples Republic of China, is a unitary sovereign state in East Asia and the worlds most populous country, with a population of over 1.381 billion. The state is governed by the Communist Party of China and its capital is Beijing, the countrys major urban areas include Shanghai, Guangzhou, Beijing, Chongqing, Shenzhen, Tianjin and Hong Kong. China is a power and a major regional power within Asia. Chinas landscape is vast and diverse, ranging from forest steppes, the Himalaya, Karakoram, Pamir and Tian Shan mountain ranges separate China from much of South and Central Asia. The Yangtze and Yellow Rivers, the third and sixth longest in the world, respectively, Chinas coastline along the Pacific Ocean is 14,500 kilometers long and is bounded by the Bohai, Yellow, East China and South China seas. China emerged as one of the worlds earliest civilizations in the basin of the Yellow River in the North China Plain. For millennia, Chinas political system was based on hereditary monarchies known as dynasties, in 1912, the Republic of China replaced the last dynasty and ruled the Chinese mainland until 1949, when it was defeated by the communist Peoples Liberation Army in the Chinese Civil War. The Communist Party established the Peoples Republic of China in Beijing on 1 October 1949, both the ROC and PRC continue to claim to be the legitimate government of all China, though the latter has more recognition in the world and controls more territory. China had the largest economy in the world for much of the last two years, during which it has seen cycles of prosperity and decline. Since the introduction of reforms in 1978, China has become one of the worlds fastest-growing major economies. As of 2016, it is the worlds second-largest economy by nominal GDP, China is also the worlds largest exporter and second-largest importer of goods. China is a nuclear weapons state and has the worlds largest standing army. The PRC is a member of the United Nations, as it replaced the ROC as a permanent member of the U. N. Security Council in 1971. China is also a member of numerous formal and informal multilateral organizations, including the WTO, APEC, BRICS, the Shanghai Cooperation Organization, the BCIM, the English name China is first attested in Richard Edens 1555 translation of the 1516 journal of the Portuguese explorer Duarte Barbosa. The demonym, that is, the name for the people, Portuguese China is thought to derive from Persian Chīn, and perhaps ultimately from Sanskrit Cīna. Cīna was first used in early Hindu scripture, including the Mahābhārata, there are, however, other suggestions for the derivation of China. The official name of the state is the Peoples Republic of China. The shorter form is China Zhōngguó, from zhōng and guó and it was then applied to the area around Luoyi during the Eastern Zhou and then to Chinas Central Plain before being used as an occasional synonym for the state under the Qing

Myanmar
–
Myanmar, officially the Republic of the Union of Myanmar and also known as Burma, is a sovereign state in South East Asia bordered by Bangladesh, India, China, Laos and Thailand. About one third of Myanmars total perimeter of 5,876 km, forms an uninterrupted coastline of 1,930 km along the Bay of Bengal, the countrys 2014 census revealed a much lower population than expected, with 51 million people recorded. Myanmar is 676,578 square kilometres in size and its capital city is Naypyidaw and its largest city and former capital city is Yangon. Early civilizations in Myanmar included the Tibeto-Burman-speaking Pyu city-states in Upper Burma, the Pagan Kingdom fell due to the Mongol invasions and several warring states emerged. In the 16th century, reunified by the Taungoo Dynasty, the country was for a period the largest empire in the history of Mainland Southeast Asia. The early 19th century Konbaung Dynasty ruled over an area included modern Myanmar and briefly controlled Manipur. The British invaded Myanmar after three Anglo-Burmese Wars in the 19th century and the became a British colony. Myanmar became an independent nation in 1948, initially as a nation and then, following a coup détat in 1962. For most of its independent years, the country has been engrossed in rampant ethnic strife, during this time, the United Nations and several other organisations have reported consistent and systematic human rights violations in the country. In 2011, the junta was officially dissolved following a 2010 general election. While former military leaders still wield enormous power in the country, there is, however, continuing criticism of the governments treatment of the Muslim Rohingya minority and its poor response to the religious clashes. In the landmark 2015 election, Aung San Suu Kyis party won a majority in both houses, Myanmar is a country rich in jade and gems, oil, natural gas and other mineral resources. In 2013, its GDP stood at US$56.7 billion, the income gap in Myanmar is among the widest in the world, as a large proportion of the economy is controlled by supporters of the former military government. As of 2016, according to the Human Development Index, Myanmar had a level of human development. The renaming remains a contested issue, many political and ethnic opposition groups and countries continue to use Burma because they do not recognise the legitimacy of the ruling military government or its authority to rename the country. The countrys official name is the Republic of the Union of Myanmar. Countries that do not officially recognise that name use the long form Union of Burma instead, in English, the country is popularly known as either Burma or Myanmar /ˈmjɑːnˌmɑːr/. Both these names are derived from the name of the majority Burmese Bamar ethnic group, Myanmar is considered to be the literary form of the name of the group, while Burma is derived from Bamar, the colloquial form of the groups name

Nigeria
–
Its coast in the south lies on the Gulf of Guinea in the Atlantic Ocean. It comprises 36 states and the Federal Capital Territory, where the capital, Nigeria is officially a democratic secular country. Modern-day Nigeria has been the site of numerous kingdoms and tribal states over the millennia, the modern state originated from British colonial rule beginning in the 19th century, and the merging of the Southern Nigeria Protectorate and Northern Nigeria Protectorate in 1914. The British set up administrative and legal structures whilst practising indirect rule through traditional chiefdoms, Nigeria became a formally independent federation in 1960, and plunged into a civil war from 1967 to 1970. Nigeria is often referred to as the Giant of Africa, owing to its large population, with approximately 184 million inhabitants, Nigeria is the most populous country in Africa and the seventh most populous country in the world. Nigeria has one of the largest populations of youth in the world, Nigeria is divided roughly in half between Christians, who live mostly in the southern part of the country, and Muslims in the northern part. A minority of the population practise religions indigenous to Nigeria, such as native to the Igbo. As of 2015, Nigeria is the worlds 20th largest economy, worth more than $500 billion and $1 trillion in terms of nominal GDP and it overtook South Africa to become Africas largest economy in 2014. The 2013 debt-to-GDP ratio was 11 percent, Nigeria is a member of the MINT group of countries, which are widely seen as the globes next BRIC-like economies. It is also listed among the Next Eleven economies set to become among the biggest in the world, Nigeria is a founding member of the African Union and a member of many other international organizations, including the United Nations, the Commonwealth of Nations and OPEC. The name Nigeria was taken from the Niger River running through the country and this name was coined in the late 19th century by British journalist Flora Shaw, who later married Lord Lugard, a British colonial administrator. The origin of the name Niger, which applied only to the middle reaches of the Niger River, is uncertain. The word is likely an alteration of the Tuareg name egerew n-igerewen used by inhabitants along the middle reaches of the river around Timbuktu prior to 19th-century European colonialism. The Nok civilisation of Northern Nigeria flourished between 500 BC and AD200, producing life-sized terracotta figures which are some of the earliest known sculptures in Sub-Saharan Africa, further north, the cities Kano and Katsina have a recorded history dating to around 999 AD. Hausa kingdoms and the Kanem-Bornu Empire prospered as trade posts between North and West Africa, the Kingdom of Nri of the Igbo people consolidated in the 10th century and continued until it lost its sovereignty to the British in 1911. Nri was ruled by the Eze Nri, and the city of Nri is considered to be the foundation of Igbo culture, Nri and Aguleri, where the Igbo creation myth originates, are in the territory of the Umeuri clan. Members of the clan trace their lineages back to the patriarchal king-figure Eri, in West Africa, the oldest bronzes made using the lost-wax process were from Igbo Ukwu, a city under Nri influence. The Yoruba kingdoms of Ife and Oyo in southwestern Nigeria became prominent in the 12th and 14th centuries, the oldest signs of human settlement at Ifes current site date back to the 9th century, and its material culture includes terracotta and bronze figures

United Nations
–
The United Nations is an intergovernmental organization to promote international co-operation. A replacement for the ineffective League of Nations, the organization was established on 24 October 1945 after World War II in order to prevent another such conflict, at its founding, the UN had 51 member states, there are now 193. The headquarters of the UN is in Manhattan, New York City, further main offices are situated in Geneva, Nairobi, and Vienna. The organization is financed by assessed and voluntary contributions from its member states, the UNs mission to preserve world peace was complicated in its early decades by the Cold War between the US and Soviet Union and their respective allies. The organization participated in actions in Korea and the Congo. After the end of the Cold War, the UN took on major military, the UN has six principal organs, the General Assembly, the Security Council, the Economic and Social Council, the Secretariat, the International Court of Justice, and the UN Trusteeship Council. UN System agencies include the World Bank Group, the World Health Organization, the World Food Programme, UNESCO, the UNs most prominent officer is the Secretary-General, an office held by Portuguese António Guterres since 2017. Non-governmental organizations may be granted consultative status with ECOSOC and other agencies to participate in the UNs work, the organization won the Nobel Peace Prize in 2001, and a number of its officers and agencies have also been awarded the prize. Other evaluations of the UNs effectiveness have been mixed, some commentators believe the organization to be an important force for peace and human development, while others have called the organization ineffective, corrupt, or biased. Following the catastrophic loss of life in the First World War, the earliest concrete plan for a new world organization began under the aegis of the US State Department in 1939. It incorporated Soviet suggestions, but left no role for France, four Policemen was coined to refer to four major Allied countries, United States, United Kingdom, Soviet Union, and China, which emerged in the Declaration by United Nations. Roosevelt first coined the term United Nations to describe the Allied countries, the term United Nations was first officially used when 26 governments signed this Declaration. One major change from the Atlantic Charter was the addition of a provision for religious freedom, by 1 March 1945,21 additional states had signed. Each Government pledges itself to cooperate with the Governments signatory hereto, the foregoing declaration may be adhered to by other nations which are, or which may be, rendering material assistance and contributions in the struggle for victory over Hitlerism. During the war, the United Nations became the term for the Allies. To join, countries had to sign the Declaration and declare war on the Axis, at the later meetings, Lord Halifax deputized for Mr. Eden, Wellington Koo for T. V. Soong, and Mr Gromyko for Mr. Molotov. The first meetings of the General Assembly, with 51 nations represented, the General Assembly selected New York City as the site for the headquarters of the UN, and the facility was completed in 1952. Its site—like UN headquarters buildings in Geneva, Vienna, and Nairobi—is designated as international territory, the Norwegian Foreign Minister, Trygve Lie, was elected as the first UN Secretary-General

Italy
–
Italy, officially the Italian Republic, is a unitary parliamentary republic in Europe. Located in the heart of the Mediterranean Sea, Italy shares open land borders with France, Switzerland, Austria, Slovenia, San Marino, Italy covers an area of 301,338 km2 and has a largely temperate seasonal climate and Mediterranean climate. Due to its shape, it is referred to in Italy as lo Stivale. With 61 million inhabitants, it is the fourth most populous EU member state, the Italic tribe known as the Latins formed the Roman Kingdom, which eventually became a republic that conquered and assimilated other nearby civilisations. The legacy of the Roman Empire is widespread and can be observed in the distribution of civilian law, republican governments, Christianity. The Renaissance began in Italy and spread to the rest of Europe, bringing a renewed interest in humanism, science, exploration, Italian culture flourished at this time, producing famous scholars, artists and polymaths such as Leonardo da Vinci, Galileo, Michelangelo and Machiavelli. The weakened sovereigns soon fell victim to conquest by European powers such as France, Spain and Austria. Despite being one of the victors in World War I, Italy entered a period of economic crisis and social turmoil. The subsequent participation in World War II on the Axis side ended in defeat, economic destruction. Today, Italy has the third largest economy in the Eurozone and it has a very high level of human development and is ranked sixth in the world for life expectancy. The country plays a prominent role in regional and global economic, military, cultural and diplomatic affairs, as a reflection of its cultural wealth, Italy is home to 51 World Heritage Sites, the most in the world, and is the fifth most visited country. The assumptions on the etymology of the name Italia are very numerous, according to one of the more common explanations, the term Italia, from Latin, Italia, was borrowed through Greek from the Oscan Víteliú, meaning land of young cattle. The bull was a symbol of the southern Italic tribes and was often depicted goring the Roman wolf as a defiant symbol of free Italy during the Social War. Greek historian Dionysius of Halicarnassus states this account together with the legend that Italy was named after Italus, mentioned also by Aristotle and Thucydides. The name Italia originally applied only to a part of what is now Southern Italy – according to Antiochus of Syracuse, but by his time Oenotria and Italy had become synonymous, and the name also applied to most of Lucania as well. The Greeks gradually came to apply the name Italia to a larger region, excavations throughout Italy revealed a Neanderthal presence dating back to the Palaeolithic period, some 200,000 years ago, modern Humans arrived about 40,000 years ago. Other ancient Italian peoples of undetermined language families but of possible origins include the Rhaetian people and Cammuni. Also the Phoenicians established colonies on the coasts of Sardinia and Sicily, the Roman legacy has deeply influenced the Western civilisation, shaping most of the modern world

Hectare
–
The hectare is an SI accepted metric system unit of area equal to 100 ares and primarily used in the measurement of land as a metric replacement for the imperial acre. An acre is about 0.405 hectare and one hectare contains about 2.47 acres, in 1795, when the metric system was introduced, the are was defined as 100 square metres and the hectare was thus 100 ares or 1⁄100 km2. When the metric system was further rationalised in 1960, resulting in the International System of Units, the are was not included as a recognised unit. The hectare, however, remains as a non-SI unit accepted for use with the SI units, the metric system of measurement was first given a legal basis in 1795 by the French Revolutionary government. At the first meeting of the CGPM in 1889 when a new standard metre, manufactured by Johnson Matthey & Co of London was adopted, in 1960, when the metric system was updated as the International System of Units, the are did not receive international recognition. The units that were catalogued replicated the recommendations of the CGPM, many farmers, especially older ones, still use the acre for everyday calculations, and convert to hectares only for official paperwork. Farm fields can have long histories which are resistant to change, with names such as the six acre field stretching back hundreds of years. The names centiare, deciare, decare and hectare are derived by adding the standard metric prefixes to the base unit of area. The centiare is a synonym for one square metre, the deciare is ten square metres. The are is a unit of area, equal to 100 square metres and it was defined by older forms of the metric system, but is now outside of the modern International System of Units. It is commonly used to measure real estate, in particular in Indonesia, India, and in French-, Portuguese-, Slovakian-, Serbian-, Czech-, Polish-, Dutch-, in Russia and other former Soviet Union states, the are is called sotka. It is used to describe the size of suburban dacha or allotment garden plots or small city parks where the hectare would be too large, the decare is derived from deka, the prefix for 10 and are, and is equal to 10 ares or 1000 square metres. It is used in Norway and in the former Ottoman areas of the Middle East, the hectare, although not strictly a unit of SI, is the only named unit of area that is accepted for use within the SI. The United Kingdom, United States, Burma, and to some extent Canada instead use the acre, others, such as South Africa, published conversion factors which were to be used particularly when preparing consolidation diagrams by compilation. In many countries, metrication redefined or clarified existing measures in terms of metric units, non-SI units accepted for use with the International System of Units

Cash crop
–
A cash crop is an agricultural crop which is grown for sale to return a profit. It is typically purchased by parties separate from a farm, the term is used to differentiate marketed crops from subsistence crops, which are those fed to the producers own livestock or grown as food for the producers family. In earlier times cash crops were only a small part of a farms total yield, while today, especially in developed countries. In the least developed countries, cash crops are usually crops which attract demand in developed nations. Prices for major crops are set in commodity markets with global scope, with some local variation based on freight costs and local supply. A consequence of this is that a nation, region, or individual producer relying on such a crop may suffer low prices should a bumper crop elsewhere lead to excess supply on the global markets and this system has been criticized by traditional farmers. Coffee is an example of a product that has been susceptible to significant commodity futures price variations, Issues involving subsidies and trade barriers on such crops have become controversial in discussions of globalization. The practice of exporting at artificially low prices is known as dumping, the Arctic climate is generally not conducive for the cultivation of cash crops. However, one potential cash crop for the Arctic is Rhodiola rosea, there is currently consumer demand for the plant, but the available supply is less than the demand. Cash crops grown in regions with a temperate climate include many cereals, oil-yielding crops, vegetables, tree fruit or top fruit, in regions with a subtropical climate, oil-yielding crops and some vegetables and herbs are the predominant cash crops. In regions with a climate, coffee, cocoa, sugar cane, bananas, oranges, cotton. The oil palm is a palm tree, and the fruit from it is used to make palm oil. Around 60 percent of African workers are employed in the agricultural sector, for example, in Burkina Faso 85% of its residents are reliant upon cotton production for income, and over half of the countrys population lives in poverty. Larger farms tend to grow crops such as coffee, tea, cotton, cocoa, fruit. These farms, typically operated by corporations, cover tens of square kilometres. Subsistence farms provide a source of food and a small income for families. Africa has realized significant growth in plantations, many of which are on lands which were purchased by British companies. Jatropha curcas is a crop grown for biofuel production in Africa

Food energy
–
Food energy is chemical energy that animals derive from food and molecular oxygen through the process of cellular respiration. Humans and other animals need a minimum intake of energy to sustain their metabolism. Foods are composed chiefly of carbohydrates, fats, proteins, alcohol, water, vitamins, carbohydrates, fats, proteins, alcohol, and water represent virtually all the weight of food, with vitamins and minerals making up only a small percentage of the weight. Organisms derive food energy from carbohydrates, fats and proteins as well as organic acids, polyols. Some diet components that provide little or no energy, such as water, minerals, vitamins, cholesterol. Water, minerals, vitamins, and cholesterol are not broken down, fiber, a type of carbohydrate, cannot be completely digested by the human body. Ruminants can extract energy from the respiration of cellulose because of bacteria in their rumens. Using the International System of Units, researchers measure energy in joules or in its multiples, the kilojoule is most often used for food-related quantities. An older metric system unit of energy, still used in food-related contexts, is the calorie, more precisely. Within the European Union, both the kilocalorie and kilojoule appear on nutrition labels, in many countries, only one of the units is displayed, in the US and Canada labels spell out the unit as calorie or as Calorie. Fats and ethanol have the greatest amount of energy per gram,37 and 29 kJ/g. Proteins and most carbohydrates have about 17 kJ/g, carbohydrates that are not easily absorbed, such as fiber, or lactose in lactose-intolerant individuals, contribute less food energy. Polyols and organic acids contribute 10 kJ/g and 13 kJ/g respectively, the amount of water, fat, and fiber in foods determines those foods energy density. Theoretically, one could measure food energy in different ways, using the Gibbs free energy of combustion, however, the convention is to use the heat of the oxidation reaction, with the water substance produced being in the liquid phase. The American chemist Wilbur Atwater worked these corrections out in the late 19th century, based on the work of Atwater, it became common practice to calculate energy content of foods using 4 kcal/g for carbohydrates and proteins and 9 kcal/g for lipids. The system was improved by Annabel Merrill and Bernice Watt of the USDA. Many governments require food manufacturers to label the energy content of their products, in the European Union, manufacturers of packaged food must label the nutritional energy of their products in both kilocalories and kilojoules, when required. In Australia and New Zealand, the energy must be stated in kilojoules

Carbohydrate
–
A carbohydrate is a biological molecule consisting of carbon, hydrogen and oxygen atoms, usually with a hydrogen–oxygen atom ratio of 2,1, in other words, with the empirical formula Cmn. This formula holds true for monosaccharides, some exceptions exist, for example, deoxyribose, a sugar component of DNA, has the empirical formula C5H10O4. Carbohydrates are technically hydrates of carbon, structurally it is accurate to view them as polyhydroxy aldehydes and ketones. The term is most common in biochemistry, where it is a synonym of saccharide, a group that includes sugars, starch, the saccharides are divided into four chemical groups, monosaccharides, disaccharides, oligosaccharides, and polysaccharides. Monosaccharides and disaccharides, the smallest carbohydrates, are referred to as sugars. The word saccharide comes from the Greek word σάκχαρον, meaning sugar, while the scientific nomenclature of carbohydrates is complex, the names of the monosaccharides and disaccharides very often end in the suffix -ose. For example, grape sugar is the glucose, cane sugar is the disaccharide sucrose. Carbohydrates perform numerous roles in living organisms, polysaccharides serve for the storage of energy and as structural components. The 5-carbon monosaccharide ribose is an important component of coenzymes and the backbone of the genetic molecule known as RNA, the related deoxyribose is a component of DNA. Saccharides and their derivatives include many other important biomolecules that play key roles in the system, fertilization, preventing pathogenesis, blood clotting. In food science and in informal contexts, the term carbohydrate often means any food that is particularly rich in the complex carbohydrate starch or simple carbohydrates. Often in lists of information, such as the USDA National Nutrient Database, the term carbohydrate is used for everything other than water, protein, fat, ash. This will include chemical compounds such as acetic or lactic acid, carbohydrates are found in wide variety of foods. The important sources are cereals, potatoes, sugarcane, fruits, table sugar, bread, milk, starch and sugar are the important carbohydrates in our diet. Starch is abundant in potatoes, maize, rice and other cereals, sugar appears in our diet mainly as sucrose which is added to drinks and many prepared foods such as jam, biscuits and cakes. Glucose and fructose are found naturally in fruits and some vegetables. Glycogen is carbohydrate found in the liver and muscles, cellulose in the cell wall of all plant tissue is a carbohydrate. It is important in our diet as fibre which helps to maintain a healthy digestive system, formerly the name carbohydrate was used in chemistry for any compound with the formula Cm n

Sugar
–
Sugar is the generic name for sweet, soluble carbohydrates, many of which are used in food. There are various types of derived from different sources. Simple sugars are called monosaccharides and include glucose, fructose, the table sugar or granulated sugar most customarily used as food is sucrose, a disaccharide of glucose and fructose. Sugar is used in prepared foods and it is added to some foods, in the body, sucrose is hydrolysed into the simple sugars fructose and glucose. Other disaccharides include maltose from malted grain, and lactose from milk, longer chains of sugars are called oligosaccharides or polysaccharides. Some other chemical substances, such as glycerol may also have a sweet taste, low-calorie food substitutes for sugar, described as artificial sweeteners, include aspartame and sucralose, a chlorinated derivative of sucrose. Sugars are found in the tissues of most plants and are present in sufficient concentrations for efficient commercial extraction in sugarcane, the world production of sugar in 2011 was about 168 million tonnes. The average person consumes about 24 kilograms of sugar each year, equivalent to over 260 food calories per person, since the latter part of the twentieth century, it has been questioned whether a diet high in sugars, especially refined sugars, is good for human health. Sugar has been linked to obesity, and suspected of, or fully implicated as a cause in the occurrence of diabetes, cardiovascular disease, dementia, macular degeneration, the etymology reflects the spread of the commodity. The English word sugar ultimately originates from the Sanskrit शर्करा, via Arabic سكر as granular or candied sugar, the contemporary Italian word is zucchero, whereas the Spanish and Portuguese words, azúcar and açúcar, respectively, have kept a trace of the Arabic definite article. The Old French word is zuchre and the contemporary French, sucre, the earliest Greek word attested is σάκχαρις. The English word jaggery, a brown sugar made from date palm sap or sugarcane juice, has a similar etymological origin – Portuguese jagara from the Sanskrit शर्करा. Sugar has been produced in the Indian subcontinent since ancient times and it was not plentiful or cheap in early times and honey was more often used for sweetening in most parts of the world. Originally, people chewed raw sugarcane to extract its sweetness, sugarcane was a native of tropical South Asia and Southeast Asia. Different species seem to have originated from different locations with Saccharum barberi originating in India and S. edule, one of the earliest historical references to sugarcane is in Chinese manuscripts dating back to 8th century BC that state that the use of sugarcane originated in India. Sugar was found in Europe by the 1st century AD, but only as an imported medicine and it is a kind of honey found in cane, white as gum, and it crunches between the teeth. It comes in lumps the size of a hazelnut, sugar is used only for medical purposes. Sugar remained relatively unimportant until the Indians discovered methods of turning sugarcane juice into granulated crystals that were easier to store, crystallized sugar was discovered by the time of the Imperial Guptas, around the 5th century AD

Dietary fiber
–
Dietary fiber or roughage is the indigestible portion of food derived from plants. It has two components, Soluble fiber, which dissolves in water, is readily fermented in the colon into gases and physiologically active byproducts. It delays gastric emptying which in turn can cause a feeling of fullness. Insoluble fiber, which does not dissolve in water, is inert and provides bulking, or it can be prebiotic. Bulking fibers absorb water as they move through the digestive system, Dietary fibers can act by changing the nature of the contents of the gastrointestinal tract and by changing how other nutrients and chemicals are absorbed. Some types of soluble fiber absorb water to become a gelatinous, viscous substance which is fermented by bacteria in the digestive tract, some types of insoluble fiber have bulking action and are not fermented. Lignin, a major dietary insoluble fiber source, may alter the rate, other types of insoluble fiber, notably resistant starch, are fully fermented. A novel position has been adopted by the US Department of Agriculture to include functional fibers as isolated fiber sources that may be included in the diet, the term fiber is something of a misnomer, since many types of so-called dietary fiber are not actually fibrous. Food sources of fiber are often divided according to whether they provide soluble or insoluble fiber. Plant foods contain both types of fiber in varying degrees, according to the plants characteristics, a disadvantage of a diet high in fiber is the potential for significant intestinal gas production and bloating.
