Berkeley is a city on the east shore of San Francisco Bay in northern Alameda County, California. It is named after philosopher George Berkeley, it borders the cities of Oakland and Emeryville to the south and the city of Albany and the unincorporated community of Kensington to the north. Its eastern border with Contra Costa County follows the ridge of the Berkeley Hills; the 2010 census recorded a population of 112,580. Berkeley is home to the oldest campus in the University of California system, the University of California and the Lawrence Berkeley National Laboratory, managed and operated by the University, it has the Graduate Theological Union, one of the largest religious studies institutions in the world. Berkeley is considered one of the most liberal cities in the United States; the site of today's City of Berkeley was the territory of the Chochenyo/Huchiun band of the Ohlone people when the first Europeans arrived. Evidence of their existence in the area include pits in rock formations, which they used to grind acorns, a shellmound, now leveled and covered up, along the shoreline of San Francisco Bay at the mouth of Strawberry Creek.
Other artifacts were discovered in the 1950s in the downtown area during remodeling of a commercial building, near the upper course of the creek. The first people of European descent arrived with the De Anza Expedition in 1776. Today, this is noted by signage on Interstate 80, which runs along the San Francisco Bay shoreline of Berkeley; the De Anza Expedition led to establishment of the Spanish Presidio of San Francisco at the entrance to San Francisco Bay. Luis Peralta was among the soldiers at the Presidio. For his services to the King of Spain, he was granted a vast stretch of land on the east shore of San Francisco Bay for a ranch, including that portion that now comprises the City of Berkeley. Luis Peralta named his holding "Rancho San Antonio"; the primary activity of the ranch was raising cattle for meat and hides, but hunting and farming were pursued. Peralta gave portions of the ranch to each of his four sons. What is now Berkeley lies in the portion that went to Peralta's son Domingo, with a little in the portion that went to another son, Vicente.
No artifact survives of the Domingo or Vicente ranches, but their names survive in Berkeley street names. However, legal title to all land in the City of Berkeley remains based on the original Peralta land grant; the Peraltas' Rancho San Antonio continued after Alta California passed from Spanish to Mexican sovereignty after the Mexican War of Independence. However, the advent of U. S. sovereignty after the Mexican–American War, the Gold Rush, saw the Peraltas' lands encroached on by squatters and diminished by dubious legal proceedings. The lands of the brothers Domingo and Vicente were reduced to reservations close to their respective ranch homes; the rest of the land was parceled out to various American claimants. Politically, the area that became Berkeley was part of a vast Contra Costa County. On March 25, 1853, Alameda County was created from a division of Contra Costa County, as well as from a small portion of Santa Clara County; the area that became Berkeley was the northern part of the "Oakland Township" subdivision of Alameda County.
During this period, "Berkeley" was a mix of open land and ranches, with a small, though busy, wharf by the bay. In 1866, Oakland's private College of California looked for a new site, it settled on a location north of Oakland along the foot of the Contra Costa Range astride Strawberry Creek, at an elevation about 500 feet above the bay, commanding a view of the Bay Area and the Pacific Ocean through the Golden Gate. According to the Centennial Record of the University of California, "In 1866…at Founders' Rock, a group of College of California men watched two ships standing out to sea through the Golden Gate. One of them, Frederick Billings, thought of the lines of the Anglo-Irish Anglican Bishop George Berkeley,'westward the course of empire takes its way,' and suggested that the town and college site be named for the eighteenth-century Anglo-Irish philosopher." The philosopher's name is pronounced BARK-lee, but the city's name, to accommodate American English, is pronounced BERK-lee. The College of California's College Homestead Association planned to raise funds for the new campus by selling off adjacent parcels of land.
To this end, they laid out a plat and street grid that became the basis of Berkeley's modern street plan. Their plans fell far short of their desires, they began a collaboration with the State of California that culminated in 1868 with the creation of the public University of California; as construction began on the new site, more residences were constructed in the vicinity of the new campus. At the same time, a settlement of residences and various industries grew around the wharf area called "Ocean View". A horsecar ran from Temescal in Oakland to the university campus along; the first post office opened in 1872. By the 1870s, the Transcontinental Railroad reached its terminus in Oakland. In 1876, a branch line of the Central Pacific Railroad, the Berkeley Branch Railroad, was laid from a junction with the mainline called Shellmound into what is now downtown Berkeley; that same year, the mainline of the transcontinental railroad into Oakland was re-routed, putting the right-of-way along the bay shore through Ocean View.
There was a strong prohibition movement in Berkel
Botany called plant science, plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist; the term "botany" comes from the Ancient Greek word βοτάνη meaning "pasture", "grass", or "fodder". Traditionally, botany has included the study of fungi and algae by mycologists and phycologists with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists study 410,000 species of land plants of which some 391,000 species are vascular plants, 20,000 are bryophytes. Botany originated in prehistory as herbalism with the efforts of early humans to identify – and cultivate – edible and poisonous plants, making it one of the oldest branches of science. Medieval physic gardens attached to monasteries, contained plants of medical importance, they were forerunners of the first botanical gardens attached to universities, founded from the 1540s onwards.
One of the earliest was the Padua botanical garden. These gardens facilitated the academic study of plants. Efforts to catalogue and describe their collections were the beginnings of plant taxonomy, led in 1753 to the binomial system of Carl Linnaeus that remains in use to this day. In the 19th and 20th centuries, new techniques were developed for the study of plants, including methods of optical microscopy and live cell imaging, electron microscopy, analysis of chromosome number, plant chemistry and the structure and function of enzymes and other proteins. In the last two decades of the 20th century, botanists exploited the techniques of molecular genetic analysis, including genomics and proteomics and DNA sequences to classify plants more accurately. Modern botany is a broad, multidisciplinary subject with inputs from most other areas of science and technology. Research topics include the study of plant structure and differentiation, reproduction and primary metabolism, chemical products, diseases, evolutionary relationships and plant taxonomy.
Dominant themes in 21st century plant science are molecular genetics and epigenetics, which are the mechanisms and control of gene expression during differentiation of plant cells and tissues. Botanical research has diverse applications in providing staple foods, materials such as timber, rubber and drugs, in modern horticulture and forestry, plant propagation and genetic modification, in the synthesis of chemicals and raw materials for construction and energy production, in environmental management, the maintenance of biodiversity. Botany originated as the study and use of plants for their medicinal properties. Many records of the Holocene period date early botanical knowledge as far back as 10,000 years ago; this early unrecorded knowledge of plants was discovered in ancient sites of human occupation within Tennessee, which make up much of the Cherokee land today. The early recorded history of botany includes many ancient writings and plant classifications. Examples of early botanical works have been found in ancient texts from India dating back to before 1100 BC, in archaic Avestan writings, in works from China before it was unified in 221 BC.
Modern botany traces its roots back to Ancient Greece to Theophrastus, a student of Aristotle who invented and described many of its principles and is regarded in the scientific community as the "Father of Botany". His major works, Enquiry into Plants and On the Causes of Plants, constitute the most important contributions to botanical science until the Middle Ages seventeen centuries later. Another work from Ancient Greece that made an early impact on botany is De Materia Medica, a five-volume encyclopedia about herbal medicine written in the middle of the first century by Greek physician and pharmacologist Pedanius Dioscorides. De Materia Medica was read for more than 1,500 years. Important contributions from the medieval Muslim world include Ibn Wahshiyya's Nabatean Agriculture, Abū Ḥanīfa Dīnawarī's the Book of Plants, Ibn Bassal's The Classification of Soils. In the early 13th century, Abu al-Abbas al-Nabati, Ibn al-Baitar wrote on botany in a systematic and scientific manner. In the mid-16th century, "botanical gardens" were founded in a number of Italian universities – the Padua botanical garden in 1545 is considered to be the first, still in its original location.
These gardens continued the practical value of earlier "physic gardens" associated with monasteries, in which plants were cultivated for medical use. They supported the growth of botany as an academic subject. Lectures were given about the plants grown in the gardens and their medical uses demonstrated. Botanical gardens came much to northern Europe. Throughout this period, botany remained subordinate to medicine. German physician Leonhart Fuchs was one of "the three German fathers of botany", along with theologian Otto Brunfels and physician Hieronymus Bock. Fuchs and Brunfels broke away from the tradition of copying earlier works to make original observations of their own. Bock created his own system of plant classification. Physician Valerius Cordus authored a botanically and pharmacologically important herbal Historia Plantarum in 1544 and a pharmacopoeia of lasting importance, the Dispensatorium
University of London
The University of London is a collegiate federal research university located in London, England. As of October 2018, the university contains 18 member institutions, central academic bodies and research institutes; the university has over 52,000 distance learning external students and 161,270 campus-based internal students, making it the largest university by number of students in the United Kingdom. The university was established by royal charter in 1836, as a degree-awarding examination board for students holding certificates from University College London and King's College London and "other such other Institutions, corporate or unincorporated, as shall be established for the purpose of Education, whether within the Metropolis or elsewhere within our United Kingdom", allowing it to be one of three institutions to claim the title of the third-oldest university in England, moved to a federal structure in 1900, it is now incorporated by its fourth royal charter and governed by the University of London Act 1994.
It was the first university in the United Kingdom to introduce examinations for women in 1869 and, a decade the first to admit women to degrees. In 1948 it became the first British university to appoint a woman as its vice chancellor; the university's colleges house the oldest teaching hospitals in England. For most practical purposes, ranging from admissions to funding, the constituent colleges operate on an independent basis, with many awarding their own degrees whilst remaining in the federal university; the largest colleges by enrolment as of 2016/17 are UCL, King's College London, Queen Mary, the London School of Economics, Royal Holloway, Goldsmiths, each of which has over 9,000 students. Smaller, more specialist, colleges are the School of Oriental and African Studies, St George's, the Royal Veterinary College, London Business School, the London School of Hygiene and Tropical Medicine, the Royal Central School of Speech and Drama, the Royal Academy of Music, the Courtauld Institute of Art, the Institute of Cancer Research.
Imperial College London was a member from 1907 before it became an independent university in 2007, Heythrop College was a member from 1970 until its closure in 2018. City is the most recent constituent college, having joined on 1 September 2016; as of 2015, there are around 2 million University of London alumni across the world, including 12 monarchs or royalty, 52 presidents or prime ministers, 84 Nobel laureates, 6 Grammy winners, 2 Oscar winners, 3 Olympic gold medalists and the "Father of the Nation" of several countries. University College London was founded under the name “London University” in 1826 as a secular alternative to the universities of Oxford and Cambridge, which limited their degrees to members of the established Church of England; as a result of the controversy surrounding UCL's establishment, King's College London was founded as an Anglican college by royal charter in 1829. In 1830, UCL applied for a royal charter as a university; this was rejected, but renewed in 1834. In response to this, opposition to "exclusive" rights grew among the London medical schools.
The idea of a general degree awarding body for the schools was discussed in the medical press. And in evidence taken by the Select Committee on Medical Education. However, the blocking of a bill to open up Oxford and Cambridge degrees to dissenters led to renewed pressure on the Government to grant degree awarding powers to an institution that would not apply religious tests as the degrees of the new University of Durham were to be closed to non-Anglicans. In 1835, the government announced the response to UCL's petition for a charter. Two charters would be issued, one to UCL incorporating it as a college rather than a university, without degree awarding powers, a second "establishing a Metropolitan University, with power to grant academical degrees to those who should study at the London University College, or at any similar institution which his Majesty might please hereafter to name". Following the issuing of its charter on 28 November 1836, the new University of London started drawing up regulations for degrees in March 1837.
The death of William IV in June, resulted in a problem – the charter had been granted "during our Royal will and pleasure", meaning it was annulled by the king's death. Queen Victoria issued a second charter on 5 December 1837; the university awarded its first degrees in 1839, all to King's College. The university established by the charters of 1836 and 1837 was an examining board with the right to award degrees in arts and medicine. However, the university did not have the authority to grant degrees in theology, considered the senior faculty in the other three English universities. In medicine, the university was given the right to determine which medical schools provided sufficient medical training. In arts and law, by contrast, it would examine students from UCL, King's College, or any other school or college granted a royal warrant giving the government control of which colleges could affiliate to the university. Beyond the right to submit students for examination, there was no other connection between the affiliated colleges and the university.
In 1849 the university held its first graduation ceremony at Somerset House following a petition to the senate from the graduates, who had received their degrees without any ceremony. About 250 students graduated at this ceremony; the London academic robes of this period were distinguished by their "rich velvet facings". The list of affiliated colleges g
Anthoceros is a genus of hornworts in the family Anthocerotaceae. The genus is global in its distribution, its name means'flower horn', refers to the characteristic horn-shaped sporophytes that all hornworts produce. Species of Anthoceros are characterized by having a small to medium-sized, green thallus, more or less lobed along the margins; the spores are dark gray, dark brown or black, this is the easiest way to distinguish Anthoceros from the related genus Phaeoceros, which produces spores that are yellow. The sporophytes of Anthoceros are larger and much more complex than those of Riccia and Pellia, it is differentiated into a constriction like intermediate zone and a capsule. There is no seta, it arises in clusters from the dorsal surface of the thallus each surrounded at the base a tubular involucre. Anthoceros species are host to species of Nostoc, a symbiotic relationship in which Nostoc provides nitrogen to its host through cells known as heterocysts, which are able to carry out photosynthesis.
The Nostoc colonies are present on the lower ventral surface and are visible as blue-green patches which open outwards by slime pores. This hornwort grows in moist clay soils on hills, in ditches, in damp hollows among rocks; the adult plant body is a gametophyte. Species include: Anthoceros agrestis Anthoceros himalayensis Anthoceros hispidus Anthoceros lamellatus Anthoceros neesii Anthoceros punctatus Anthoceros sambesianus Anthoceros scariosus Anthoceros tristanianus
Biology is the natural science that studies life and living organisms, including their physical structure, chemical processes, molecular interactions, physiological mechanisms and evolution. Despite the complexity of the science, there are certain unifying concepts that consolidate it into a single, coherent field. Biology recognizes the cell as the basic unit of life, genes as the basic unit of heredity, evolution as the engine that propels the creation and extinction of species. Living organisms are open systems that survive by transforming energy and decreasing their local entropy to maintain a stable and vital condition defined as homeostasis. Sub-disciplines of biology are defined by the research methods employed and the kind of system studied: theoretical biology uses mathematical methods to formulate quantitative models while experimental biology performs empirical experiments to test the validity of proposed theories and understand the mechanisms underlying life and how it appeared and evolved from non-living matter about 4 billion years ago through a gradual increase in the complexity of the system.
See branches of biology. The term biology is derived from the Greek word βίος, bios, "life" and the suffix -λογία, -logia, "study of." The Latin-language form of the term first appeared in 1736 when Swedish scientist Carl Linnaeus used biologi in his Bibliotheca botanica. It was used again in 1766 in a work entitled Philosophiae naturalis sive physicae: tomus III, continens geologian, phytologian generalis, by Michael Christoph Hanov, a disciple of Christian Wolff; the first German use, was in a 1771 translation of Linnaeus' work. In 1797, Theodor Georg August Roose used the term in the preface of a book, Grundzüge der Lehre van der Lebenskraft. Karl Friedrich Burdach used the term in 1800 in a more restricted sense of the study of human beings from a morphological and psychological perspective; the term came into its modern usage with the six-volume treatise Biologie, oder Philosophie der lebenden Natur by Gottfried Reinhold Treviranus, who announced: The objects of our research will be the different forms and manifestations of life, the conditions and laws under which these phenomena occur, the causes through which they have been effected.
The science that concerns itself with these objects we will indicate by the name biology or the doctrine of life. Although modern biology is a recent development, sciences related to and included within it have been studied since ancient times. Natural philosophy was studied as early as the ancient civilizations of Mesopotamia, the Indian subcontinent, China. However, the origins of modern biology and its approach to the study of nature are most traced back to ancient Greece. While the formal study of medicine dates back to Hippocrates, it was Aristotle who contributed most extensively to the development of biology. Important are his History of Animals and other works where he showed naturalist leanings, more empirical works that focused on biological causation and the diversity of life. Aristotle's successor at the Lyceum, wrote a series of books on botany that survived as the most important contribution of antiquity to the plant sciences into the Middle Ages. Scholars of the medieval Islamic world who wrote on biology included al-Jahiz, Al-Dīnawarī, who wrote on botany, Rhazes who wrote on anatomy and physiology.
Medicine was well studied by Islamic scholars working in Greek philosopher traditions, while natural history drew on Aristotelian thought in upholding a fixed hierarchy of life. Biology began to develop and grow with Anton van Leeuwenhoek's dramatic improvement of the microscope, it was that scholars discovered spermatozoa, bacteria and the diversity of microscopic life. Investigations by Jan Swammerdam led to new interest in entomology and helped to develop the basic techniques of microscopic dissection and staining. Advances in microscopy had a profound impact on biological thinking. In the early 19th century, a number of biologists pointed to the central importance of the cell. In 1838, Schleiden and Schwann began promoting the now universal ideas that the basic unit of organisms is the cell and that individual cells have all the characteristics of life, although they opposed the idea that all cells come from the division of other cells. Thanks to the work of Robert Remak and Rudolf Virchow, however, by the 1860s most biologists accepted all three tenets of what came to be known as cell theory.
Meanwhile and classification became the focus of natural historians. Carl Linnaeus published a basic taxonomy for the natural world in 1735, in the 1750s introduced scientific names for all his species. Georges-Louis Leclerc, Comte de Buffon, treated species as artificial categories and living forms as malleable—even suggesting the possibility of common descent. Although he was opposed to evolution, Buffon is a key figure in the history of evolutionary thought. Serious evolutionary thinking originated with the works of Jean-Baptiste Lamarck, the first to present a coherent theory of evolution, he posited that evolution was the result of environmental stress on properties of animals, meaning that the more and rigorously an organ was used, the more complex and efficient it would become, thus adapting the animal to its environment. Lamarck believed that these acquired traits could be passed on to the animal's offspring, who would
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance, i.e. external morphology, as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology. This is in contrast to physiology, which deals with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts; the word "morphology" is from the Ancient Greek μορφή, morphé, meaning "form", λόγος, lógos, meaning "word, research". While the concept of form in biology, opposed to function, dates back to Aristotle, the field of morphology was developed by Johann Wolfgang von Goethe and independently by the German anatomist and physiologist Karl Friedrich Burdach. Among other important theorists of morphology are Lorenz Oken, Georges Cuvier, Étienne Geoffroy Saint-Hilaire, Richard Owen, Karl Gegenbaur and Ernst Haeckel.
In 1830, Cuvier and E. G. Saint-Hilaire engaged in a famous debate, said to exemplify the two major deviations in biological thinking at the time – whether animal structure was due to function or evolution. Comparative morphology is analysis of the patterns of the locus of structures within the body plan of an organism, forms the basis of taxonomical categorization. Functional morphology is the study of the relationship between the structure and function of morphological features. Experimental morphology is the study of the effects of external factors upon the morphology of organisms under experimental conditions, such as the effect of genetic mutation. "Anatomy" is a "branch of morphology that deals with the structure of organisms". Molecular Morphology is a term used in English-speaking countries for describing the structure of compound molecules, such as polymers and ribonucleic acid. Gross Morphology refers to the collective structures of an organism as a whole as a general description of the form and structure of an organism, taking into account all of its structures without specifying an individual structure.
Most taxa differ morphologically from other taxa. Related taxa differ much less than more distantly related ones, but there are exceptions to this. Cryptic species are species which look similar, or even outwardly identical, but are reproductively isolated. Conversely, sometimes unrelated taxa acquire a similar appearance as a result of convergent evolution or mimicry. In addition, there can be morphological differences within a species, such as in Apoica flavissima where queens are smaller than workers. A further problem with relying on morphological data is that what may appear, morphologically speaking, to be two distinct species, may in fact be shown by DNA analysis to be a single species; the significance of these differences can be examined through the use of allometric engineering in which one or both species are manipulated to phenocopy the other species. A step relevant to the evaluation of morphology between traits/features within species, includes an assessment of the terms: homology and homoplasy.
Homology between features indicate. Alternatively, homoplasy between features describes those that can resemble each other, but derive independently via parallel or convergent evolution. Invention and development of microscopy enable the observation of 3-D cell morphology with both high spatial and temporal resolution; the dynamic processes of these cell morphology which are controlled by a complex system play an important role in varied important biological process, such as immune and invasive responses.

The Marchantiophyta are a division of non-vascular land plants referred to as hepatics or liverworts. Like mosses and hornworts, they have a gametophyte-dominant life cycle, in which cells of the plant carry only a single set of genetic information, it is estimated. Some of the more familiar species grow as a flattened leafless thallus, but most species are leafy with a form much like a flattened moss. Leafy species can be distinguished from the similar mosses on the basis of a number of features, including their single-celled rhizoids. Leafy liverworts differ from most mosses in that their leaves never have a costa and may bear marginal cilia. Other differences are not universal for all mosses and liverworts, but the occurrence of leaves arranged in three ranks, the presence of deep lobes or segmented leaves, or a lack of differentiated stem and leaves all point to the plant being a liverwort. Liverworts are small from 2–20 mm wide with individual plants less than 10 cm long, are therefore overlooked.
However, certain species may cover large patches of ground, trees or any other reasonably firm substrate on which they occur. They are distributed globally in every available habitat, most in humid locations although there are desert and Arctic species as well; some species can be a weed in gardens. Most liverworts are small, measuring from 2–20 millimetres wide with individual plants less than 10 centimetres long, so they are overlooked; the most familiar liverworts consist of a prostrate, ribbon-like or branching structure called a thallus. However, most liverworts produce flattened stems with overlapping scales or leaves in two or more ranks, the middle rank is conspicuously different from the outer ranks. Liverworts can most reliably be distinguished from the similar mosses by their single-celled rhizoids. Other differences are not universal for all mosses and all liverworts. Unlike any other embryophytes, most liverworts contain unique membrane-bound oil bodies containing isoprenoids in at least some of their cells, lipid droplets in the cytoplasm of all other plants being unenclosed.
The overall physical similarity of some mosses and leafy liverworts means that confirmation of the identification of some groups can be performed with certainty only with the aid of microscopy or an experienced bryologist. Liverworts have a gametophyte-dominant life cycle, with the sporophyte dependent on the gametophyte. Cells in a typical liverwort plant each contain only a single set of genetic information, so the plant's cells are haploid for the majority of its life cycle; this contrasts with the pattern exhibited by nearly all animals and by most other plants. In the more familiar seed plants, the haploid generation is represented only by the tiny pollen and the ovule, while the diploid generation is the familiar tree or other plant. Another unusual feature of the liverwort life cycle is that sporophytes are short-lived, withering away not long after releasing spores. In other bryophytes, the sporophyte is persistent and disperses spores over an extended period; the life of a liverwort starts from the germination of a haploid spore to produce a protonema, either a mass of thread-like filaments or else a flattened thallus.
The protonema is a transitory stage in the life of a liverwort, from which will grow the mature gametophore plant that produces the sex organs. The male organs produce the sperm cells. Clusters of antheridia are enclosed by a protective layer of cells called the perigonium; as in other land plants, the female organs are known as archegonia and are protected by the thin surrounding perichaetum. Each archegonium has a slender hollow tube, the "neck", down which the sperm swim to reach the egg cell. Liverwort species may be either monoicous. In dioicous liverworts and male sex organs are borne on different and separate gametophyte plants. In monoicous liverworts, the two kinds of reproductive structures are borne on different branches of the same plant. In either case, the sperm must move from the antheridia where they are produced to the archegonium where the eggs are held; the sperm of liverworts is biflagellate, i.e. they have two tail-like flagellae that enable them to swim short distances, provided that at least a thin film of water is present.
Their journey may be assisted by the splashing of raindrops. In 2008, Japanese researchers discovered that some liverworts are able to fire sperm-containing water up to 15 cm in the air, enabling them to fertilize female plants growing more than a metre from the nearest male; when sperm reach the archegonia, fertilisation occurs, leading to the production of a diploid sporophyte. After fertilisation, the immature sporophyte within the archegonium develops three distinct regions: a foot, which both anchors the sporophyte in place and receives nutrients from its "mother" plant, a spherical or ellipsoidal capsule, inside which the spores will be produced for dispersing to new locations, a seta which lies between the other two
