A sporangium is an enclosure in which spores are formed. It can be composed of a single cell or can be multicellular. Virtually all plants, fungi, and many other groups form sporangia at some point in

Mosses are small, non-vascular flowerless plants in the taxonomic division Bryophyta sensu stricto. Bryophyta sensu lato may also refer to the parent group, bryophytes, which comprises liverworts, mos

…into diploid nuclei. When conditions improve, the zygosporangium germinates, undergoes meiosis and produces a sporangium, which releases spores. In mosses, liverworts and hornworts, an unbranched sporophyte produces a single sporangium, which may be quite complex morphologically. Most non-vascular plants…
