List of Viridiplantae divisions

This post is a list of Viridiplantae divisions. There are 12 divisions listed below chronologically. Source: Wikipedia


1. Anthocerotophyta - Hornworts

"The plant body of a hornwort is a haploid gametophyte stage. This stage usually grows as a thin rosette or ribbon-like thallus between one and five centimeters in diameter." (Wikipedia: Hornwort, 8.9.21 UTC 02:43)


2. Bryophyta - Mosses

"Mosses typically form dense green clumps or mats, often in damp or shady locations... Mosses do not have seeds and after fertilization develop sporophytes with unbranched stalks topped with single capsules containing spores." (Wikipedia: Moss, 8.14.21 UTC 02:40)


3. Charophyta - Green algae

"Charophyta is a group of freshwater green algae... The charophytes and embryophytes share several traits that distinguish them from the chlorophytes, such as the presence of certain enzymes, ...lateral flagella (when present) and, in many species, the use of phragmoplasts in mitosis." (Wikipedia: Charophyta, 7.06.21 UTC 04:43)


4. Chlorophyta - Green algae

"Chlorophyta is a taxon of green algae informally called chlorophytes... All members of the clade have motile flagellated swimming cells. While most species live in freshwater habitats and a large number in marine habitats, other species are adapted to a wide range of land environments." (Wikipedia: Chlorophyta, 6.13.21 UTC 14:38)


5. Cycadophyta - Cycads

"[Cycads] typically have a stout and woody (ligneous trunk with a crown of large, hard and stiff, evergreen leaves... Cycads vary in size from having trucks only a few centimeters to several meters tall." (Wikipedia: Cycad, 7.9.21 UTC 17:45)


6. Ginkgophyta - Ginkgo

"Ginkgoales is a gymnosperm order containing only one extant species: Ginkgo biloba, the ginkgo tree... The distinctive shape of the modern Ginkgo biloba gives the impression of a very narrow leaf morphology, but the group [Ginkgo] is varied and diverse." (Wikipedia: Ginkgoales, 6.10.21 UTC 17:55)


7. Gnetophyta

"The primary difference between gnetophytes and other gymnosperms is the presence of vessel elements, a system of conduits that transport water within the plant, similar to those found in flowering plants." (Wikipedia: Gnetophyta, 8.2.21 UTC 01:58)


8. Lycopodiophyta - Clubmosses

"[Lycopodiopsida] have dichotomously branching stems bearing simples leaves called microphylls and reproduce by means of spores borne in sporangia on the sides of the stems at the bases of the leaves." (Wikipedia: Lycopodiopsida, 6.9.21 UTC 18:31)


9. Magnoliophyta - Flowering plants

"[Flowers] are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds and the production of fruits that contain the seed." (Wikipedia: Flowering plant, 8.13.21 UTC 04:34)


10. Marchantiophyta - Liverworts

"Some of the more familiar species grow as flattened leafless thallus, but most species are leafy with a form very much like a flattened moss... Liverworts are typically small, usually from 2-20 mm wide with individual plants less than 10 cm long... However certain species may cover large patches of ground..." (Wikipedia: Marchantiophyta, 8.9.21 UTC 03:45)


11. Pinophyta - Conifers

"Conifers are a group of cone-bearing seed plants, a subset of gymnosperms... The great majority are trees, though a few are shrubs. Examples include cedars, Douglas-fires, cypresses, firs, junipers, kauri, larches, pines, hemlocks, redwoods, spruces and yews." (Wikipedia: Conifer, 8.10.21 UTC 15:04)


12. Polypodiophyta - Ferns

"A fern is a member of a group of vascular plants that reproduce via spores and have neither seeds nor flowers... Ferns have complex leaves called megaphylls..." (Wikipedia: Fern, 8.15.21 UTC 11:38)
