The Marchantiophyta (/ m ɑːr ˌ k æ n t i ˈ ɒ f ə t ə,-oʊ ˈ f aɪ t ə / ⓘ) are a division of non-vascular land plants commonly 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.
An example of moss (Bryophyta) on the forest floor in Broken Bow, Oklahoma. Bryophytes (/ ˈ b r aɪ. ə ˌ f aɪ t s /) [2] are a group of land plants (embryophytes), sometimes treated as a taxonomic division, that contains three groups of non-vascular land plants: the liverworts, hornworts, and mosses (Bryophyta sensu lato). [3]
Some liverworts, such as Marchantia, have a cuticle, and the sporophytes of mosses have both cuticles and stomata, which were important in the evolution of land plants. [ 3 ] All land plants have a life cycle with an alternation of generations between a diploid sporophyte and a haploid gametophyte , but in all non-vascular land plants, the ...
Bryology (from Greek bryon, a moss, a liverwort) is the branch of botany concerned with the scientific study of bryophytes (mosses, liverworts, and hornworts). Bryologists are people who have an active interest in observing, recording, classifying or researching bryophytes. [1]
Chloroplasts (green discs) and accumulated starch granules in cells of Bryum capillare. Botanically, mosses are non-vascular plants in the land plant division Bryophyta. They are usually small (a few centimeters tall) herbaceous (non-woody) plants that absorb water and nutrients mainly through their leaves and harvest carbon dioxide and sunlight to create food by photosynthesis.
Dawsonia, the tallest moss in the world, can grow to 50 cm (20 in) in height. Mosses are commonly confused with hornworts , liverworts and lichens . [ 2 ] Mosses were formerly grouped with the hornworts and liverworts as "non-vascular" plants in the division " bryophytes ", all of them having the haploid gametophyte generation as the dominant ...
Liverworts (Hepaticae) are non-vascular plants with a bryophyte life cycle in which the gametophyte is the dominant generation. The study of mosses and liverworts is called bryology . The main article for this category is Marchantiophyta .
Marchantia polymorpha grows on shaded moist soil and rocks in damp habitats such as the banks of streams and pools, bogs, fens and dune slacks. [1] While most varieties grow on moist substrates, Marchantia polymorpha var. aquatica is semi-aquatic and is often found invading marshes, as well as small ponds that do not have a consistent water table.
