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, like other bryophytes, have a gametophyte-dominant life cycle, with the sporophyte dependent on the gametophyte ...
Mosses are small, non-vascular flowerless plants in the taxonomic division Bryophyta (/ b r aɪ ˈ ɒ f ə t ə /, [3] / ˌ b r aɪ. ə ˈ f aɪ t ə /) sensu stricto.Bryophyta (sensu lato, Schimp. 1879 [4]) may also refer to the parent group bryophytes, which comprise liverworts, mosses, and hornworts. [5]
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. [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 ...
The Setaphyta are a clade within the Bryophyta which includes Marchantiophytina (liverworts) and Bryophytina (mosses). Anthocerotophytina (hornworts) are excluded. [1] [2] A 2018 study found through molecular sequencing that liverworts are more closely related to mosses than hornworts, with the implication that liverworts were not among the first species to colonize land.
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.
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]
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 phase of the life cycle .
