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 ...
Protonemata are characteristic of all mosses, are present in some liverworts under certain conditions [2] but are absent from hornworts. [ citation needed ] The protonemata are composed of two cell types: chloronemata , which form upon germination of the spore, and caulonemata , which later differentiate from chloronemata under the influence of ...
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]
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.
From a distance, Takakia looks like a typical layer of moss or green algae on the rock where it grows. On closer inspection, tiny shoots of Takakia grow from a turf of slender, creeping rhizomes . The green shoots which grow up from the turf are seldom taller than 1 cm, and bear an irregular arrangement of short, finger-like leaves (1 mm long).
A bryophilous lichen is one that grows on a bryophyte – that is, on a moss or liverwort. [1] Those which grow on mosses are known as muscicolous lichens, [2] while those which grow on liverworts are called hepaticolous lichens. [3] Muscicolous derives from the Latin muscus meaning moss, [4] while the suffix colous means "living or growing in ...
