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.
Non-vascular plants are often among the first species to move into new and inhospitable territories, along with prokaryotes and protists, and thus function as pioneer species. [ citation needed ] Mosses and leafy liverworts have structures called phyllids that resemble leaves , but only consist of single sheets of cells with no internal air ...
Marchantia, an example of a liverwort (Marchantiophyta) An example of moss (Bryophyta) on the forest floor in Broken Bow, Oklahoma. Bryophytes (/ ˈ b r aɪ. ə ˌ f aɪ t s /) [1] 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.

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.
Like all bryophyte species, Hypnodendron species are non-vascular, meaning the vasculature or ducts within the tissues in which water, nutrients and sugars are transported around the plant are non-existent. [3] Bryophytes also lack true roots but are anchored to the substrate by rhizoids. Unlike vascular plants that use their roots to exchange ...
Non-vascular plants , with their different evolutionary background, tend to have separate terminology. Although plant morphology (the external form) is integrated with plant anatomy (the internal form), the former became the basis of the taxonomic description of plants that exists today, due to the few tools required to observe.
The Bryopsida constitute the largest class of mosses, containing 95% of all moss species.It consists of approximately 11,500 species, common throughout the whole world. The group is distinguished by having spore capsules with teeth that are arthrodontous; the teeth are separate from each other and jointed at the base where they attach to the opening of the capsule.

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]
