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 American Bryological and Lichenological Society is an organization devoted to the scientific study of all aspects of the biology of bryophytes and lichen-forming fungi and is one of the nation's oldest botanical organizations.
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.
The membrane structure in bryophytes is not affected by desiccation, but protein synthesis is strongly affected. It was found that decline in proteins was much greater in drought sensitive plants. Dehydrins and rehydrins are LEA proteins, or proteins involved in protecting plants against drought and other environmental stresses and protecting ...
In all bryophytes, the primary plants are the haploid gametophytes, with the only diploid portion being the attached sporophyte, consisting of a stalk and sporangium. Because these plants lack lignified water-conducting tissues, they cannot become as tall as most vascular plants. Algae, especially green algae. The algae consist of several ...
Historically, Hypnum mosses were used to stuff bedding because they were falsely believed to have sleep-inducing properties. [2] [3] Hypnum curvifolium, commonly known as "sheet moss", is used by some florists. [6] The CityTree air filter, present in many European cities, uses Hypnum to capture and consume pollutants. [7]
While it is a common characteristic in mosses, B. argenteum was one of the first bryophytes experimentally determined to be desiccation tolerant. [4]
Sphagnum, like all other land plants, has an alternation of generations; like other bryophytes, the haploid gametophyte generation is dominant and persistent. Unlike other mosses, the long-lived gametophytes do not rely upon rhizoids to assist in water uptake. [4]
