Characteristics of bryophytes make them useful to the environment. Depending on the specific plant texture, bryophytes have been shown to help improve the water retention and air space within soil. [48] Bryophytes are used in pollution studies to indicate soil pollution (such as the presence of heavy metals), air pollution, and UV-B radiation. [48]
[11] [12] With the exception of the ancient group Takakiopsida, no known mosses form mycorrhiza, [13] but bryophilous fungi is widespread in moss and other bryophytes, where they live as saprotrophs, parasites, pathogens and mutualists, some of them endophytes. [14] Mosses differ from vascular plants in lacking water-bearing xylem tracheids or ...
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.

[citation needed] It was assumed that the gametophyte dominant phase seen in bryophytes used to be the ancestral condition in terrestrial plants, and that the sporophyte dominant stage in vascular plants was a derived trait. However, the gametophyte and sporophyte stages were probably equally independent from each other, and that the mosses and ...
Hypnales is the botanical name of an order of Bryophyta or leafy mosses.This group is sometimes called feather mosses, referring to their freely branched stems. [1] The order includes more than 40 families and more than 4,000 species, making them the largest order of mosses.
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]
While it is a common characteristic in mosses, B. argenteum was one of the first bryophytes experimentally determined to be desiccation tolerant. [ 4 ] Distribution and habitat
The gametophyte is the first and dominant phase of two alternating phases in a bryophyte's life cycle. This part of the life cycle consists of protonema (the preliminary stage where the propagule develops green thread-like filaments), the rhizoids (filaments growing beneath the bryophyte that help anchor the bryophyte to its substratum), the stem, the leaves, its reproductive structure ...
