Detailed explanation-1: -Mosses are non-vascular plants with about 12, 000 species classified in the Bryophyta. Unlike vascular plants, mosses lack xylem and absorb water and nutrients mainly through their leaves.

Detailed explanation-2: -They are low-growing forms of plants that are found growing in moist habitats. Examples of nonvascular plants include mosses or Bryophytes, liverworts or Hepaticophyta, and hornworts or Anthocerophyta.

Detailed explanation-3: -There are three divisions of nonvascular plants-mosses (Division Bryophyta), liverworts (Division Hepatophyta, named for the resemblance of some to small livers), and hornworts (Division Anthocerotophyta, named for the horn-like appearance of their reproductive structures).

Detailed explanation-4: -They lack true roots, stems, or leaves. They are called non-vascular plants because of the absence of vascular tissues (xylem and phloem) that functions for the conduction of food, water, and minerals.

Detailed explanation-5: -The Bryophyta s.l. are a proposed taxonomic division containing three groups of non-vascular land plants (embryophytes): the liverworts, hornworts and mosses.
