Quiz on Bryophytes

The bryophyte includes the simplest and primitive plants. It occupies a position in between algae and pteridophytes. The group consists of about 960 genera over 25, 000 species, and occurring worldwide distribution. Bryophytes are first amongst land plants which occur in damp and shady habitats. Dominant phase in bryophytes is free living thalloid gametophyte. Nutritionally, the plant body is independent and is the conspicuous phase of the life cycle. The reproduce by vegetative and sexual methods. All bryophytes exhibit heteromorphic alternations of generations i.e., the individuals of the each generation are dissimilar. Read more>>
