BRÝØPHÝTËS (BRÝØLØGÝ)

Commonly growing in moist shaded areas in the hills.

They are non-vascular terrestrial plants in which diploid sporophyte lives

as a parasite on an independent haploid gametophyte.

They are called amphibians of the plant kingdom because they can live

in soil but need water for sexual reproduction.

Their body is more differentiated than that of algae. It is thallus-like

and prostrate or erect, and attached to the substratum by unicellular or

multicellular rhizoids.
