Answers
General Characteristics of Bryophytes:
Plants occur in damp and shaded areas. The plant body is thallus like, i.e. prostrate or erect. It is attached to the substratum by rhizoids, which are unicellular or multicellular. They have a root-like, stem-like and leaf-like structure and lack true vegetative structure.
The gametophytic phase is predominant and ecologically
persistent,i.e.,green,independent and long-lived.
The sporophytic phase is very short-lived,and completely
dependent upon the gametophyte.
The gametophytic plant body is either thalloid or differentiated
into the erect axis and lateral appendages.
Roots are absent in bryophytes, rhizoids perform the function of
roots. Rhizoids are either unicellular & unbranched or
multicellular & branched.
