The Bryophyta
Hi viewers
Today we will discuss about the world of Bryophyta
Definition of Bryophyta
A division of nonflowering plants characterized by rhizoids rather than true roots and having little or no organized vascular tissue and showing alternation of generations between gamete-bearing forms and spore-bearing forms; comprises true mosses (Bryopsida) and liverworts (Hepaticopsida) and hornworts (Anthoceropsida)
PROPERTIES BRYOPHYTA
Autophytic nutrition.
Terrestrial
Aphibians among the Plant Kingdom because it needs water during the reproduction
Thallus body
Reserve food material is starch
Cell wall- cellulose
Sporophyte depends upon the gametophyte
Adult life starts with gametophyte
Chemotropism- occurs by synthesis of sucrose
Vascular tissue is absent
Eg. Any kind of moss
Q and A on Bryophyta
What are the main characters of Bryophyta? (3)
Ans. The main characters of Bryophyta:
a) Bryophyta is a kind of non-flowering, autophytic independent plant.

c) Conducting tissue systems (xylem and phloem) are absent. It...
