bryophytes move nutrients through diffusion and osmosis so they have to be
near water to survive

Gametophyte


Question: Can bryophyte sporophytes and gametophytes live
indepedently? ⼀Answer: No. Sporophyte is physiologically dependent on
the gametophyte.

beneficial or paristic relationship. (plants growing on a tall tree). benefits are
indirect.

mutually beneficial, only beneficial to one.


Question: Main characteristics of liverworts ⼀Answer: no true stomata,
rhizoids, elaters, green- flat like gametophyte, sporophyte remains attached
to the larger gametophyte, can reproduce sexually or asexually, no internal
water conduction; differ from other bryophytes in the fact that they do not
have a true stomata and other bryophytes do
