Question

what are the disadvantages of brayophyta?​

Answer 1

Answer;

The body tissue of the gametophyte (the dominant part of the life cycle in bryophytes) lacks formal xylem and phloem conducting tissue like that exhibited by the vascular plant groups. Thus bryophytes cannot grow up far from the substrate that is their source of water and mineral nutrients. For example, a tree-sized moss would be anatomically impossible due to the fact that it could not translocate water very far against the force of gravity.

Despite these seeming disadvantages compared to the vascular plants, the bryophytes are superabundant in many subarctic vegetation types and plant communities. In fact, there are very good reasons to believe that mosses play the defining role in many areas of Denali’s landscape. The deep layer of moss that forms in the floor of our boreal forests and cotton-grass dominated bogs has profound influences on the physical and biological characteristics of these sites.
