Seedless Plants Mosses and Other Bryophytes Write True if false 1. Mosses and their relatives belong to a group called Bryophytes 2. Bryophytes stay small because they lack true vascular tissue. 3. The gametophyte is the dominant stage of bryophytes. 4. Bryophytes must live in places where there water for at least part of the year because, for fertilization to occur, eggs must swim. ______________5. A fern is a seedless vascular plant 6.
