Which plants are Gametophyte dominant?
Which plants are Gametophyte dominant? Over the course of evolution, the gametophyte stage has become progressively reduced. Thus, the gametophyte stage is dominant in the more primitive (nonvascular) plants (bryophytes), whereas the sporophyte is the dominant phase in the life cycle of higher (i.e., vascular) plants. What is the basic difference between a Sporophyte and […]
