dominant sporophyte

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. Are flowering plants gametophyte dominant? The sporophyte is the
