Web1 Mar 2011 · While it is clear that in general multicellularity has evolved multiple times (i.e., among protistan groups), all candidate sister groups to the embryophytes are characterized by a haplobiontic life cycle in which the gametophyte is multicellular and dominant and the sporophyte generation is limited to a unicellular zygote. WebThe alternation of generations is an important concept in the evolution of plants. All land plants have alternation of generations. In mosses and their relatives (Bryophytes), the haploid gametophyte is the dominant generation, and the diploid sporophytes are sporangium-bearing stalks growing from the gametophytes. In ferns, the diploid …

WebA sporophyte is a term given to a diploid generation where the spores are produced by meiosis, while the gametophyte generation is haploid with the gametes being produced by mitosis. Spores provide a means of dispersal and give rise to the gametophyte generation while gametes (sperm and eggs) fuse and give rise to the sporophyte generation.
