Websporophyte is dominant in higher plants. (see figure 19.2). Evolutionary trends in plants. 1. diploid phase is dominant in higher plants. 2. higher plants are less dependent on liquid water. 3. dispersal). The bryophytes: Simple land plants. Examples WebIn bryophytes (mosses and liverworts), the dominant generation is haploid, so that the gametophyte comprises what we think of as the main plant. The opposite is true for tracheophytes (vascular plants), in which the diploid …

Life Cycle - in a nutshell - bryophyte
Like all land plants (embryophytes), bryophytes have life cycles with alternation of generations. In each cycle, a haploid gametophyte, each of whose cells contains a fixed number of unpaired chromosomes, alternates with a diploid sporophyte, whose cell contain two sets of paired chromosomes. Gametophytes produce haploid sperm and eggs which fuse to form diploid zygotes that grow into spor… WebIn the life cycle of bryophytes sporophytes are the dominant stage and are.
