Web7 Jul 2024 · In 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 generation is dominant and the sporophyte comprises the main plant.
WebAlternation of Generation in Bryophytes. We can describe the alternation of generation life cycle in plants starting with a diploid organism, or sporophyte. This is the first stage, or generation one, in the life cycle. In most plants, this is the phase we recognize as the plants' bodies.
