The opposite is true for tracheophytes (vascular plants), in which the diploid generation is dominant and the sporophyte comprises the main plant. Bryophyte Generations
Gametophytes In Plants. Let's look at some examples of gametophytes in different groups of plants. In nonvascular plants, like mosses, the gametophyte generation is the dominant generation. This means that the gametophyte is larger in size and lives longer than the sporophyte generation.
