Detailed explanation-1: -Larger and to have larger sex organs.
Detailed explanation-2: -The phyllids of bryophytes generally lack vascular tissue and are thus not analogous to the true leaves of vascular plants. Most gametophytes are green, and all except the gametophyte of the liverwort Cryptothallus have chlorophyll.
Detailed explanation-3: -In nonvascular plants: gametophyte is larger, longer-lived, and more self-sufficient than the sporophyte. gametophyte generation is photosynthetic.
Detailed explanation-4: -After fertilization, the diploid sporophyte grows out of the archegonium on the gametophyte, but unlike the nonvascular plants, in these groups the sporophyte grows much larger than the gametophyte and eventually becomes the free-living, dominant form of the life cycle.
Detailed explanation-5: -The smallest and least complex gametophytes are those of the flowering plants. The male gametophyte is the two-or three-celled pollen grain that is released from the anther, and the female gametophyte is the seven-celled embryo sac that is located in the base of the pistil of the flower.
