What is the main difference between the life cycles of members of phylum bryophyta and phylum pteridophyta? group of answer choices only members of phylum pteridophyta display alternation of generations. only members of phylum bryophyta possess flagellated sperm. in phylum bryophyta, the gametophyte generation reproduces sexually; whereas in phylum pteridophyta, the gametophyte generation reproduces asexually. in phylum bryophyta, the sporophyte generation is multicellular; whereas in phylum pteridophyta, the sporophyte generation is unicellular. in phylum bryophyta, the gametophyte generation is dominant; whereas in phylum pteridophyta, the sporophyte generation is dominant.

Phylum Bryophyta, the gametophyte generation is dominant; whereas in Phylum Pteridophyta, the sporophyte generation is dominant.

Explanation:

Bryophytes are the non-vascular plants with leafy gametophyte as the main plant body. It does not have a true stem, roots, and leaves. Sporophyte grows on the female gametophyte and is nutritionally dependent on the gametophyte. The sporophyte of mosses does not have an independent existence.

Phylum Pteridophyta includes ferns which are seedless vascular plants. Ferns have sporophyte as the main plant body with a rhizome, fronds (the leaves) and true roots. On the other hand, the gametophyte (prothallus) in ferns is a tiny and green structure that grows at the surface of the ground.

this is a good question! i'll do some research and come back when i have the answer!
