Answer: gametophyte produces motile gamates known as spermatozoa (male gamate) and non motile produces female gamate known as ovum. And sporophyte produces spores
Explanation:
During gametophyte water is essential for fertilization between spermatozoa and ovum, the ovum will later developed into Zygote, which latter grows to gametophyte and latter sporophyte which produces spores.these spores are dispersed,when they fall on suitable environment, the develop into gametophyte.examples of organism that undergo alternation of generation are liverwort, moss, and fern
