The life cycle of ferns is different from other land plants as both the gametophyte and the sporophyte phases are free living. This interactive illustrates the alternation of generations in ferns.ametophyte (prothallus). The prothallus is the fern gametophyte. It is a green, photosynthetic structure that is one cell thick, usually heart or kidney shaped, 3â10 mm long and 2â8 mm broad. It is very difficult to find in the bush as it is so tiny.
Unlike many other vascular plants, ferns do not have seeds or flowers but instead reproduce through spores.
