The prothallus, a small gametophyte stage in pteridophytes, plays a crucial role after fertilization by providing anchorage and a food supply to the developing sporophyte. Following fertilization, the prothallus remains attached to the sporophyte, supporting its growth. Over time, the prothallus may degenerate as the sporophyte matures and becomes independent. This relationship highlights the prothallus's importance in the early stages of pteridophyte development.

It serves as anchorage and food supply to the parasitic sporophytejaumzaum said:The prothallus is the small gamethophyte stage in pteridophytes. What happens with it after the fertilization and growth of the sporophyte?
It stay attached? It degenerates?
