prothallus is independent from sporophyte
A gametophyte is the plant that produces gametes. The fern gametophyte is a small, bisexual, heart- shaped plant called a prothallus. Sporophyte is the asexual and usually diploid phase that produces spores from which the gametophyte arises. A fern gametophyte prothallus is independent from sporophyte.
