(C) In heterosporous ferns,the megaspore germinates to form the female gametophyte.This female gametophyte is typically reduced in size and remains dependent on the parent sporophyte for nutrition.In many pteridophytes,the gametophyte is referred to as a $Prothallus$,which is a small,multicellular,free-living,mostly photosynthetic thalloid structure.Therefore,the female gametophyte in these plants is the $Prothallus$.
