Definition
Homosporous describes plants that produce only one type of spore. This single type of spore develops into a bisexual gametophyte, which produces both sperm and egg cells. This is a more primitive form of plant reproduction compared to heterospory. Homosporous plants include most ferns and some clubmosses. They rely on environmental cues to control fertilization. Think of it as plant reproduction where each spore is both "male" and "female."
