Gametophytes are the haploid form in the life cycle of land plant and algae. It is produced from the meiotic division of sporophytes. They can be either male (produce sperm) or female (produce eggs). In bryophytes: mosses, liverworts, and hornworts, the gametophyte is the dominant part of the life cycle. Sporophytes grow out of the gametophyte, and the gametophyte is the most familiar form. In vascular plants, the gametophyte is not the dominant part of the life cycle and can be from a few cells to a few thousand cells. A trend of shorter living gametophytes and more adaptation to land exists.
