WebThe gametophyte refers to all organs and tissues that are a part of the haploid generation. There are two different developmental stages of the gametophyte: the protonema, and the gametophore. The protonema is … WebThe haploid gametophyte phase lasts longer or dominates the diploid saprophytic phase between these two alternations of generations. Heterosporous bryophytes hold two types of spores that develop gametophytes, in which one spore develops a male gametophyte, and the other develops a female gametophyte.
