A gametophyte is one of the two alternating multicellular phases in the life cycles of plants and algae. It is a haploid multicellular organism that develops from a haploid spore that has one set of chromosomes. The gametophyte is the sexual phase in the life cycle of plants and algae. It develops sex organs that produce gametes, haploid sex cells that participate in fertilization to form a diploid zygote which … WebGametophytic apomixis (Stebbins, 1950) is a common term for all types of apomixis where the maternal seed embryo develops from the egg cell of a well-developed embryo sac, without fertilization. Gametophytic apomicts are further divided into aposporous and diplosporous species according to the cell that gives rise to the embryo sac (Fig. 1).
