Did you know?
Sporophytes are diploid plants that use meiosis to produce spores. These spores are haploid cells that grow into haploid gametophytes. Megaspores grow into female gametophytes, and microspores grow into male gametophytes. Meiosis occurs in the sporangium of a sporophyte and results in haploid spores. … See more In all plants and some algae, an alteration of generations exists in which the species have diploid and haploid phases. Sexual reproduction results in gametes that combine two cells … See more Gametophytes are haploid plants that use mitosis to make haploid gametes. These gametes are female in the form of an ovum (egg) or male in the form of sperm. Gametophytes … See more Scientists continue to learn more alternating generations in plants.
