A plant alternates between a multicellular
diploid (2n) sporophyte and a
haploid (n) gametophyte generation.
diploidsporophyte with reproductive structures.
meiosisto produce microspores.
meiosisto yield 4 megaspores each.
mitosisto form multicellular male gametophytes (pollen grains), which contain sperm cells.
mitosisto form a multicellular female gametophyte (embryo sac), which contains an egg cell in an ovule.
mitosisto produce the sporophyte.
