What is the role of mitosis in the growth of a plant? Like other multicellular organisms, plants grow through a combination of cell growth and cell division. WebNov 25, 2024 · In animals, meiosis produces sperm and egg, but in plants, meiosis occurs to produce the gametophyte. The gametophyte is already haploid, so it produces sperm and egg by mitosis. The gametes merge, producing cells called zygotes that contain the same number of chromosomes as the parent plant — that is, the zygotes are diploid.
