Plants which reproduce sexually also produce gametes. However, since plants have a life cycle involving alternation of diploid and haploid generations some differences exist. Plants use meiosis to produce spores that develop into multicellular haploid gametophytes which produce gametes by mitosis. The sperm are formed in an organ known as the antheridium and the egg cells in a flask-shaped organ called the archegonium. In flowering plants, the female gametophyte is produced i… Web15 Nov 2024 · Some may refer to them as “sex cells” or “reproductive cells.” For humans, the male gamete would be sperm cells and the female gamete would be egg cells. ...
