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… Nettet28. mai 2024 · It is important that meiosis produces haploid gametes, rather than diploid gametes because it takes two gametes—one from each parent—to create a single offspring. These two gametes come together to form a single, diploid cell, called a zygote. Are gametes always haploid? Gametes are formed independently either from diploid … jenis swab
