Haploid Vs. Diploid Cells (All Info) – All The Differences

Gametogenesis is a biological process by which diploid or haploid precursor cells undergo cell division and differentiation to form mature haploid gametes. Depending on the biological life cycle of the organism, gametogenesis occurs by meiotic division of diploid gametocytes into various gametes, or by mitosis. For example, plants produce gametes through mitosis in gametophytes. The gamet… WebThe haploid nucleus inside each microspore divides into a tube nucleus and generative nucleus before it becomes a mature pollen grain. The pollen grains are released at this binucleate stage and are carried by wind, insects or water to the receptive female part of a flower called the stigma.
