WebJun 8, 2024 · Inside the anthers’ microsporangia, male gametophytes divide by meiosis to generate haploid microspores, which, in turn, undergo mitosis and give rise to pollen grains. Each pollen grain contains two cells: one generative cell that will divide into two sperm and a second cell that will become the pollen tube cell. WebMay 3, 2024 · Microgametophytes are formed within the microsporangia of the microstrobilus, or pollen cone. These structures are all diploid.
