WitrynaThe male gametophyte develops and reaches maturity in an immature anther. In a plant’s male reproductive organs, development of pollen takes place in a structure known as the microsporangium ( Figure 32.6 ). The microsporangia, which are usually bilobed, are pollen sacs in which the microspores develop into pollen grains. WitrynaWhen this happens, the microspore is transformed to an immature, endosporic male gametophyte or pollen grain (Chapter 5). The generative cell divides one time, producing two sperm cells (Figure 6.8A).
