32.1 Reproductive Development and Structure - OpenStax
2023330 · The 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.
