Question

Which structure of an anther later develops into pollen sac ??

Answer 1

Answer:

microsporangium

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 5). The microsporangia, which are usually bi-lobed, are pollen sacs in which the microspores develop into pollen grains.
