Solution:

One microspore mother cell undergoes meiosis to form four microspores / pollen grains. All these pollen grains are functional and they further undergo mitosis. Pollen grain is generally released in 2 celled stage in angiosperms. The two cells are generative and vegetative cell. The generative cell later undergoes division and forms two male gametes. The mature fully developed, fertilization ready pollen grain has 3 nuclei in it after the division of generative cell.
