Sporogenesis and gametogenesis are important events before the act of fertilization. The formation of megaspore is megasporogenesis, and the formation of microspore is microsporogenesis. The fusion of male and female gametes is known as amphimixis or syngamy. The generative cell in pollen divides mitotically to form male gametes, and the process is called gametogenesis/microgametogenesis.
