Sporogenesis

• Production of microspores and megaspores from micro and megaspore mother cells respectively after meiosis is known as sporogenesis.
• Microspores are produced in the anthers while the megaspores are formed in the ovules.

Gametogenesis

• The production of male and female gametes from the micro and megaspores respectively after mitosis is known as gametogenesis.

Important events involved during the process of seed formation are:

1. Microsporogenesis and microgametogenesis
2. Megasporogenesis and megagametogenesis
3. Pollination and fertilization
