Differentiate between microsporogenesis and megasporogenesis. Which type of cell division occurs during these events? Name the structures formed at the end of these two events.

Explanation

Microsporogenesis:
1. It refers to the process of formation of microspores from a microspore mother cell.
2. It occurs in micro sporangia present in anther.
3. The microspores are arranged in a tetrad manner. Megasporogenesis :
1. It refers to the process of formation of megaspores from a megaspore mother cell. 2. It occurs in the nucleus part of the ovule.
3. Megaspores are arranged in a linear row. Meiosis occurs in both of the events.
- Microsporogenesis gives rise to microspores (Pollen grains), while megasporogenesis gives rise to megaspores.
