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

Explanation

### Step-by-Step Solution

1. **Definition of Microsporogenesis**: Microsporogenesis is the process of formation and differentiation of pollen grains from the microspore mother cell (MMC). This process occurs in the pollen sacs of the anther.

2. **Cell Division in Microsporogenesis**: The type of cell division that occurs during microsporogenesis is meiosis. The microspore mother cell, which is diploid, undergoes meiosis to produce haploid microspores.

3. **Outcome of Microsporogenesis**: At the end of microsporogenesis, four functional pollen grains are formed from each microspore mother cell.
