How does the pollen mother cell develop into a mature pollen grain? Illustrate the stages with labelled diagrams.

Explanation

**Step-by-Step Solution:**

1. **Start with the Pollen Mother Cell (Microspore Mother Cell):**
- The process begins with the pollen mother cell, also known as the microspore mother cell, which is diploid (2n).
- **Diagram:** Draw a large circle labeled "Pollen Mother Cell (Microspore Mother Cell) - 2n".

2. **Meiosis I:**
- The pollen mother cell undergoes meiosis I, resulting in two haploid cells.
