In flowering plants the generative cell of pollen grain divides mitoticaly to give rise to the

Options

A. 2 male gametes
B. 3 male gametes
C. 1 male gamete
D. 4 male gametes

Answer

**Step-by-Step Solution:**

1. **Understanding the Structure of Pollen Grain**:
- The pollen grain in flowering plants (angiosperms) is composed of two layers: the outer layer called the exine and the inner layer called the intine.
- The exine is hard and made of sporopollenin, while the intine is soft and made of pectocellulose.

2. **Identifying the Cells in Pollen Grain**:
- Inside the intine, there are two types of cells: the vegetative cell and the generative cell.
- The vegetative cell is larger and contains its own nucleus.

3. **Role of the Generative Cell**:
- The generative cell is smaller and located within the cytoplasm of the vegetative cell.
- This generative cell is crucial for the formation of male gametes.

4. **Mitosis of the Generative Cell**:
- The generative cell undergoes mitotic division, which means it replicates its nucleus and divides.
- This division results in the formation of two male gametes.

5. **Conclusion**:
- Therefore, the generative cell of the pollen grain divides mitotically to give rise to **two male gametes**.

**Final Answer**: The generative cell of pollen grain divides mitotically to give rise to **two male gametes**.
