Pollen tube develops from

Options

A. Generative cell
B. Male gametes
C. Vegetative cell
D. Vegetative nucleus

Answer

To determine from which part the pollen tube develops, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Pollen Structure**: Pollen grains are produced in the anthers of flowering plants and contain two types of cells: vegetative cells and generative cells.

2. **Identifying Cell Functions**:
- **Generative Cells**: These cells divide to form male gametes (sperm cells).
- **Vegetative Cells**: These cells are responsible for the growth of the pollen tube and provide nourishment.

3. **Pollen Tube Development**: When pollen grains land on a compatible stigma, the vegetative cell is the one that develops into the pollen tube. The generative cell does not contribute to the formation of the pollen tube.

4. **Conclusion**: Therefore, the pollen tube develops specifically from the vegetative cells of the pollen grain.

5. **Final Answer**: The correct answer is that the pollen tube develops from **vegetative cells**.
