_______of the pollen grain divides to form two male gametes.

Options

A. Vegetative cell
B. Generative cell
C. Microspore mother cell
D. None of these

Explanation

To answer the question, we need to identify which part of the pollen grain divides to form two male gametes. Here’s a step-by-step solution:

1. **Understanding Pollen Grain Structure**: The pollen grain consists of two main types of cells - the vegetative cell and the generative cell. The vegetative cell is larger and primarily responsible for providing nutrients, while the generative cell is smaller.

2. **Role of Generative Cell**: The generative cell is crucial in the formation of male gametes. It undergoes division to produce two male gametes.

3. **Process of Division**: The generative cell divides through a process called mitosis (not meiosis, as mentioned in the video), resulting in the formation of two male gametes.

4. **Conclusion**: Therefore, the correct answer to the question is that the "generative cell of the pollen grain divides to form two male gametes."

**Final Answer**: Generative cell
