The two cells at which pollen grains are discharged are

Options

A. Larger generative cell and smaller vegetative cell
B. Larger generative cell and smaller body cell
C. Smaller generative cell and larger body cell
D. Smaller generative cell and larger vegetative cell

Answer

To answer the question about the two cells present in pollen grains when they are discharged, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Pollen Grain Structure**:
- Pollen grains are the male gametophytes in flowering plants. They contain two main types of cells after undergoing mitosis.

2. **Cell Division in Pollen Grains**:
- When pollen grains mature, they undergo mitosis, resulting in the formation of two distinct cells within the pollen grain.

3. **Identifying the Two Cells**:
- The two cells formed are:
- **Generative Cell**: This cell is responsible for producing sperm cells during fertilization. It is smaller in size.
- **Vegetative Cell**: This cell is larger and provides support and nourishment to the generative cell. It also develops into the pollen tube during fertilization.

4. **Conclusion**:
- Therefore, the two cells at which pollen grains are discharged are the **smaller generative cell** and the **larger vegetative cell**.

### Final Answer:
The two cells at which pollen grains are discharged are the **smaller generative cell** and the **larger vegetative cell**.
