The germ pores on the pollen grains are found on the

Options

A. Exine only
B. Intine only
C. Both exine and intine
D. Vegetative cell

Answer

To solve the question regarding the location of germ pores on pollen grains, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Pollen Structure**:
- Pollen grains are the male gametes of flowering plants and consist of two main layers: the exine (outer layer) and the intine (inner layer).

2. **Identifying the Germ Pores**:
- Germ pores are specific regions on the pollen grain where the exine layer is absent or thinner. This allows for the emergence of the germ tube during the process of pollination.

3. **Examining the Options**:
- **Option A: Exine only** - This suggests that germ pores are found only on the exine.
- **Option B: Intine only** - This suggests that germ pores are found only on the intine.
- **Option C: Both Exine and Intine** - This suggests that germ pores are found on both layers.
- **Option D: Vegetative cells** - This suggests that germ pores are found on vegetative cells, which is incorrect.

4. **Determining the Correct Answer**:
- Since germ pores are specifically areas on the exine where it is absent, the correct answer is **Option A: Exine only**.

### Final Answer:
The germ pores on the pollen grains are found on the **Exine only**.
