Options

A. Pollen grain
B. Male gamete
C. Female gamete
D. Both B and C.

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question states that plant cells possess a cell wall, but this wall is absent in certain structures. We need to identify which of the given options does not have a cell wall.

2. **Analyzing the Options**:
- **Pollen Grain**: Pollen grains are the male gametes of flowering plants. They have a tough outer layer called sporopollenin, which is a protective covering. Therefore, pollen grains do have a wall, making this option incorrect.

- **Male Gamete**: Male gametes in plants are formed in the antheridia. They are motile and do not have a cell wall surrounding them. This indicates that male gametes do not possess a cell wall, making this option correct.

- **Female Gamete**: Female gametes are located in the archegonium and are non-motile. Similar to male gametes, female gametes do not have a cell wall surrounding them. This also indicates that female gametes do not possess a cell wall, making this option correct as well.

3. **Conclusion**: Since both male and female gametes do not have a cell wall, the correct answer to the question is **both B and C**.

4. **Final Answer**: The answer is **both B and C** (male gamete and female gamete).
