Meiosis is best seen in

Options

A. Microsporangium
B. Pollen grain
C. Gamete
D. Anther wall

Answer

To answer the question "Meiosis is best seen in which of the following: Microsporangium, pollen grain, gamete, and anther wall?", we will analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding Meiosis**:
- Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four haploid cells from one diploid cell. This process is crucial for sexual reproduction as it produces gametes.

2. **Analyzing the Options**:
- **Microsporangium**: This is a structure in plants where microspores are produced. The microspore mother cells within the microsporangium undergo meiosis to produce haploid microspores, which eventually develop into pollen grains.
- **Pollen Grain**: Pollen grains are the male gametes of plants. They are already haploid and result from the process of meiosis, so meiosis cannot be observed in pollen grains themselves.
- **Gamete**: Similar to pollen grains, gametes (both male and female) are haploid cells that result from meiosis. Therefore, meiosis is not observed in gametes.
- **Anther Wall**: The anther wall is part of the flower structure that holds the microsporangia. Meiosis does not occur in the anther wall itself.

3. **Conclusion**:
- The only option where meiosis occurs is the **Microsporangium**, as it contains microspore mother cells that undergo meiosis to produce haploid microspores. Therefore, the correct answer is **Microsporangium**.

### Final Answer:
Meiosis is best seen in **Microsporangium**.
