From one pollen mother cell, how many male gametes can be produced maximally?

Options

A. 2
B. 4
C. 6
D. 8

Answer

To determine how many male gametes can be produced from one pollen mother cell, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Type of Cell**:
- A pollen mother cell (PMC) is a diploid cell (2n) that undergoes meiosis to produce male gametes.

2. **Understand the Process of Meiosis**:
- Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four haploid cells from one diploid cell.

3. **Calculate the Number of Male Gametes**:
- From one diploid pollen mother cell, meiosis will produce four haploid cells. Each of these haploid cells can develop into a male gamete (pollen grain).
- Therefore, the maximum number of male gametes produced from one pollen mother cell is **4**.

4. **Consider Additional Factors**:
- In some cases, there can be variations in the development of pollen grains, but the maximum number remains four as each haploid cell corresponds to one male gamete.

5. **Conclusion**:
- The answer to the question is that from one pollen mother cell, a maximum of **4 male gametes** can be produced.

### Final Answer:
From one pollen mother cell, a maximum of **4 male gametes** can be produced.
