How many pollen grains will be formed after meiotic division in 10 microspores mother cells?

Options

A. 10
B. 20
C. 40
D. 80

Explanation

To solve the question of how many pollen grains will be formed after meiotic division in 10 microspore mother cells, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Microspore Mother Cell**:
- Each microspore mother cell (also known as microsporocyte) is a diploid cell that undergoes meiosis to produce microspores.

2. **Meiosis Process**:
- During meiosis, one microspore mother cell divides to produce four haploid microspores. This is a key point because it indicates that each mother cell contributes four pollen grains.

3. **Calculate for Multiple Cells**:
- If one microspore mother cell produces four pollen grains, then for 10 microspore mother cells, we can use multiplication to find the total number of pollen grains.
- Calculation:
\[ \text{Total pollen grains} = \text{Number of microspore mother cells} \times \text{Pollen grains per mother cell} \]
\[ \text{Total pollen grains} = 10 \times 4 = 40 \]

4. **Conclusion**:
- Therefore, after meiotic division in 10 microspore mother cells, a total of 40 pollen grains will be formed.

### Final Answer:
- The total number of pollen grains formed after meiotic division in 10 microspore mother cells is **40**.
