What would be number of chromosomes in aleurone layer if megaspore mother cell contains 10 chromocomes

Options

A. 10
B. 20
C. 15
D. None of the above.

Answer

To determine the number of chromosomes in the aleurone layer when the megaspore mother cell contains 10 chromosomes, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Chromosome Number in the Megaspore Mother Cell**:
- The megaspore mother cell is diploid (2n). Given that it contains 10 chromosomes, we can write:
\[ 2n = 10 \]

2. **Calculate the Haploid Number (n)**:
- To find the haploid number (n), we divide the diploid number by 2:
\[ n = \frac{2n}{2} = \frac{10}{2} = 5 \]

3. **Determine the Chromosome Number in the Aleurone Layer**:
- The aleurone layer is triploid (3n). Therefore, we can calculate the number of chromosomes in the aleurone layer by multiplying the haploid number by 3:
\[ 3n = 3 \times 5 = 15 \]

4. **Conclusion**:
- The number of chromosomes in the aleurone layer is 15.

### Final Answer:
The number of chromosomes in the aleurone layer is **15**.
