The cell of endosperm have 24 chromosomes. What will be the number of chromosomes in the gametes?

Options

A. 8
B. 16
C. 72
D. 24

Answer

To determine the number of chromosomes in the gametes when the endosperm has 24 chromosomes, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Chromosome Count in Endosperm**:
- The endosperm is a triploid tissue in flowering plants, which means it has three sets of chromosomes. In this case, it is given that the endosperm has 24 chromosomes.

2. **Determine the Diploid Number**:
- Since the endosperm is triploid (3n), we can find the diploid number (2n) by dividing the number of chromosomes in the endosperm by 3.
- Calculation:
\[ 2n = \frac{24}{3} = 8 \]

3. **Identify the Haploid Number**:
- The gametes (sperm and egg cells) are haploid (n), which means they contain half the number of chromosomes compared to the diploid number.
- Calculation:
\[ n = \frac{2n}{2} = \frac{8}{2} = 4 \]

4. **Conclusion**:
- Therefore, the number of chromosomes in the gametes is 8.

### Final Answer:
The number of chromosomes in the gametes is **8**.
