If an endosperm cell of an angiosperm contains 24 chromosomes, the number of chromosomes in each cell of the root will be

Options

A. 8
B. 4
C. 16
D. 24

Explanation

To solve the problem, we need to determine the number of chromosomes in the root cells of an angiosperm, given that an endosperm cell contains 24 chromosomes.

### Step-by-Step Solution:

1. **Identify the ploidy level of the endosperm**:
- The endosperm in angiosperms is triploid (3N). This means it has three sets of chromosomes.

2. **Determine the number of chromosomes in the endosperm**:
- We are given that the endosperm cell contains 24 chromosomes. Since it is triploid (3N), we can set up the equation:
\[ 3N = 24 \]

3. **Calculate the haploid number (N)**:
- To find the haploid number (N), we divide the total number of chromosomes in the endosperm by 3:
\[ N = \frac{24}{3} = 8 \]
- This means the haploid number of chromosomes is 8.

4. **Determine the ploidy level of root cells**:
- Root cells in angiosperms are typically diploid (2N). This means they have two sets of chromosomes.

5. **Calculate the number of chromosomes in root cells**:
- Since the haploid number (N) is 8, the diploid number (2N) can be calculated as follows:
\[ 2N = 2 \times 8 = 16 \]

6. **Conclusion**:
- Therefore, the number of chromosomes in each cell of the root is 16.

### Final Answer:
The number of chromosomes in each cell of the root is **16**.
