A leaf cell of a flowering plant has 22 chromosomes. Then the number of chromosomes would be

Options

A. 11 in gametes
B. 22 in gametes
C. 44 in embryo
D. 11 in a cell of stem

Answer

To solve the question, we need to determine the number of chromosomes in different cells based on the information given about a leaf cell of a flowering plant.

### Step-by-Step Solution:

1. **Identify the chromosome number in the leaf cell**:
- The question states that a leaf cell of a flowering plant has 22 chromosomes. This indicates that the leaf cell is diploid (2n), where 'n' represents the number of chromosomes in a gamete.

2. **Determine the haploid number (n)**:
- Since the leaf cell is diploid (2n = 22), we can find the haploid number (n) by dividing the diploid number by 2:
\[ n = \frac{2n}{2} = \frac{22}{2} = 11 \]
- Therefore, the haploid number of chromosomes in gametes is 11.

3. **Analyze the options given**:
- The options provided are:
- 11 in gametes
- 22 in gametes
- 44 in embryo
- 11 in a cell of stem
- From our calculation, we know that the correct number of chromosomes in gametes (which are haploid) is 11.

4. **Evaluate the incorrect options**:
- **22 in gametes**: This is incorrect because gametes are haploid and contain only 11 chromosomes.
- **44 in embryo**: This is incorrect because the embryo is diploid (2n) and would have 22 chromosomes, not 44.
- **11 in a cell of stem**: This is incorrect because stem cells are also diploid and would have 22 chromosomes, not 11.

5. **Conclusion**:
- The correct answer is **11 in gametes**.
