A typical gymnospermous plant has 8 chromosomes in leaf cells. What will be number of chromosomes in the cells of its gametophyte

Options

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

Answer

To solve the problem of determining the number of chromosomes in the gametophyte of a typical gymnospermous plant that has 8 chromosomes in its leaf cells, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Chromosome Number in Leaf Cells**:
- We know that the leaf cells of the gymnospermous plant have 8 chromosomes. This is given as the diploid (2N) number of chromosomes.

2. **Determine the Diploid and Haploid Relationship**:
- In plants, the diploid (2N) state represents the sporophyte generation, while the haploid (N) state represents the gametophyte generation.
- Since the leaf cells are diploid (2N), we can denote this as 2N = 8.

3. **Calculate the Haploid Number**:
- To find the haploid number (N), we divide the diploid number by 2:
\[ N = \frac{2N}{2} = \frac{8}{2} = 4 \]

4. **Conclusion**:
- Therefore, the number of chromosomes in the cells of the gametophyte is 4.

### Final Answer:
The number of chromosomes in the cells of the gametophyte is **4**.
