If the number of chromosome in root cell is 14, then what will be the chromosome number in synergids?
(a) 14
(b) 21
(c) 7
(d) 28

Options

A. 14
B. 21
C. 7
D. 28

Answer

To solve the problem, we need to determine the chromosome number in synergids based on the information provided about the root cell. Here’s a step-by-step breakdown of the solution:

### Step-by-Step Solution:

1. **Understanding Chromosome Number in Root Cells**:
- The question states that the number of chromosomes in the root cell is 14. Root cells are typically diploid (2n), which means they contain two sets of chromosomes.

2. **Identifying the Diploid Number**:
- Since the root cell is diploid and has 14 chromosomes, we can denote this as 2n = 14. Here, "n" represents the haploid number, which is the number of chromosomes in a single set.

3. **Calculating the Haploid Number**:
- To find the haploid number (n), we divide the diploid number by 2:
\[ n = \frac{2n}{2} = \frac{14}{2} = 7 \]
- Therefore, the haploid number of chromosomes is 7.

4. **Understanding Synergids**:
- Synergids are specialized cells found in the embryo sac of flowering plants and are haploid. This means they contain only one set of chromosomes.

5. **Conclusion**:
- Since synergids are haploid and we have calculated that the haploid number (n) is 7, the chromosome number in synergids will also be 7.

### Final Answer:
The chromosome number in synergids is **(c) 7**.
