if root of a flowering plant has 24 chromosome ,then its gamete has many chromosomes ?

Options

A. 4
B. 8
C. 12
D. 24

Answer

To solve the question of how many chromosomes are present in the gametes of a flowering plant whose root has 24 chromosomes, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Chromosome Number in Root Cells**:
- The question states that the root of the flowering plant has 24 chromosomes. These root cells are somatic cells, which means they are diploid (2n).

2. **Understand Diploid and Haploid**:
- In diploid organisms, the chromosome number is represented as 2n, where 'n' is the number of chromosomes in a haploid cell (gametes). Therefore, if the root cells are diploid and have 24 chromosomes, we can express this as:
\[ 2n = 24 \]

3. **Calculate the Haploid Number**:
- To find the haploid number (n), we need to divide the diploid number by 2:
\[ n = \frac{2n}{2} = \frac{24}{2} = 12 \]

4. **Conclusion**:
- The gametes, which are produced through meiosis, are haploid and will have 12 chromosomes.

### Final Answer:
The gametes of the flowering plant will have **12 chromosomes**.
