Pollen grains of a plant whose 2n = 8 are cultured to get callus by tissue culture method. What would be the number of chromosomes in the cells of the callus ?

Explanation

To solve the question regarding the number of chromosomes in the cells of the callus derived from pollen grains of a plant with a diploid number (2n) of 8, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Diploid Number**: The question states that the plant has a diploid number (2n) of 8. This means that the total number of chromosomes in the diploid cells is 8.

2. **Determine the Haploid Number**: Pollen grains are produced through meiosis, which results in haploid cells. To find the haploid number (n), we divide the diploid number by 2:
