D. 24

Answer

To solve the question regarding the number of chromosomes in each of the four cells of a pollen tetrad, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Chromosome Number in Leaf Tip Cell**:
- The question states that the number of chromosomes in the leaf tip cell of the plant is 6. This number represents the diploid (2n) chromosome count of the plant.

2. **Understand the Concept of Pollen Tetrad**:
- A pollen tetrad consists of four cells that are formed from a single pollen mother cell through the process of meiosis.

3. **Determine the Chromosome Number of the Pollen Mother Cell**:
- Since the leaf tip cell is diploid with 6 chromosomes, the pollen mother cell (which is also diploid) will also have 6 chromosomes.

4. **Meiosis Process**:
- During meiosis, the diploid pollen mother cell undergoes two rounds of division, resulting in four haploid cells. This process reduces the chromosome number by half.

5. **Calculate the Chromosome Number in Each Pollen Cell**:
- Since the pollen mother cell has 6 chromosomes, after meiosis, each of the four pollen cells will have half of that number. Therefore, each pollen cell will have:
\[ \text{Number of chromosomes in each pollen cell} = \frac{6}{2} = 3 \]

6. **Conclusion**:
- The number of chromosomes in each of the four cells of the pollen tetrad is 3.

### Final Answer:
The number of chromosomes in each of the 4 cells of its pollen tetrad would be **3**.
