The number of chromosomes in the meiocytes of Rice, Maize, Potato respectively

Options

A. 24,48,20
B. 20,24,48
C. 24,20,48
D. 24,20,34

Answer

### Step-by-Step Solution:

1. **Understanding Meocytes**:
- Meocytes are specialized cells where meiosis occurs. They are diploid (2N) cells that undergo meiosis to produce haploid (N) gametes.

2. **Chromosome Count in Angiosperms**:
- Rice, maize, and potato are all angiosperms, which means they have a sporophytic body composed of diploid cells (2N).

3. **Identifying the Chromosome Numbers**:
- Each plant has a specific number of chromosomes in its meocytes:
- **Rice**: The number of chromosomes in rice meocytes is 24 (2N = 24).
- **Maize**: The number of chromosomes in maize meocytes is 20 (2N = 20).
- **Potato**: The number of chromosomes in potato meocytes is 48 (2N = 48).

4. **Conclusion**:
- Therefore, the number of chromosomes in the meiocytes of rice, maize, and potato respectively is:
- Rice: 24
- Maize: 20
- Potato: 48

5. **Final Answer**:
- The correct option is 3: 24, 20, 48.
