The correct Answer is:
### 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.
