The correct Answer is:
To determine which cells have the highest number of mitochondria, we need to analyze the options given: 1. **Parenchyma Cells**: - These are thin-walled living cells that contain a prominent nucleus and protoplasm. - Their main functions include storage and secretion. - **Conclusion**: Parenchyma cells do not have the highest number of mitochondria. 2. **Sieve Tubes**: - Sieve tubes are elongated living cells found in the phloem. - Their primary function is to transport carbohydrates throughout the plant. - **Conclusion**: Sieve tubes are not known for having a high number of mitochondria. 3. **Meristematic Tissues**: - Meristematic tissues are regions of actively dividing cells. - These cells require a lot of energy for growth and division, which is provided by mitochondria. - **Conclusion**: Meristematic tissues are known to have the highest number of mitochondria among the options provided. 4. **Collenchyma**: - Collenchyma cells have thickened cell walls and provide support to growing parts of the plant. - They are not characterized by a high number of mitochondria. - **Conclusion**: Collenchyma cells do not have the highest number of mitochondria. **Final Answer**: The highest number of mitochondria are found in **Meristematic Tissues**. ---
