The correct comparison and contrast regarding the functions of chloroplasts and mitochondria from the options provided is:
They are responsible for the conversion of energy in either plant or animal cells.
Explanation:
- Chloroplasts are found in plant cells and some algae, and they are responsible for photosynthesis, converting sunlight into chemical energy stored in glucose.
- Mitochondria are found in both plant and animal cells and are responsible for cellular respiration, converting biochemical energy from nutrients into ATP, which is used as an energy currency by the cell.
The other options do not accurately reflect the functions of these organelles.
