Final answer:
The chloroplast is the organelle responsible for the difference between plant and animal cells in their ability to make food using energy from the sun.
Step-by-step explanation:
The organelle responsible for the difference between plant and animal cells in their ability to use energy from the sun to make food is the chloroplast. Chloroplasts are found only in plant cells and are the site of photosynthesis, a process where sunlight is converted into energy-rich molecules like glucose. Animal cells lack chloroplasts, which is why they cannot produce their own food.
