What organelles do animal cells use to convert food into energy?
flagellum
endoplasmic reticulum
nucleus
mitochondria
When an animal needs energy, it eats food. That's why animals use mitochondria to convert food into energy. Plants, on the other hand, don't seem to eat anything. Instead, they receive energy from water and sunlight. They use chloroplasts to convert light into energy through photosynthesis. The focus of this concept is to delineate the distinct differences between plant and animal cells.
