In cell biology, the primary difference between anaerobic and aerobic respiration is that aerobic respiration requires:

water |
|
mitochondria |
|
sugar |
Some plant cells produce their own energy through photosynthesis which is the process by which sunlight, carbon dioxide, and water react to make sugar and oxygen. Animal cells cannot produce their own energy and, instead, generate energy when mitochondria consume outside sugar and oxygen through aerobic respiration.
