Compare photosynthesis and cellular respiration
The idea
Photosynthesis uses carbon dioxide, water and light energy to form sugars and oxygen in the simplified model.
Step by step
- Photosynthesis uses carbon dioxide, water and light energy to form sugars and oxygen in the simplified model.
- Aerobic cellular respiration uses sugar and oxygen, releasing carbon dioxide and water while transferring energy.
- Plants perform cellular respiration as well as photosynthesis.
Example
Which process uses light energy to make sugar from carbon dioxide and water in the simplified overall model?
Answer
photosynthesis
Photosynthesis transfers light energy into chemical energy stored in sugars.
