How are cellular respiration and photosynthesis different?

Answer:
Photosynthesis and cellular respiration are opposites. Photosynthesis takes in CO2 and releases oxygen. Cellular respiration takes in oxygen and releases CO2. The CO2 that cellular respiration produces will be used for photosynthesis; the oxygen the photosynthesis produces will be used for cellular respiration.
