Photosynthesis and cellular respiration both involve the use and release of gases which statement correctly identifies the role of gasses in the two processes? A. Photosynthesis and cellular respiration both use oxygen and release carbon dioxide b. Cellular respiration uses oxygen and releases carbon dioxide while photosynthesis uses carbon dioxide and releases oxygen. C. Cellular respiration uses carbon dioxide and releases oxygen while photosynthesis uses oxygen and releases carbon dioxide. D. Photosynthesis and cellular respiration both use carbon dioxide and release oxygen

The correct statement that identifies the role of gases in photosynthesis and cellular respiration is:

**B. Cellular respiration uses oxygen and releases carbon dioxide while photosynthesis uses carbon dioxide and releases oxygen.**

In more detail:
- In photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) and, using sunlight, convert them into glucose (C6H12O6) and oxygen (O2).
- In cellular respiration, organisms (including plants and animals) use oxygen (O2) to break down glucose (C6H12O6) to produce energy, releasing carbon dioxide (CO2) and water (H2O) as byproducts.
