photosynthesis and cellular respiration both involve the use and release of gases. which statement correctly identifies the role of gases in the two processes.

Answer 1

In photosynthesis, the role of gases involves the intake of carbon dioxide (CO2) by plants, which is used in the process of synthesizing glucose. Additionally, oxygen (O2) is released as a byproduct during photosynthesis.

On the other hand, in cellular respiration, the role of gases involves the intake of oxygen (O2) by organisms, which is then used to break down glucose and release energy. As a byproduct of cellular respiration, carbon dioxide (CO2) is released.

To summarize, photosynthesis uses carbon dioxide (CO2) and releases oxygen (O2), while cellular respiration uses oxygen (O2) and releases carbon dioxide (CO2).
