What gas is given off by a plant as a byproduct during photosynthesis?
|
|
carbon dioxide
|
|
|
nitrogen
|
|
|
hydrogen
|
|
|
oxygen
|
Explanation:
Detailed explanation-1: -Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.
Detailed explanation-2: -Oxygen is released as a byproduct. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process. Carbon dioxide and water are products of this reaction.
Detailed explanation-3: -During photosynthesis, plants take in carbon dioxide and give out oxygen as a byproduct.
