Which of the following is a waste product released during photosynthesis in plants?

• A. Oxygen (\(O_2\))
• B. Water (\(H_2O\))
• C. Carbon dioxide (\(CO_2\))
• D. Glucose (\(C_6H_{12}O_6\))

Answer: (A)

Verified step by step guidance

1. Understand the process of photosynthesis: Photosynthesis is the process by which plants convert light energy into chemical energy, using carbon dioxide (\(CO_2\)) and water (\(H_2O\)) to produce glucose (\(C_6H_{12}O_6\)) and oxygen (\(O_2\)).
2. Identify the inputs and outputs of photosynthesis: The inputs are carbon dioxide (\(CO_2\)) and water (\(H_2O\)), while the outputs are glucose (\(C_6H_{12}O_6\)) and oxygen (\(O_2\)).
3. Recognize the role of oxygen (\(O_2\)): Oxygen is released as a byproduct during the light-dependent reactions of photosynthesis, specifically when water molecules are split (a process called photolysis).
4. Compare the options provided: Oxygen (\(O_2\)) is the waste product released during photosynthesis, while water (\(H_2O\)), carbon dioxide (\(CO_2\)), and glucose (\(C_6H_{12}O_6\)) are either inputs or useful products of the process.
5. Conclude that the correct answer is oxygen (\(O_2\)), as it is the waste product released during photosynthesis in plants.
