Question

14 plant cells use photosynthesis to make food. plants cells also use cellular respiration to get energy from the food they make. how is cellular respiration different from photosynthesis? cell respiration a photosynthesis requires energy from food, and cellular respiration requires energy from the sun. b photosynthesis produces oxygen, and cellular respiration produces carbon dioxide. c photosynthesis requires oxygen, and cellular respiration requires carbon dioxide. d photosynthesis produces atp, and cellular respiration produces sugars.

Explanation:

• Option A: Photosynthesis uses energy from the sun, not food. Cellular respiration uses energy from food. So this option is incorrect.
• Option B: Photosynthesis equation: \(6CO_2 + 6H_2O+light\ energy

ightarrow C_6H_{12}O_6+6O_2\). It produces oxygen. Cellular respiration equation: \(C_6H_{12}O_6 + 6O_2
ightarrow6CO_2+6H_2O + energy\). It produces carbon dioxide. This option is correct.

• Option C: Photosynthesis requires carbon dioxide (\(CO_2\)) and water (\(H_2O\)), not oxygen. Cellular respiration requires oxygen (\(O_2\)). So this option is incorrect.
• Option D: Photosynthesis produces sugars (\(C_6H_{12}O_6\)). Cellular respiration produces ATP (adenosine - tri - phosphate). So this option is incorrect.

Answer:

B. Photosynthesis produces oxygen, and cellular respiration produces carbon dioxide.
