Question

Which molecule made during photosynthesis is the best source for carbon and hydrogen atoms used for cellular activities?
O carbon dioxide
O oxygen
O sugar
water

Answer 1

Answer:

carbon dioxide

Explanation:

During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. 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.
