Question

3. Which one of these reactions occurs during
photosynthesis?
a) carbon dioxide is reduced and water is oxidized .

b) water is reduced and carbon dioxide is oxidized .

c) bandai oxide and water are both oxidized .

d) carbon dioxide and water are both reduced .​

Answer 1

Answer:

Photosynthesis is the process in which autotrophs such as green plants use carbon dioxide and water in presence of sunlight to synthesize nutrients such carbohydrates in the form of glucose and release oxygen. In this carbon dioxide is reduced to glucose and water is oxidized to release oxygen.

a.Water is oxidized in photosynthesis, which means it loses electrons, and carbon dioxide is reduced, meaning it gains electrons.

Answer 2

Answer:

a) carbon dioxide is reduced and water is oxidized .

Explanation:

Photosynthesis is the process in which autotrophs such as green plants use carbon dioxide and water in presence of sunlight to synthesize nutrients such carbohydrates in the form of glucose and release oxygen. In this carbon dioxide is reduced to glucose and water is oxidized to release oxygen. Hence the reaction is an oxidation-reduction reaction. Thus the correct answer is option a.
