In photosynthesis, water undergoes ______ while carbon dioxide undergoes ______.

A. oxidation .... reduction
B. reduction .... oxidation
C. no change .... oxidation
D. none of the above

a, oxidation is when a molecule loses electrons. in this case, water is losing an electron and CO_2 is gaining an electron, which then makes it an energy rich sugar molecule

In photosynthesis, water is oxidized and carbon dioxide is reduced, making the correct answer option a. oxidation .... reduction.
Understanding the Redox Process in Photosynthesis
In photosynthesis, water undergoes oxidation while carbon dioxide undergoes reduction. This is because during photosynthesis, hydrogen ions are added to carbon dioxide, thus it is being reduced. Conversely, hydrogen ions are removed from water during the process, meaning water is being oxidized. This dual process is essential for the formation of carbohydrates and oxygen.
The correct option that fills in the blanks correctly is therefore: a. oxidation .... reduction. Based on the chemical equation 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂, we can see that carbon dioxide is reduced to glucose (C₆H₁₂O₆) and water is oxidized to produce oxygen (O₂).

In photosynthesis, water undergoes oxidation while carbon dioxide undergoes reduction. Water is split to release oxygen, while carbon dioxide is converted into glucose. Thus, the correct answer is (A) oxidation .... reduction.
