Photosynthesis Reactants and Products Steps:

• Recall the photosynthesis equation: 6CO₂ + 6H₂O + sunlight → C₆H₁₂O₆ + 6O₂.
• Identify reactants (CO₂, H₂O, sunlight) and products (glucose, O₂).
• Check each option against the equation to see if it accurately describes a role.
• Confirm the matching statement as correct.

Why C is correct:

• Sunlight supplies the energy to drive the reaction, functioning as a key reactant in the equation.

Why the others are wrong:

• A: Chlorophyll absorbs sunlight but is not produced or consumed; it's a catalyst-like pigment.
• B: Oxygen is released as a product during the light-dependent reactions.
• D: Water is consumed as a reactant to provide electrons and protons.

Final answer: C
