Question

Plants generate their food by which process?

• A. Photosynthesis
• B. Photorespiration
• C. Respiration
• D. None of these

Hint:

Equation: \(6CO_2 + 6H_2O \xrightarrow\textlight C_6H_12O_6 + 6O_2\).

Answer 1

The Correct Option is A

Step 1: Core idea. Photosynthesis converts light energy into chemical energy (glucose) using \(\mathrm{CO_2}\) and water, releasing \(\mathrm{O_2}\).
Step 2: Distinguish similar terms. Photorespiration (B) is a wasteful oxygenation reaction that reduces photosynthetic efficiency. Respiration (C) {consumes} glucose to yield ATP; it does not synthesize food.
Step 3: Conclude. \[ \boxed{\text{Photosynthesis (Option A).}} \]
