Question

A student writes the photosynthesis equation: 6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂. What does this equation tell us about energy conversion in plant cells during photosynthesis?
Question 5 options:

Plants convert light energy into chemical energy stored in glucose molecule bonds

Plants only use carbon dioxide and water, not requiring any light energy input

Plants create energy from nothing during photosynthesis reactions in chloroplasts

Plants destroy light energy and replace it with completely different glucose energy

Answer 1

Plants convert light energy into chemical energy stored in glucose molecule bonds.

Explanation: the equation shows light is required to drive the synthesis of glucose from CO₂ and H₂O. Photons provide energy to form higher‑energy chemical bonds in C₆H₁₂O₆; O₂ is a byproduct. Energy is converted, not created from nothing or destroyed.
