Question

As you have seen, in bright light, the rate of photosynthesis is greater than the rate of cellular respiration. How does a plant use the sugar molecules produced by photosynthesis that are not used for cellular respiration?

Answer 1

During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch. Cellulose is used in building cell walls.
