Question

what is the main purpose of photosynthesis in plants? to produce energy - rich glucose, to break down glucose, to absorb oxygen, to release carbon dioxide

Explanation:

Photosynthesis in plants uses light - energy to convert carbon dioxide and water into glucose and oxygen. The main purpose is to produce glucose which is used for energy and growth. Breaking down glucose occurs in respiration. Absorbing oxygen and releasing carbon dioxide are also processes of respiration, not photosynthesis.

Answer:

To produce energy - rich glucose
