Explanation:
In photosynthesis, plants use sunlight to convert carbon dioxide and water into glucose (a form of potential energy) and release oxygen as a byproduct. The process involves capturing the energy from sunlight and converting it into chemical energy stored in the bonds of glucose. This stored energy can be later used by the plant for various metabolic processes.
