Detailed explanation-1: -Photosynthesis is a process by which green plants and certain other organisms synthesise their own food i.e. transform sunlight energy into chemical energy with the help of chlorophyll, carbon dioxide and water.

Detailed explanation-2: -Chlorophyll’s job in a plant is to absorb light-usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose, a type of sugar.

Detailed explanation-3: -Plants take light energy from the sun to carry out the process of photosynthesis. In photosynthesis, plants prepare their own food in the form of carbohydrates. Hence, plants convert light energy into chemical energy.

Detailed explanation-4: -The proton pump plays an important role in cell respiration and photosynthesis. The electron transport chain in cell respiration generates an electrochemical potential which is coupled to the proton pumps located in the membrane.
