Answer 2

Photosynthesis converts light energy into chemical energy in the form of glucose. This glucose is utilised by the plants in respiration to produce energy to carry out all the life . Plants use photosynthesis to produce carbohydrates from inorganic substrates. All organisms need energy to grow and reproduce.

Or

Unlike animals, most plants do not need to find food, because they can make it for themselves. Plants use energy from sunlight to turn water and carbon dioxide into an energy-rich sugar called glucose. This process is called photosynthesis, which means “making things with light”.
