Photosynthesis is a process in which plant use heat energy to convert to a usable chemical energy (carbon dioxide and sugar ) that is needed by their growth and most essential they provide oxygen that is basic source of organisms. Although, photosynthesis occur in leaves within by cell structure chloroplast and it's has a ground substance called the stroma, and a pigment chlorophyll absorbs the light and converted to ATP that is usable energy for the cell

photosynthesis is the process of food production of plants that occurs in their leaves.

this convert light energy into chemical energy in the form of carbohydrate(starch), in the process of starch production oxygen is released.
