In photosynthesis, solar energy is converted to chemical energy. The chemical energy is stored in the form of glucose (sugar). Carbon dioxide, water, and sunlight are used to produce glucose, oxygen, and water.
light energy from the sun is being converted to chemichal potenstial energy(which is stored energy). Photosynthesis is a chemical process that takes place in the presence of sunlight, wherein plants make their food and build stores of energy. This phenomenon occurs in chlorophyll containing plant cells.
