Explanation: Photosynthesis is the process by which green plants are able to convert light energy into chemical energy. Green plants produce their own food via photosynthesis.

6CO2 + 6H20 + (light energy) → C6H12O6 + 6O2

In words, Carbon dioxide + water + energy from sun light produces glucose and oxygen.

Carbon dioxide, water and sunlight which are the reactants are external and it is taken up by the plant. However, the products glucose and oxygen are formed from within the plant.

When photosynthesis occur in green plants, light energy is trapped and utilized to convert water, carbon dioxide and other minerals to oxygen and energy-rich organic compounds such as ATP.
