a. By which process do green plants synthesize their food? b. Name the factors which take part in this process. c. Write the chemical equation of the above process.

(a) Photosynthesis is the process by which the green plants can prepare their food in the form of carbohydrate. The light energy is captured by chlorophyll, the carbon dioxide is fixed and the food is prepared. (b) There are various factors which are responsible for photosynthesis. The common factors are carbon dioxide, chlorophyll, water, light and temperature. (c) The reaction of photosynthesis is given Carbon dioxide + water + light energy → carbohydrate + oxygen. The chemical equation is given as 6CO2 + 6H2O ------> C6H12O6 + 6O2
