Biology Practice Test on Photosynthesis

Photosynthesis is the process responsible for ‘life’ on this planet. Photosynthesis literally means synthesis with the help of light.The green plants carrying out photosynthesis are called autotrophic plant, i.e. they can synthesize their own food. During the process of photosynthesis light energy (solar energy) is converted to chemical energy and stored in the organic matter like carbohydrates.
