Photosynthesis Quiz: Ultimate Questions!

How much do you know about photosynthesis? Photosynthesis is a procedure used by plants to convert light energy into chemical energy stored and later used for food. To perform photosynthesis, you need three things. These include sunlight, carbon dioxide, and water, and the plant takes in water from the roots, carbon dioxide through the air and light energy from the sun. This quiz will convert your knowledge into a passing score.
