A Quiz To Test Your Knowledge On Photosynthesis
How do plants create energy? Photosynthesis is the process used by plants and to convert light energy into chemical energy. Take this quiz to find out how much you know about plant photosynthesis. Answer the following multiple choice questions and then see your score. Better yet, stump your family and friends by asking them to take this quiz.
1. Light supplies the energy for photosynthesis. What is the overall chemical reaction?
Oxygen and water are converted into glucose sugar and carbon dioxide.
Carbon dioxide and water are converted into glucose sugar and oxygen.
Sugar is broken into water and oxygen.
Carbon dioxide and oxygen are converted into glucose sugar and water
2. Which of the following might increase the rate of photosynthesis?
Decreasing the duration of light
Decreasing the intensity of light
Increasing the amount of oxygen
Increasing the amount of carbon dioxide
