### Instruction: Why are many plants green?
### Response: Many plants are green because of the use of a green pigment, chlorophyll, in the process of photosynthesis. Photosynthesis is the process that a plant uses to use its stored energy and carbon dioxide and water into glucose. Chlorophyll’s role is to provide this energy by absorbing sunlight and turn that sunlight into energy. Chlorophyll is green as it absorbs all collards of white light except for green. This color is reflected back which gives chlorophyll a green appearance.
