Every shade of green you can imagine can be found in whole plant foods. The green color in plants is because of a pigment called chlorophyll. Chlorophyll makes foods appear green because it reflects green-colored light and absorbs other colors. Darker green vegetables tend to have more chlorophyll. Plants use chlorophyll to make food during photosynthesis. Chlorophyll’s job is to absorb sunlight so it can be stored as energy and used to convert carbon dioxide and water into glucose. Plants use glucose and other nutrients to make leaves, and edible parts of plants.
