      Grass is green because it contains something called chlorophyll. Chlorophyll is green, and it’s found inside the leaves of plants. It helps to convert light from the sun into food for the plants (this is called photosynthesis).

      Much like flamingos and carrots, grass contains a special pigment that gives it a green colour.

      This pigment is called chlorophyll.

      Chlorophyll is used during photosynthesis. This is a process that takes places when a plant uses sunlight to turn carbon dioxide and water into sugar 🙂 .

      As Jen and Imogen have correctly said grass is green due to chlorophyll. But the reason we see green for grass is the surface of an object reflects some colors and absorbs all the others. We perceive only the reflected colors. So this chlorophyll has a green pigment so it absorbs all the other colours and reflects the wavelengths that make up the green colour.
