Chlorophyll absorbs light blue with short wavelength. Chlorophyll absorbs long wavelength red light, but reflects green light, which represents the color of grass and most plants.
But chlorophyll is not only responsible for the color of the green grass and other plants, since it is important in photosynthesis, in which plants convert inorganic matter, light into usable organic matter, chlorophyll molecules absorb a quantity of light and then convert energy into their own molecules, When stimulated by the release of an electron causing chemical changes in the plant.
