The pigment responsible for most light-harvesting by plants is chlorophyll, a green pigment. The green color indicates that it is absorbing all the non-green light-- the blues (~425-450 nm), the reds and yellows (600-700 nm).
yes it can photosynthesis this is because although the leaves are red the plant still has chlorophyll however the chlorophyll is hidden so the plant does not appear green.Also â¦ the order of color is determined by the wavelenght of light.the longer the wavelength of visible light the more the red color.es it can photosynthesis this is because although the leaves are red the plant still has chlorophyll however the chlorophyll is hidden so the plant does not appear green.Also â¦ the order of color is determined by the wavelenght of light.the longer the wavelength of visible light the more the red color.
