Chlorophyll is a green pigment in plants responsible for harnessing sunlight to help the plant produce sugars through the proces
s of photosynthesis. If several tomato plants were to be grown under lamps producing only a single color of light, what would be the least effective choice for light color
The least effective choice of color would be green color. The plants absorb all different wavelength lights of the visible light spectra but the only color that is not absorbed and reflected back is green color light.
The reflection of the green color light gives the plant its green color. The most absorbed color is violet and orange (chlorophyll a) and blue and yellow by chlorophyll b. Therefore, for the production of sugar and fruit in this tomato plant, green color light would be least effective.
