- Diagram 3: Light Wave Absorption of Chlorophyll a and b. Chlorophyll a Chlorophyll b 400 450 500 550 600 650 700 Wavelength (nm) Plant chlorophyll chemicals will absorb, or take in, light wave energy in order to produce their own organic molecules used for cellular energy. Reflected light refers to those wavelengths of light that will "bounce off" of the chlorophyll and not be absorbed. Select the conclusion that most accurately summarizes the data in diagram 3. Red and blue light waves have equal importance during photosynthesis. The majority of light energy is attained from red light, while the blue light waves provide additional light energy to photosynthesis. The majority of light energy is attained from blue light, while the red light waves provide additional light energy to photosynthesis. Medium length light waves are important to photosynthesis Absorptionarrow_forwardWhich of the following correctly describes the flow of electrons during photosynthesis?

It would increase the rate of photosynthesis because of the increased production of food. B. It would limit the amount water plants are able to take in, resulting in a slower rate of photosynthesis. C. It would increase the production of oxygen because the plant would need to work hard to feed themselves. С. D.
