Chloroplasts contain chlorophyll and carotenoids. Chlorophyll directly absorbs light for use in photosynthesis. Carotenoids absorb light and transfer the energy from light to chlorophyll. The efficiency of photosynthesis varies with the wavelengths of the light that illuminates the chloroplasts. In an experiment to study the relationship between the incoming light wavelengths and the chemical reactions of photosynthesis using a species of green algae, a researcher labeled the CO2 supply to the algae with 14C, and the H2O with 18O. Which of the following results is expected? More 14C is found in the algae when it is illuminated by green light than when it is illuminated by blue-violet and red light. More 18O is found in the algae when it is illuminated by green light than when it is illuminated by blue-violet and red light. More 14C is found in the algae when it is illuminated by blue-violet and red light than when it is illuminated by green light. More 18O is found in the algae when it is illuminated by blue-violet and red light than when it is illuminated by green light.
