A potted geranium sits on the windowsill of your dorm room, absorbing sunlight. You place a large box like filter over your plant for a few days. The filter prevents all light except green light from entering. If you weigh it after a few days (discounting the weight of the water) will it weigh more or less than before?   A. It will weigh more because carbon fixation is taking place. B. It will weigh more as long as it has enough of the terminal electron acceptor oxygen. C. It will weigh less because it is still undergoing respiration. D. It will weigh less because the energy gained from a green photon of light raises electrons in chlorophyll to a lower excited state than red or blue light.
