A student set up an experiment to show the effect of light color on photosynthesis in Elodea plants. She filled three test tubes with distilled water and placed a piece of Elodea in each of the tubes. She added a drop of phenol red, which is red in a neutral solution and yellow in an acidic solution. She blew in each tube to add carbon dioxide, which caused the distilled water to become more acidic. She exposed: Tube A to green light Tube B to white light Tube C no light (wrapped in aluminum foil) Which of the tubes should she expect to turn red the fastest?
