Mario sets up an experiment to determine the source of the oxygen gas produced by photosynthesis. to determine this, he uses an isotope of oxygen called o-18. he labels the o-18 oxygen so he can follow its path through photosynthesis. plant a is given carbon dioxide that contains the o-18 isotope. plant b is given water that contains the o-18 isotope. when he examines the oxygen from both plants, only plant b produced o-18 oxygen. what conclusion should he draw about the source of oxygen produced through photosynthesis?
