Suppose an experiment is performed in which plant I is supplied with normal carbon dioxide but with water that contains radioactive oxygen atoms. Plant II is supplied with normal water but with carbon dioxide that contains radioactive oxygen atoms.
Each plant is allowed to perform photosynthesis and the oxygen gas and sugars produced are tested for radioactivity.
Which plant would you expect to produce radioactive sugars and which plants would you expect to produce radioactive oxygen gas?
and WHY!?

Plant I will release radioactive oxygen atoms because the radioactive H2O is split through photolysis to make radioactive O2. Plant II will make radioactive sugars because the CO2 is radioactive.
