James is working on his science fair project on photosynthesis. He has decided to test the effect of two gases on the ability of plants to conduct photosynthesis. He used an aquatic plant, called Elodea, and placed two plants in two jars: one with water where the carbon dioxide had been removed and one with water without any oxygen in it. Using your understanding of the reactants and products in the photosynthesis reaction, predict what James will find in each of his two experimental jars:
