14 Elodea is a plant that grows in fresh water and is often found in aquariums, Three elodea plants were placed inside inverted test tubes filled with water. One test tube
was exposed to low light, another to medium light while another was exposed to
high light. The table provided shows the results of this experiment. Notice that more
oxygen was produced by the elodea in high light.
Based on the information provided, what is the difference in volume (in ml) of
oxygen produced between the low light and high light plants at 45 minutes?
