Yоu wаnt tо knоw how the аmount of light аffects the rate of photosynthesis. To test this, you use sections of spinach leaves that have been vacuum filtrated. The vacuum filtration causes the spinach leaves to sink in bicarbonate solution because the air has been removed from the intercellular spaces. As the spinach leaves conduct photosynthesis, oxygen will be produced and the spinach leaves will begin to float again. You set up two petri dishes of recently filtrated spinach leaves in bicarbonate solution (all the leaf sections are sunken at the start of the experiment). You place one in the dark and one under a bright light. Which of the following is the most appropriate hypothesis for the experiment?
