Part 1: Answers to Preliminary Questions
• Photosynthesis is the process by which green plants use sunlight energy to manufacture food using water and carbon dioxide as raw materials.
• An increase in the intensity of sunlight increases the rate of photosynthesis up to a given level.
• Photosynthesis and respiration processes complement each other. It is possible to examine the relationship between photosynthesis and cellular respiration under controlled experimental conditions. This can be conducted by setting up an experiment with two sets of experimental set-ups. In each set-up, there should be two test-tubes: one with a high concentration of carbon dioxide and another with a high concentration of oxygen. One pair of test tubes, consisting of a test-tube with a high concentration of oxygen, ...
