Plan My task is to investigate how light intensity affects the rate of photosynthesis in pondweed and will do this by measuring the amount of oxygen produced by the pondweed while in a boiling tube full of water. I will investigate how the light intensity affects the rate of photosynthesis by measuring the amount of oxygen produced. I will achieve this by counting the number of oxygen bubbles produced. Photosynthesis is the process by which the energy of sunlight is used by organisms, especially green plants, to synthesize carbohydrates from carbon dioxide and water. This process can be determined by the equation: Carbon dioxide + Water chlorophyll Glucose + Oxygen ----------------> 6CO2 + 6H2O light energy C6H12O6 + 6O2 As you can see oxygen is an end product of the process of photosynthesis so it is valid to measure the amount of this given...
