Does the Intensity of Light Affect the Rate of Photosynthesis? Introduction: To make their own food plants photosynthesise. To do this they need carbon dioxide, sunlight, and water. Carbon dioxide and water react together to form glucose and oxygen. This reaction requires energy (in the form of sunlight). The sunlight is used by the chlorophyll in the leaves to make the reaction happen. Carbon dioxide, temperature and the amount of time exposed to sunlight all affect the rate of photosynthesis, but does the light intensity? Plan: Obtain some pondweed and cut off a small section underwater. Put this in a test tube of water and put the test tube in a clamp. Position a lamp at varying distances from the tube.
