How Does Light Intensity Affect the Rate of Photosynthesis in Pond Weed? Prediction I predict that the higher the intensity of light, the quicker the rate of photosynthesis will be in pond weed. Chlorophyll is the chemical which absorbs light energy and passes it to the process of photosynthesis. This means that it acts as a catalyst upon plants for photosynthesis. Therefore, it can speed up the rate of reaction. So, if the light is not intense enough upon the chlorophyll, then it won't absorb enough light energy, which means that it won't activate photosynthesis. I also predict that as I move the lamp away from the pond weed, the intensity of light will reduce, thus reducing the amount of oxygen produced by the plant. So, if I move the away at 25cm distance, then the pondweed will produce (an average of) 33 bubbles of oxygen. But, if the distance is 30cm, it...
