Effects of Light Intensity on the Rate of PhotosynthesisAim To work out how light intensity can affect the rate of photosynthesis. Hypothesis I think that the further away the light source is the smaller the rate of photosynthesis is. This is because there is a further distance for the light to each the plant in order for it to photosynthesise. Although the closer the light source is, the more photosynthesis, the light source could also kill or damage the Elodea (type of pondweed) because it could become too hot and denature its cells.
