Prediction : I predict that as I increase the distance between the light source and the Canadian Pondweed (reducing the light intensity), the volume of oxygen produced within the time limit (the measure of the rate of photosynthesis) will decrease. This will happen because as the light source is moved further away, less light rays will reach the surface of the Pondweed, shown by this diagram; Light source Light rays Pondweed Light rays Light source Pondweed This will mean that less light (particles or waves) will go through the clear Cuticle and upper Epidermis and reach the palisade layer.
