PREDICTION

I predict that as the light intensity is increased the rate of photosynthesis will also increase. However at a certain point the light will reach a certain point where the rate will not increase any more. The chloroplasts will no longer be able to absorb any light so the rate will stay at its optimum level or even decrease. At this point light is no longer limiting. The graph of results will probably look something like this:

Light is limiting at this point Maximum rate of photosynthesis light is no longer limiting.
