Three factors can limit the speed of photosynthesis-light intensity, carbon dioxide concentration and temperature. Light intensity. Without enough light, a plant cannot photosynthesise very quickly, even if there is plenty of water and carbon dioxide.
GCSE Biology Coursework Photosynthesis and limiting factors Plan for the experiment, which will evaluate how the rate of photosynthesis in a water plant is affected when the intensity of a light source is varied. Aim: To investigate how light intensity affects the rate of photosynthesis.
