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.
Blackman measured photosynthesis rates under differing light intensities, CO 2 concentrations, and temperatures. As this graph shows, light is the limiting factor at low light intensities, while temperature and CO 2 concentration are the limiting factors at higher light intensities.
