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.
In a process like photosynthesis which is affected by more than one factor, its rate is limited by the factor which is closest to its minimum value. So at any point in time if one of the three factors is in low supply, this factor will be the limiting factor.
