Three factors can limit the speed of photosynthesis - light intensity, carbon dioxide concentration and temperature. Without enough light, a plant cannot photosynthesise very quickly, even if there is plenty of water and carbon dioxide. Increasing the light intensity will boost the speed of photosynthesis.
Any change in the level of a limiting factor will affect the rate of. reaction. For example, the amount of light will affect the rate of photosynthesis. If there is no light, there will. be no photosynthesis. As light intensity increases, the rate of photosynthesis will increase as long. as other factors are in adequate supply. As the rate increases, eventually another factor will come. into short supply.
