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.
There are three main factors affecting photosynthesis: Light intensity; Carbon dioxide concentration; Temperature; Light intensity. If there is little light shining on a plant, the light-dependent reactions will not work efficiently. This means that photolysis will not happen quickly, and therefore little NADPH and ATP will be made.
