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.
Light-Not enough light, not enough energy for the light reaction to take place Temperature-If the temp. is too high, or too low Water-If there is not enough water present, Carbon dioxide-More CO2, higher rate Oxygen-More O2, lower rate. The factors that affect the rate of photosynthesis and how.
