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.

Factors Affecting Photosynthesis Pre-Lab: How do the following variables affect photosynthesis rate? ï· Light Intensity: The more intense the light, the quicker the plant will be able to produce oxygen gas, ATP, and NADPH. If light is not intense enough, photosystem II may be limited in how many reactions take place due to lack of energy. However if intensity is too high, the plant may be heated resulting in too high of a temperature. Therefore an optimal light intensity should exist.
