WebUnderstanding: • Temperature, light intensity and CO2 concentration are possible limiting factors on the rate of photosynthesis. The law of limiting factors states that when a chemical process depends on more than one essential condition being favourable, the rate of reaction will be limited by the factor that is nearest its minimum value. Webbecause the plant obtains light energy from photons being absorbed by pigments in photosystems, and this energy is what drives the photosynthetic process. At low light intensity, water will not undergo photolysis and therefore will not p roduce O 2 as a by product. As the light intensity increases, more electrons are energised in the reaction
