Content: 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.  Colour of Light: Every wavelength of light has a different colour and a different amount of stored energy in the photon; while dependant on the plant, it is hypothesized that shorter wavelengths (visible) with more energy will increase the photosynthesis rate. Too weak of a ray or too strong of a ray will limit oxygen production.  Carbon Dioxide Levels: Carbon dioxide in excess should not disrupt the photosynthesis cycle, however after a certain point, increasing CO2 levels would no longer be effectively increasing photosynthesis rates.  Temperature:
