Content: The need for higher light intensities for maximum photosynthesis of an entire tree is due to partial illumination of the inner leaves. ADVERTISEMENTS: Both quality and intensity of light influence photosynthesis. Light between wavelength of 400 nm and 700 nm is most effective, for photosynthesis. This light is called photosynthetically active radiation (PAR). Photo-Oxidation: When the light intensity is increased beyond a certain point, the cells of the leaf or other photosynthesizing organ become vulnerable to chlorophyll-catalysed photooxidations. With the result, many more chlorophyll molecules become excited than can be utilized causing the bleaching of chlorophyll and inactivation of important enzymes. The presence or absence of carotenoids and the concentration of carbon dioxide also influence the amount of photo-oxidation. The carotenoids have a protective role in photo-oxidation.
