Content: 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. With high concentrations of carbon dioxide, the consumption of oxygen of photo-oxidation takes place at much higher light mtensities. Light Quality: White light, that comes from the sun, is composed of different wave lengths, ranging from the relatively long wave or red light (700 nm) through successively shorter waves to violet light (440 nm). When passed through a glass prism, white light is resolved into seven colours. The band of colours is the visible spectrum.
