Photocatalytic degradation of some dyes was investigated in the presence of ZnO as semiconductor. The effect of various parameters like pH, concentration of ZnO and concentration of dyes were standardized in terms of minimum time required for bleaching of coloured solutions. The growth of plant like Allium Cepa was studied under such photocatalytic conditions. The influence of this photocatalytic treated water on the biochemical parameters like-Sugar, protein and chlorophyll contents were also observed
