Biosorption is an effective process for the removal and recovery of heavy metal ions from aqueous soAlutions. In the present investigation, naturally available plant based biosorbents viz., powdered biomass of Sargassum wighti was examined to find out their efficiency on the biosorption of heavy metals from aqueous solution. Retrival efficacy of different concentrations of seaweed biomass on Oryza sativa seedlings was examined. Application of sea weed powder accelerated the growth of the plants. Addition of seaweed caused more accumulation of chlorophyll a, b, carotenoid and class of accessory pigments than the cadmium alone treated seedlings. The impact of seaweed on the biochemical constituents in terms of soluble sugar, free amino acid, soluble proteins and leaf nitrate was studied. Further, the scavenging enzymatic activities were decreased with the increased concentration of seaweed biomass reveals the stress relieving nature of plants.
