Plant adopts different kinds of mechanism to remove inorganic or organic pollutant by utilizing its biochemical, physiological and genetic attributes. Pollutant detoxification mechanism involved in plants is quite similar to that involved in animals and is based on "green liver concept". In addition, plant associated rhizospheric microflora play a pivotal role in degrading inorganic/organic pollutants. This chapter will focus on the strategies used by the plants to remove inorganic/organic pollutant from surroundings.
