Abstract
Phytoremediation is the use of plants to erase, destroy, or sequester pol-
lutant from the surroundings moreover to return them safe. 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.
