Phytoremediation uses plant roots to clean polluted soil and water. They can remove, by endo-cytosis, and degrade both small organic molecular pollutants (ammunition wastes, chlorinated solvents, and herbicides) and large organic molecular pollutants (crude oil and polyaromatic hydrocarbons) in the environment. The degraded products can then be incorporated in the plant's tissues.
