Exosmosis

A flowering plant is planted in an earthen pot and irrigated. Urea is added to make the plant grow faster, but after some time the plant dies. This may be due to exosmosis. Urea is added because it is a fertilizer aiding plant growth but excess of urea causes increase in concentration of solutes in the soil due to which water comes out from the plant's cytoplasm eventually leading to exosmosis and thus the plant gets plasmolyzed and dies.
