Epiphytic roots are a type of aerial root that enable a plant to grow on another plant in a non-parasitic manner. Mechanical modification of root surface involves scaling and root planing. Roots anchor the plant and also absorb water and mineral nutrients. Tap root system – seen in dicotsseen in dicots 2. In monocotyledonous plants, the primary root is short lived and is replaced by a large number of roots. Manoge., 16: 281-290.
