Modification of roots and leaf takes place in order to perform various functions. In marshy areas, roots of plants such as Rhizophora grow vertically upward in order to get oxygen for respiration. In plants like maize and sugarcane, they develop roots from the basal nodes of the main stem that help in supporting the plant. These are known as Stilt roots. In the Banyan (Ficus benghalensis) tree, roots which give support to growing branches are called prop roots
