Describe the modifications of roots for support.

(N/A) Modifications of roots for support include Prop roots and Stilt roots.
$(a)$ Prop roots: In Banyan trees (Ficus benghalensis),roots arise from the branches and grow downwards into the soil,providing mechanical support to the tree. These are called prop roots.
$(b)$ Stilt roots: In plants like Maize and Sugarcane,adventitious roots arise from the lower nodes of the stem,grow obliquely downwards,and enter the soil to provide mechanical support. These are called stilt roots.
Note: Pneumatophores (Respiratory roots) are modifications for respiration,not support. These are found in plants growing in swampy areas (e.g.,Rhizophora),where roots grow vertically upwards out of the soil to obtain oxygen.
