Modifications to carry on special mechanical functions

1. Prop Roots- hanging structures that support a banyan tree

2. Stilt roots

Stilt roots of Sugarcane and Maize are supporting roots which arise from the lower nodes of the stem. These roots grow downwards and penetrate the soil and provide mechanical support to the plant.

Ex- Sugarcane  

3.Climbing roots

climbers can climb up their supports as adventitious roots growing from the nodes.
