Q. Which of the following plants bear hygroscopic (epiphytic) roots?
Solution:
Roots that grow from any part of the plant other than radicle form adventitious roots, this is also known as false root. Modification of adventitious roots occurs for other specific functions, like, mechanical support by prop root in the banyan tree, storage of food in sweet potato, hygroscopic root in epiphytes.
The hygroscopic root is a type of modified adventitious root. Hygroscopic root absorbs moisture from an environment with the help of specialized tissue known as velamen tissue, this tissue provides support, prevent water loss and assist in water absorption.
Hygroscopic roots are found in epiphytes. Epiphytes plant lives on branches of large trees. Vanda plant possesses a hygroscopic root system.
