Chapter 28, Problem 2TYK
Summary Introduction
Introduction:
The plant organs, such as leaves and young shoots are covered with the thin layer of a waxy substance called the cuticle. The cuticle is composed of the cutin, which is hydrophobic in nature. The cuticle does not allow the passage of the water and gases through it.
