What is the use of waxy layer
Answers
A waxy layer known as the cuticle covers the leaves of all plant species. The cuticle reduces the rate of water loss from the leaf surface.
The waxy covering on plant leaves, young stems, and fruit is called the "cuticle". It is composed of cutin , a wax-like material produced by the plant that is chemically a hydroxy fatty acid. The purpose of this covering is to help the plant retain water. In arid regions, that is very important. In wetter regions, the waxy coating may help prevent infection by disease organisms. The waxy material may exist in the form of flat plates, or a mass of threads. It may be loosely formed, allowing easy passage of gases and water vapor, or it may be tightly formed, interfering with gas exchange.
In some plants, the waxy coating causes a bluish coloration. This bluish coating of wax can be rubbed off, leaving a greener appearance. It is this waxy coating that causes a blue spruce to appear blue.
