Question

What is cutin? What is its function in desert plant?

Answer 1

Cutin:

1. Cutin is one of two waxy polymers that make up the plant cuticle, which covers all of the plant's aerial surfaces.
2. Cutin is a waxy-water insecticidal substance found in plant cuticles that is composed of highly polymerized esters of fatty acids.

The function of cutin in desert plant:

1. Cutin's primary role is to protect the underlying layers. Desert plants have an abundance of cutin on their leaves to avoid water loss through transpiration.
2. Cutin is the synthetic polymer network that endorses the rest of the cuticle components and plays a major role in the water resistance of higher plant leaves and fruits.
