Question

What is cutin? What is its function in desert plant

Answer 1

Cutin is a waxy water-repellent substance in the cuticle of plants, consisting of highly polymerized esters of fatty acids.
They help desert plants retain moisture over long periods of time.

Answer 2

1.Cutin is one of two waxy polymers that are the main components of the plant cuticle, which covers all aerial surfaces of plants. The other major cuticle polymer is cutan, which is much more readily preserved in the fossil record
2.The plant cuticle, a cutin matrix embedded with and covered by wax, seals the aerial organ's surface to protect the plant against uncontrolled water loss. The cutinmatrix is essential for the cuticle tofunction as a barrier to water loss.
