The Cuticle of a Plant is Primarily for ____

Question

The cuticle of a plant is primarily for ____.  
A) absorption of carbon dioxide
B) water conduction
C) water conservation
D) protection from strong sunlight
E) mechanical support

Accepted Answer

The cuticle of a plant is a waxy layer on the outer surface of leaves, stems, and other aerial plant organs. This layer prevents the loss of water from the plant and thus, helps in water conservation. The cuticle also protects the plant from diseases and external damages. Though it provides a slight protection from strong sunlight, it is not its primary function. The cuticle does not have any role in absorption of carbon dioxide, water conduction or mechanical support.
