Desert plants often have a thick waxy coating of cutin on the outer surface of their epidermis. This cuticle acts as a waterproof barrier, reducing water loss through transpiration and helping the plant conserve water in arid environments.

Desert plants adapt to minimize water loss through their epidermis by developing a thick waxy coating of cutin on their outer surface. This cuticle acts as a waterproof barrier, reducing transpiration and helping to conserve water in arid environments. Additionally, desert plants may have specialized structures like sunken stomata or fewer stomata overall to further reduce water loss through the epidermis.
