The waxy waterproof layer on the leaves and some stems of plants is called the ____
A
root
B
stomata
C
petal
D
cuticle
Explanation: 

Detailed explanation-1: -Answer: 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.

Detailed explanation-2: -Plant cuticle is the outermost layer of plants, which covers leaves, fruits, flowers, and non-woody stems of higher plants. It protects plants against drought, extreme temperatures, UV radiation, chemical attack, mechanical injuries, and pathogen/pest infection.

Detailed explanation-3: -The correct answer is Cuticle. The cuticle is the waxy hydrophobic layer on the surface of the leaf epidermis that prevents the loss of moisture and reduces environmental stress.

Detailed explanation-4: -The cuticles are protective, hydrophobic, waxy coverings produced by the epidermal cells of leaves, young shoots and all other aerial plant organs. Cuticles minimize water loss and effectively reduce pathogen entry due to their waxy secretion.

Detailed explanation-5: -In some higher plants, the cuticle is a water-impervious protective layer covering the epidermal cells of leaves and other parts and limiting water loss. It consists of cutin, a waxy, water-repellent substance allied to suberin, which is found in the cell walls of corky tissue.
