Detailed explanation-1: -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: -To reduce water loss the leaf is coated in a waxy cuticle to stop the water vapour escaping through the epidermis. Leaves usually have fewer stomata on their top surface to reduce this water loss. Leaves enable photosynthesis to occur.
Detailed explanation-3: -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 cutin matrix is essential for the cuticle to function as a barrier to water loss.
