What is the first structure to prevent water loss in the leaf called? a. cuticle b. stomata c. epidermis d. mesophyll

The correct answer is option A, Cuticle

Explanation:

A plant leaf is covered by hydrophobic waxy layer  known as cuticle that prevents the loss of water through the leaves.  It acts as a barrier to the process of transpiration. It is made of cutin and lipids that are soluble in solvent and thus they are hydrophobic.  Also cutin and lipid together form  waxy covering over the epidermal layer of plant leaves which prevent any form of water exchange.
