What is the waxy layer that covers the outer epidermal wall and prevents water loss?

Explanation:
The protective waxy coating on the surface of plant organs is the cuticle. It sits on the outer wall of epidermal cells and acts as a waterproof barrier that reduces water loss (transpiration) from the plant, helping to conserve moisture while still allowing light to reach photosynthetic tissues. The cuticle is not the epidermis itself (that’s the layer of cells beneath it), nor the deeper skin layer in animals (dermis), and it isn’t a hair. So the waxy layer described is the cuticle.
