The wax cuticle covers the upper epidermis. The main task of the cuticle is to activate cuticular transpiration in a plant. Sometimes a very shiny cuticle may be present in a plant to minimize transpiration of the plant. It basically reflects back sunlight. These are the two main functions.
Non metallic coating is not very stable except Graphite coating other coating includes Sulphur coating and organic coating of polymers the temporary coating of wax ,grease and oils also may be used.
Paraffin wax can be added to Wilton candy or any other candy. Paraffin wax is completely edible and can be put in mostly any food for coating or a lubricant.
Wax repels water/liquid, it doesn't absorb it, so the water forms droplets.
Slows down evaporation of water from the pores of the leaves.
stomata is present on a leaf's lower surface. but in plants that float on water, stomata is present on a leaf's upper surface, and the lower surface is protected by a coating of wax.
To protect them against rainwater, since wax is a fat and therefore, unsoluble in water.
what you do is you boil a plant and the wax rises to the surface of the water
when frogs come onto the land they need oxygen from the air,this wax coating dissolves oxygen in it and the frog can breathe easily.also this prevent the water to flow across its skin membrane due to osmosis.
The leaf has a wax coating, so water will roll off or the leaf would float on the water.
Wax
Plants use waxy substances on their leaves to help reduce transpiration, the evaporation of water from plants. The wax helps to keep water in the plant as to not dehydrate the plant.

to protect from predators
they have coating of wax on the outer surface of their body
they are made of paper with a wax coating
The needle-like leaves and scale-like leaves help the coniferous trees by conserving water loss with the wax coating. The also give the tree more surface area for photosynthesis.
