Answer:
Atoms are made up protons and neutrons. An atom is also very small, it is also a unit of matter.
Explanation:
"An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small, typically around 100 picometers across. They are so small that accurately predicting their behavior using classical physics—as if they were billiard balls, for example—is not possible due to quantum effects."

Waxy cuticle is a white powdery substance that is insoluble, it is found usually on the surface of stem or leave and it prevent excessive loss of water through transpiration. 
It is an adaptive mechanism used in dry areas or desert to help plants retain water that is needed for their growth by reducing amount of water loss through transpiration. 
Cactus is an example of plant with cuticle that thrive well in dry areas
