use your knowledge of lipids to explain why desert plants need the waxy coating on their leaves to survive.

Answer:

The waxy coating, which is a lipid - based substance, helps desert plants survive by reducing water loss. Lipids are hydrophobic, meaning they repel water. In a desert environment where water is scarce, this waxy lipid - rich coating on the leaves forms a barrier that prevents excessive transpiration (water loss through the stomata of the leaves). It also protects the plant from extreme temperatures and physical damage.

Brief Explanations:

Lipids are hydrophobic. Waxy coating is lipid - rich. It reduces water loss in desert plants.
