A student studied the adaptations of a holly leaf (Ilex aquifolium), which remains evergreen and active throughout the cold and dry winter months.

A diagram showing the cross-section of a holly leaf. The outermost top layer is labeled as a thick, continuous waxy cuticle. Below this is the upper epidermis, followed by a dense layer of palisade mesophyll cells, then spongy mesophyll, and finally the lower epidermis with fewer stomata than average deciduous leaves.

Explain why the thick waxy cuticle is important for the survival of the holly plant.
