Verified step by step guidance1
Understand that the question is asking about a specific part of a leaf's anatomy that serves a protective function.
Recall that the waxy covering on a leaf is primarily responsible for reducing water loss by evaporation.
Consider the options provided: Mesophyll, Stomata, Epidermis, and Cuticle.
Recognize that the Mesophyll is the inner tissue of a leaf where photosynthesis occurs, and Stomata are pores involved in gas exchange.
