Leaf anatomy: Let's study a typical leaf. The leaf is protected by the upper epidermis and lower epidermis, which secrete a waxy coating called the cuticle. The epidermis is interrupted by tiny pores called stomata (singular stoma), which are flanked by guard cells. The ground tissue system of a leaf, called mesophyll, is sandwiched between the upper and lower epidermis. There are two types of mesophyll, palisade mesophyll and spongy mesophyll. The leaf’s vascular tissue system is made up of a branching network of veins. Each vein is composed of xylem and phloem tissues.
