________________________________________________________________________________

Leaf Anatomy (NEXT PAGE)Background Information:

The leaf is the primary photosynthetic organ of the plant. It consists of a flattened portion, called the blade that is attached to the plant by a structure called the petiole.

The outer surface of the leaf has a thin waxy covering called the CUTICLE (A). This layer's primary function is to prevent water loss within the leaf. Plants that live entirely within water do not have a cuticle. Directly underneath the cuticle is a layer of cells called the EPIDERMIS (B). A leaf has two types of epidermis: upper and lower. It protects the internal tissues of the leaf.

The vascular tissue, xylem and phloem are found within the veins of the leaf. Veins are actually extensions that run from to tips of the roots all the way up to the edges of the leaves. In the picture, XYLEM (C) is the upper layer of cells inside the vein and the lower layer of cells is PHLOEM (D). Recall that xylem transports water and phloem transports sugar.

Within the leaf, there is a layer of cells called the MESOPHYLL (E). The word mesophyll is Greek and means "middle" (meso) "leaf" (phyllon). There are air spaces between these cells to allow for gas exchange. The cells here are packed with chloroplasts, and this is where photosynthesis actually occurs.

The leaf has holes within the epidermis called STOMATA (F). Specialized cells, called GUARD CELLS (G) surround the stomata and are shaped like two cupped hands. Changes within water pressure cause the stomates to open or close. If the guard cells are full of water, they swell up and bend away from each other which opens the stoma. During dry times, the guard cells close.
