A typical leaf shows three main parts: 1) petiole, 2) leaf base, and 3) leaf blade or lamina, each performing specific functions. Xylem cells, which transport water and nutrients from the roots to the rest of the plant, are dead at functional maturity. The internal structure of the leaf is protected by the leaf epidermis , which is continuous with the stem epidermis. Terms in this set (11) cuticle. xyloem. > vacuole. These leaves are acicular in shape and are more or less rounded in cross-section. > air spaces. If you were to look carefully at the cross section of a stem, you would find several layers inside, each of which has a different job. Leaf tissues are composed of layers of plant cells. How does the structure of the spongy mesophyll contribute to its function? You can see these if you look at a transverse section (cross-section) of a leaf under a microscope. The Leaf. PLAY. A leaf (plural leaves) is the principal lateral appendage of the vascular plant stem, usually borne above ground and specialized for photosynthesis.The leaves and stem together form the shoot. Human Anatomy Body. They generally exhibit striate venation because the major veins run parallel to one another at some point in the leaf. Created: Jun 7, 2012.

Chlorophyll , the substance that gives plants their characteristic green colour, absorbs light energy . Evelyn Bailey. Leaf Structure and Function ... (Cross Section in Above Right Photo) Color is produced by the balance of pigments in the leaf tissue and also by the distribution of pigments in the plastids as well as the air spaces inside of the leaf that scatter the light penetrating into the leaf. These tissues include a mesophyll tissue layer that is sandwiched between two layers of epidermis. transports food made during photosynthesis from the leaves to the rest of the plants. Botanists call the upper side the adaxial surface (or adaxis) and the lower side the abaxial surface (or abaxis).

Leaf Cross Section Functions. A = palisade mesophyll; B = upper cuticle; C = xylem; D = phloem; E = upper epidermis; F = vein (vascular bundle); G = lower epidermis; H = lower cuticle; I = spongy mesophyll; J = guard cell; K = stoma Function: The palisade mesophyll produces carbohydrates by photosynthesis.
