A leaf is the main organ of photosynthesis and transpiration in plants. Leaves possess many shapes, sizes, functions and manners of being. Leaves of most woody trees and bushes consist of a flat blade connected to the woody stem or twig via a slender, stick-like petiole. The blade and the petiole make up the leaf. Hundreds, even thousands, of leaflets can occur in a single compound leaf. A poison ivy leaf consists of three leaflets. Most but not all leaves, even compound leaves, are shaped in such a way that they more or less display bilateral symmetry.
