A '''leaf''' is the main organ of [[photosynthesis]] and [[transpiration]] in [[plant]]s. Leaves possess many shapes, sizes, functions and manners of being. Leaves of most woody [[tree]]s 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]]. | A '''leaf''' is the main organ of [[photosynthesis]] and [[transpiration]] in [[plant]]s.
