Designation (Greek morphé = shape, form) for the teaching of the forms. It forms a sub-area in many branches of science. In biology, morphology is the study of the shape and structure of organisms (humans, animals, plants). It includes the classification of organisms based on their shape and the phenological Change in the course of growth cycle, Thus, she is the basis for the taxonomy and for evolution. The term morphology was first used in 1796 by Johann W. von Goethe (1749-1832) and, independently of this, coined in 1800 by the physiologist Karl Friedrich Burdach (1776-1847). In comparative morphology, an attempt is made to recognize in the variety of forms of individuals certain characteristics of an organism and to derive a classification on the basis of characteristic features of the basic organs. The three basic organs of plants are sheet, Shoot axis (connects the other two parts) and root.
