CLASSIFICATION OF LIVING ORGANISMS Classification: an orderly grouping of organisms according to selected criteria The study of classifying organisms is called taxonomy – Provides universal names for organisms – Provides a reference for identifying organisms 2

Animal Kingdom Vertebrates Fish Amphibians Reptiles Birds Mammals skin: smooth or scaly exclusively aquatic/Breath only in water Lay eggs skin: smooth aquatic and terrestrial / breath in and out of water Lay eggs, or produce eggs that hatch in the females body skin: scales or a shell aquatic or terrestrial / breath out of water lay eggs feathers Exclusively terrestrial most give birth to developed young nurse their young fur terrestrial or aquatic / breath only out of water 6

Plant Kingdom AlgaeMosses and Liverworts FernsConifersFlowering plants No roots, leaves, stems live in water form strings of cells No true roots peel off easily No channels conducting plant nutrients (sap) Have roots, stems and leaves Have channels for conducting plant nutrients (sap) No seedsNaked seeds in a cone Seeds in a fruit Reproduce by spores Needle or scale leaves Keep them in winter flowers 7

Two individuals belong to the same species if … They share similar characteristics, – for example physical resemblance They can reproduce (if of opposing sex), The children of these two individuals are viable (survive), the children themselves can reproduce successfully (they are fertile). 8
