2. 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

7. 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

8. 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
