1 Taxonomy Grade 7 science Westmount High School Ms Hipfner/ Ms Malde 1

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

3 Living organisms Divided into six Kingdoms AnimalsFungiProtistsBacteriaArchaeansPlant Eat food absorb food no nucleus Photosynthesis one- or few- celled Organisms no nucleus 3

4 Further subdivisions: Kingdom Phylum / Division Class Order Family Genus Species K ings P lay C hess O n F lying G old S ets 4

5 Animal Kingdom InvertebratesVertebrates Sponges Cnidarians Worms Echinoderms Mollusks Arthropods Fish Amphibians Reptiles Birds Mammals 5

6 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

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
