Learning Objectives:1.1 Demonstrate an understanding of how biologists classify organisms according to how closely they are related to one another including: a) Species – groups of organisms that have many features in common, b) Genus – contains several species with similar characteristics, c) Family – comprising of several genera,d) Order – comprising of several families, e) Class – comprising of several orders, f) Phylum – comprising of several classes, g) The Five Kingdoms – animalia, plantae, fungi, protoctista and prokaryotae 1.2 Describe the main characteristics of the five kingdoms including: a) Animalia – multicellular, do not have cell walls, do not have chlorophyll, feed heterotrophically, b) Plantae – multicellular, have cell walls, have chlorophyll, feed autotrophically, c) Fungi – multicellular, have cell walls, do not have chlorophyll, feed saprophytically, d) Protoctista – unicellular, have a nucleus, e) Prokaryotae – unicellular, have no nucleus 1.3 Explain why scientists do not classify viruses in any of the five kingdoms and regard them as non-living
