The Diversity of Life Classification – based on evolution and bone structure Need for Classification: • To study unity and diversity of living things • To make things easier to study • Based on evolution and bone structure Phylogenetic Tree Background Vocabulary • Heterotrophic Nutrition: – organisms must obtain their own food Autotrophic Nutrition • Organisms can make their own food – examples: chemosynthesis, photosynthesis Multicellular organisms • An organism made up of more than one cell Unicellular Organisms • An organism made up of one cell Euglena Ameba Paramecium History of Classification • Used to be 2 or 3 kingdoms • Development of microscope changed that Modern Classification System Grouped into 5 Kingdoms (6) • Plant – Multicellular – autotrophic (photosynthesis) Animal • -multicellular • - heterotrophic (obtain food) Monera • Generally unicellular • Some are heterotrophic, some are autotrophic • NO distinct nucleus/nuclear membrane • MO NO • Ex. Bacteria, blue-green algae Protista • Generally unicellular • Some are heterotrophic, some are autotrophic • Have a distinct nucleus • Ex. Ameba, paramecium, euglena Fungi • Heterotrophic • Multicellular • Digest and absorb nutrients from the environment • Ex. Mushrooms, yeast (only unicellular fungus) Classification Song • The monerans have another name it’s bacteria • The protists are unicellular like the ameba • Then we have the fungi like mushrooms, mold and yeast • And don’t forget the plants that can make their own feast • But animals they’re last not least, from bugs to birds to hairy beasts Taxonomy • Division of biology that deals with the classification and naming of living and extinct organisms Kingdom Broadest – many organisms Phylum Class Order Family Genus Species Scientific Name Most specific – 1 organism Nomenclature – Scientific Names • • • • • • • Binomial Nomenclature – 2 names Originated by Carolus Linnaeus Names are in Latin Italicized First Name – Genus (Capitalized) Second Name – Species ***In order to mate and produce fertile offspring all groups must be identical including the species Name the Genus and Species for the following: • • • • • • • Felis domestica Felis leo Felis tigris Homo sapiens Homo erectus Canis lupus Canis domestica
