Presentation Transcript

  1. Classification • Taxonomy is a branch of science that attempts to organize the many diverse forms of life • Linnaean system is most widely used • Carolus Linnaeus1707-1778

  2. How to Remember This • Dumb(Domain) • Kings (Kingdom) • Play (Phylum) • Chess (Class) • On (Order) • Fine (Family) • Green (Genus) • Sand (Species)

  3. What is a species? A group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding to produce FERTILE OFFSPRING Genus species Homo sapiens, Gorilla gorilla

  4. ISP 26.1

  5. The Three Domains andSix Kingdoms of Life • Based on DNA evidence three Domains are recognized • Shared derived characteristics enable these domains to be broken into six Kingdoms

  6. Bacteria and Archaea • Kingdom Bacteria • Prokaryotic: no organelles • Often disease causing • Archaea • Prokaryotic • Extremophiles • Live in weird habitats like hot springs and super cold environments

  7. Serial Endosymbiont Theory

  8. Protista • Diverse group of eukaryotic organisms • Most protists are unicellular. • Protist groups are predominately organized by feeding method plus other unique characteristics.

  9. Animalia • All multicellular • Heterotrophic nutrition by ingestion • Diploid adult • Reproduction is usually sexual • Embryonic development often used to taxonomically classify animal groups

  10. Fungi • Multicellular eukaryotes • Feed as heterotrophs by absorption (Saprotrophic) • Body called mycelium made up of hyphae • Sexually reproduce via spores (resist drying out)

  11. Plantae • Multicellular eukaryotes with at least a tissue level of organization • Cell wall • Autotrophic by photosynthesis; use chlorophyll a & b • Store food reserves as starch • Terrestrial (evolved on land).
