  1. CLASSIFICATION OF SPECIES

  2. CLASSIFICATION OF SPECIES • What is taxonomy? • Who developed the system? • How does the system work? • What are these groups called? • The scientific system of classifying living organisms • CarolusLinneaus • Organisms are grouped based on similarities between them • Taxa (singular-taxon)

  3. CLASSIFICATION OF SPECIES • How are the taxa organized? • Names & order of taxa… • From largest group (least specific) to smallest group (most specific) • Domain • Kingdom • Phlyum • Class • Order • Family • Genus • Species

  4. CLASSIFICATION OF SPECIES • What scientific names are used for organisms? • Examples: • Genus and species (binomial nomenclature) • Acer rubrum (maple) (red) - Red Maple • Felisdomesticus (cat) (domestic) – House cat

  5. CLASSIFICATION OF SPECIESCircle our Genus and species

  6. Review Vocabulary before we get started • Autotrophic • Heterotrophic • Decomposer • Multicellular • Unicellular • Aerobic environment • Anaerobic environment • Absorptive Heterotroph • Ingestive Heterotroph • Producer • Consumer

  7. CLASSIFICATION OF SPECIES • Domain Bacteria contains… • Characteristics of Kingdom Eubacteria: • Kingdom Eubacteria • Prokaryotic • Have cell walls made of protein • May be autotrophic or heterotrophic • Found in all habitats except harsh ones • Some cause disease

  8. CLASSIFICATION OF SPECIES • Why are members of Kingdom Eubacteria important? • Decomposers • Nitrogen fixers • Commercially important

  9. CLASSIFICATION OF SPECIES • Domain Archaea contains… • Characteristics of Kingdom Archaebacteria… • Kingdom Archaebacteria • Prokaryotic • Have cell walls made of protein • May be autotrophic or heterotrophic • Live in harsh environments • 1st cellular organisms

  10. CLASSIFICATION OF SPECIES • Kingdom Archaebacteria members are found in… • Scientists believe that Archaebacteria are … • Sewage treatment plants • Volcanic vents or hot springs • Long-frozen ice • More related to the members of Domain Eukarya than Domain Bacteria

  11. What evidence did scientists use to determine the archaebacteriais most similar to eukaryotes?

  12. CLASSIFICATION OF SPECIES • Domain Eukarya contains… • What all members have in common… • Kingdoms: • Protista • Fungi • Plantae • Animalia • They are eukaryotic

  13. What does Eukaryote mean? • How will you recognize it on your test? • What structure are you looking for?

  14. CLASSIFICATION OF SPECIES • Characteristics of Kingdom Protista • Where do they live? • Most unicellular, some (algae) are multicellular • Some autotrophic, some heterotrophic • Some have cell walls made of cellulose • Some have chloroplasts • Mostly in water; some in moist soil or animal bodies

  15. CLASSIFICATION OF SPECIES • It is classified as a protist if it is not… • What are the most important protists? • A fungus, a plant or an animal • Phytoplankton and zooplankton

  16. CLASSIFICATION OF SPECIES • The characteristics of Kingdom Fungi are… • All members are multicellular except for yeasts • Absorptive heterotrophs; they are decomposers • Have cell walls made of chitin

  17. CLASSIFICATION OF SPECIES • The characteristics of Kingdom Plantae are… • All multicellular • All autotrophic • Cell walls made of cellulose • Have chloroplasts and a large central vacuole • Also called producers

  18. CLASSIFICATION OF SPECIES • The characteristics of Kingdom Animalia are… • All multicellular • All ingestive heterotrophs • None have cell walls or chloroplasts • Also called consumers

  19. CLASSIFICATION OF SPECIES • How were organisms first classified? • How are organisms classified now? • Grouped according to similarities in structure and environment they lived in • Similarities in DNA
