  1. Identification, Variation, & Adaptation Big Ideas

  2. 8 Major Categories of Classification Domain • Species is the most specific Dear King Phillip Came Over For Good Soup

  3. 6th Grade Review • All living things are classified into taxonomic groups: the largest and broadest umbrella is the domain • The 3 Domains for the Taxonomic Classification of Living Things are as follows: • Bacteria • Archaea • Eukaryota

  4. 6th Grade Review • Characteristics are used to classify organisms into kingdoms • Type of cell (prokaryotic or eukaryotic) • Number of cells (unicellular or multicellular) • Food source (autotrophic or heterotrophic) • Mode of reproduction (sexual or asexual) • There are currently 6 kingdoms –The 6 Kingdoms of living things are as follows: • Archaebacteria • Eubacteria • Fungi • Protists • Plants • Animals

  5. Eubacteria Archeabacteria Most Asexual, some Sexual

  6. Eukaryotic vs. Prokaryotic • Has a nucleus • You have a nucleus and are Eukaryotic • Pro means NO • No nucleus

  7. Multicellular vs. Unicellular • Organisms with more than 1 cell • 1-celled organism

  8. Heterotrophs vs. Autotrophs • Eat other organisms to get energy • Make their own energy (food) through photosynthesis

  9. Sexual Reproduction vs. Asexual Reproduction • 2 parents • Diverse offspring • 1 parent • Uniform offspring

  10. Taxonomic Classification • BrainPop – • Classification only First 1:35 • Six Kingdoms • List the 3 currently recognized domains? • Bacteria • Archaea • Eukarya • List the 6 currently recognized kingdoms? • Bacteria • Archaea • Protist • Fungi • Plant • Animal

  11. Taxonomy Classification • Taxonomy– the science of classifying (naming) organisms • Binomial Nomenclature • developed by Carolus Linnaeus • 2-word naming system (genus and species) • Examples: • Felisconcolor (mountain lion) • Ursusarctos (brown bear) • Homo sapiens (humans) • Pantheraleo (lion) • Pantheratigris (tiger) • Recognize and properly write a scientific name: Homosapiens, or Homo sapiens, or H. sapiens • 1st word is Capitalized –Genus • 2nd word is lowercase —species • Underline • Italicize • Abbreviate the genus (first name) (P. tigris or P. leo)

  12. Adaptations • Explain how each adaptation is used by an organism to enhance its survival… • Hollow bones • Dense bones • Xylem • Plant storage bulb • Pholem • Gills • Lungs • Migration • Hibernation

  13. Natural Selectionvs.Selective Breeding View BrainPop Natural Selection through 2:48

  14. Natural Selection • Changes in genetic traits that occur over many generations due to environmental factors for survival or reproduction • Temperature, rainfall, predator-prey, attracting mates

  15. Natural Selection • Galapagos Medium Ground Finch • Now several species of finch because the variety of food sources found in different areas

  16. Natural Selection ….the result • Peppered Moths • During the Industrial Revolution trees were covered with soot from smoke

  17. Selective Breeding • the process of HUMANS choosing specific plants or animals to breed for desirable genetic traits • Domesticated animals • Crops

  18. Selective Breeding • Domesticated animals are bred for…. • Mild temper • Color • Speed

  19. Selective Breeding Farm animals are bred for… Lay most eggs More meat Produce more milk Mild temper No horns Strength

  20. Selective Breeding Plants such as fruits, vegetables, and garden flowers are bred for… To produce more crop To produce bigger crop Resistant to pests and diseases Drought-resistant

  21. Leafy Sea Dragon Selective Breeding or Natural Selection …you decide Cabbage Varieties

  22. Leafy Sea Dragon Selective Breeding or Natural Selection …you decide Cabbage Varieties SELECTIVE BREEDING NATURAL SELECTION

  23. Tesonite (Corn) Selective Breeding or Natural Selection …you decide Bengal Cat

  24. Tesonite (Corn) Selective Breeding or Natural Selection …you decide SELECTIVE BREEDING SELECTIVE BREEDING Bengal Cat

  25. Puggle Selective Breeding or Natural Selection …you decide Liger

  26. Puggle Selective Breeding or Natural Selection …you decide Liger SELECTIVE BREEDING SELECTIVE BREEDING

  27. zebra Selective Breeding or Natural Selection …you decide Eyes that rotate in all directions

  28. zebra Selective Breeding or Natural Selection …you decide Eyes that rotate in all directions NATURAL SELECTION NATURAL SELECTION

  29. Extra Time • BrainPops • Gills • Hibernation • Migration • Camouflage
