  1. Biology Biodiversity

  2. Content Standard 3.1 Different species might look dissimilar, but the unity among organisms becomes apparent from an analysis of internal structures, the similarity of their chemical processes, and the evidence of common ancestry.

  3. All living things on Earth have some traits in common and some traits that make them different.

  4. Traits of organisms can be used to "classify" them - put them in groups

  5. "Classify" these shapes into three groups?

  6. Shape • rectangle • circle • oval

  7. What characteristic can be used to separate the rectangles into 2 groups?

  8. Classification Lab

  9. Classification Lab Use "shape" to put the objects in 2 large groups

  10. Classification Lab 2. Use a different characteristic to separate each large group into 2 groups

  11. Classification - 3 min

  12. Carolus Linnaeus is considered to be the father of our modern system of classification.

  13. Today's classification • system is divided • into these groups: • Kingdom • Phylum • Class • Order • Family • Genus • Species

  14. 6 Kingdoms of Living Things

  15. Archaebacteria All Archaebacteria live without oxygen(anerobic)...

  16. Archaebacteria and obtain their energy from inorganic molecules or from light (autotrophic)...

  17. Archaebacteria for this reason archaebacteria are also known as EXTREMOPHILES.

  18. Eubacteria Kingdom Type of cells: Prokaryotic Cellular organization: Unicellular/Colonial Type of reproduction: Asexual by binary fission Food production: Autotrophic

  19. Protista Kingdom

  20. Protista Kingdom Type of cells: Eukaryotic Cellular organization: Unicellular/Colonial Type of reproduction: Asexual by mitosis Food production: Heterotrophic or Autotrophic

  21. Fungi Kingdom

  22. Fungi Kingdom Type of cells: Eukaryotic Cellular organization: Multicellular Type of reproduction: Sexual/Asexual Food production: Heterotrophic by absorption

  23. Plant Kingdom

  24. Plant Kingdom Type of cells: Eukaryotic Cellular organization: Multicellular Type of reproduction: Sexual/Asexual Food production: Autotrophic by photosynthesis

  25. Animal Kingdom

  26. Animal Kingdom Type of cells: Eukaryotic Cellular organization: Multicellular Type of reproduction: Sexual/Asexual Food production: Heterotrophic by ingestion

  27. What kingdom do viruses belong to?

  28. Viruses are much smaller and less complex than cells. Viruses consist of either DNA or RNA enclosed in a protein coat called a capsid. Viruses do not grow.

  29. Viruses have no nucleus, cytoplasm, or membranes. Viruses do not carry out cellular functions. Viruses do not generate metabolic energy.

  30. Viruses are obligate intracellular parasites, meaning that they require a host cell to reproduce.

  31. In short, viruses are not alive!!

  32. 3 basic types of viruses: Bacteriophage

  33. 3 basic types of viruses: "Bacteria Eater" Bacteriophage

  34. 3 basic types of viruses: Adenovirus

  35. 3 basic types of viruses: The common cold Adenovirus

  36. 3 basic types of viruses: Retrovirus

  37. 3 basic types of viruses: Human Immunodeficiency Virus H I V Retrovirus

  38. The 3 Types of Viruses Bacteriophage Adenovirus Retrovirus

  39. Phylogeny Reconstruction of the evolutionary histories of organisms

  40. Phylogeny A phylogenetic tree shows a hypothesis about relationships that exist among groups of organisms.

  41. #1 Evolution - 2 min

  42. The closer two organisms are to a branch, the closer their relationship. Phylogeny

  43. Think of a branch as the place where a gene pool is separated. Phylogeny

  44. Line length indicates degree of change, NOT length of time. Phylogeny

  45. Phylogenetic trees are based on four things:

  46. 1. The Fossil Record

  47. Any trace of a long-dead organism Fossil
