Presentation Transcript

  1. BacteriaStructure • Prokaryotic Cell • (NO membrane-bound Nucleus) • Cell Wall • DNA Found in Cytoplasm • Contain Ribosomes • Flagellum for Movement • Three Types of Shapes • Sphere – Coccus • Rod – Bacillus • Spiral - Spirillum

  2. Virus Structure Need a Host Cell to Live and Multiply No Nucleus No Organelles No Cell Membrane Can Only Be Seen with the Electron Microscope Many Shapes Diseases Common Cold Influenza AIDS Polio Viruses that infect bacteria

  3. Movement Flagellum • Contain Chloroplast • Produce Oxygen • Movement Flagellum • Contain Chloroplast • Produce Oxygen • Live in Colonies Euglena Protists Unicellular Contains Nucleus Cause: Malaria, Dysentery, African Sleeping Sickness Volvox Movement Pseudopod “False Foot” • Movement Pseudopod “False Foot” Amoeba • Movement • Cilia Paramecium

  4. Amoeba Pseudopod: “False Foot” Used for movement and to surround its food and draw it into its cytoplasm

  5. Contractile Vacuole: Pumps water out of the cell to prevent it from bursting Oral Groove: Channel where food is taken in “mouth” Paramecium

  6. Eyespot : Senses and responds to light Uses flagellum to move toward the light to carry on photosynthesis Euglena

  7. Volvox

  8. Disease Change that disrupts the NORMAL function of the body Non- Infectious Disease that CAN NOT be spread from one organism to another Infectious Caused by: Exposure to chemicals in the environment or Lifestyle choices or Inherited traits Pathogen Microbe that causes disease Contagion Disease that spreads from one organism to another Carrier (Human) Vector (Animal)

  9. Non-Infectious or Infectious Diseases

  10. Infectious Diseases Caused By Pathogens

  11. Infectious Diseases Spread By Vector or Carrier

  12. How far a disease has spread Outbreak Epidemic Pandemic

  13. ImmunityOrganism’s Resistance to Infection or Disease Active Immunity Vaccination Against The Disease Get The Disease Antibodies From Infected Organism Antibodies From Mother Passive Immunity

  14. Vaccines, Antibiotics and AntibodiesWhat is the Difference? Vaccines Antibiotics Antibodies Drugs that kill bacteria or prevent their production. Chemical produced by the body to destroy pathogens. Weakened or dead pathogen that help the immune system fight a disease. Work by destroying the bacteria’s cell wall. Can be from a bacteria or a virus.
