  1. Unit C Key Terms

  2. C31-The Range of Disease • Disease-a breakdown in the structure or function of a living thing

  3. C30-It’s Catching! • Infectious-disease that is caused by a pathogen that invades the body (bacterium, virus, fungus, protist)

  4. C33-From One to Another • Carrier-a person that carries a disease but never develops symptoms

  5. C33-From One to Another • Quarantine-forced isolation of people to prevent the spreading of disease

  6. C33-From One to Another • Vector-organism (other than a person) that spreads disease-causing pathogens

  7. C37-The History of the Germ Theory of Disease • Germ theory of disease-the idea that diseases are caused by microbes (“germs”)

  8. Introduction to Cells • Cell- “the building block of life;” the smallest unit of structure and function in an organism

  9. Introduction to Cells • Cell theory-statement of scientific knowledge about cells: • (1) All living things are made of cells. • (2) All cells come from other cells. • (3) Cells are the basic unit of structure and function in living things.

  10. Cellular Organization • Organism-living thing

  11. C41-A Cell So Small • Unicellular-organism made of one cell (examples: bacteria, protists, yeast)

  12. C41-A Cell So Small • Multicellular-organism made of more than one cell (examples: plants, animals)

  13. C35-A License to Learn • Magnify-to make an object appear larger

  14. C42-A Closer Look • Organelle-small structure that does a special job for the cell

  15. C42-A Closer Look • Cell membrane-part of ALL cells that separates the cell from the environment and controls what moves in and out of the cell

  16. C42-A Closer Look • Cytoplasm-jelly-like material that fills the inside of ALL cells

  17. C42-A Closer Look • Nucleus-part of some cells that is the “control center” of the cell and directs cell activities

  18. C44-Who’s Who? • Microbe-microscopic structure that often causes disease (virus, bacterium, protist)

  19. C44-Who’s Who? • Classify-to put things into groups based on what they have in common

  20. C45-The World of Microbes • Bacteria-microscopic single celled organism without a nucleus

  21. C45-The World of Microbes • Protist-microscopic single celled organism with a nucleus

  22. C45-The World of Microbes • Virus-microscopic non-living structure that often causes disease

  23. C47-Reducing Risk • Petri dish-equipment used to grow microbes

  24. C49-An Ounce of Prevention • Antibiotic-chemical that kills bacteria

  25. C49-An Ounce of Prevention • Vaccination-medicine that can prevent disease by “training” the immune system to fight its cause

  26. C51-The Full Course • Full course-the length of a prescription for an antibiotic

  27. C51-The Full Course • Infection-when the body is invaded by a pathogen

  28. C51-The Full Course • Resistant-bacteria that is not easily killed by an antibiotic

  29. C53-Modern Outbreaks • Emerging disease-a disease that is new in the human population
