c31 the range of disease
C31-The Range of Disease
  • Disease-a breakdown in the structure or function of a living thing
c30 it s catching
C30-It’s Catching!
  • Infectious-disease that is caused by a pathogen that invades the body (bacterium, virus, fungus, protist)
c33 from one to another
C33-From One to Another
  • Carrier-a person that carries a disease but never develops symptoms
c33 from one to another1
C33-From One to Another
  • Quarantine-forced isolation of people to prevent the spreading of disease
c33 from one to another2
C33-From One to Another
  • Vector-organism (other than a person) that spreads disease-causing pathogens
c37 the history of the germ theory of disease
C37-The History of the Germ Theory of Disease
  • Germ theory of disease-the idea that diseases are caused by microbes (“germs”)
introduction to cells
Introduction to Cells
  • Cell- “the building block of life;” the smallest unit of structure and function in an organism
introduction to cells1
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.
cellular organization
Cellular Organization
  • Organism-living thing
c41 a cell so small
C41-A Cell So Small
  • Unicellular-organism made of one cell (examples: bacteria, protists, yeast)
c41 a cell so small1
C41-A Cell So Small
  • Multicellular-organism made of more than one cell (examples: plants, animals)
c35 a license to learn
C35-A License to Learn
  • Magnify-to make an object appear larger
c42 a closer look
C42-A Closer Look
  • Organelle-small structure that does a special job for the cell
c42 a closer look1
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
c42 a closer look2
C42-A Closer Look
  • Cytoplasm-jelly-like material that fills the inside of ALL cells
c42 a closer look3
C42-A Closer Look
  • Nucleus-part of some cells that is the “control center” of the cell and directs cell activities
c44 who s who
C44-Who’s Who?
  • Microbe-microscopic structure that often causes disease (virus, bacterium, protist)
c44 who s who1
C44-Who’s Who?
  • Classify-to put things into groups based on what they have in common
c45 the world of microbes
C45-The World of Microbes
  • Bacteria-microscopic single celled organism without a nucleus
c45 the world of microbes1
C45-The World of Microbes
  • Protist-microscopic single celled organism with a nucleus
c45 the world of microbes2
C45-The World of Microbes
  • Virus-microscopic non-living structure that often causes disease
c47 reducing risk
C47-Reducing Risk
  • Petri dish-equipment used to grow microbes
c49 an ounce of prevention
C49-An Ounce of Prevention
  • Antibiotic-chemical that kills bacteria
c49 an ounce of prevention1
C49-An Ounce of Prevention
  • Vaccination-medicine that can prevent disease by “training” the immune system to fight its cause
c51 the full course
C51-The Full Course
  • Full course-the length of a prescription for an antibiotic
c51 the full course1
C51-The Full Course
  • Infection-when the body is invaded by a pathogen
c51 the full course2
C51-The Full Course
  • Resistant-bacteria that is not easily killed by an antibiotic
c53 modern outbreaks
C53-Modern Outbreaks
  • Emerging disease-a disease that is new in the human population
