  1. what are fine, proteinaceous hairlike bristles, emerging from the cell surface
    fimbriae
  2. what has the function in adhesion to other cells and surfaces attaches to the area it wants and sticks
    fimbriae
  3. what bacteria is made of protein and each bacteria has different protein make up that helps identify surfaces
    fimbriae
  4. what is a rigid tubular hollow structure made of pilin protein
    pili
  5. what is found only in gram- negative cells (e.coli)
    pili
  6. what is anti-biotic resistant and form tunnel from donor fimbriae to recipent fimbriae to transfer DNA
    pili
  7. what has the function to join bacterial cells for partial DNA transfer called conjugation
    pili
  8. what is the coating of molecules external to the cell wall made of sugars and proteins (exceptions)
    glycocalyx
  9. what are the two types of glcocalyx

  10. what glycocalyx is loosely organized and attached can wash off
    slime layer
  11. what glycocalyx is highly organized, tightly attached and does not wash off
    capsule
  12. what protects cells from dehydration and nutrient loss helps in survial
    function of glycocalyx
  13. what is inhibited by white blood cells by phagocytosis (eats other cells) contributing to pathogenicity (activity to cause disease/infection)
