What does interferon type II do? ......answer.....Direct
recruitment or other innate system responses and
signal for adaptive cell response
Describe a capsule/glycocalyx ......answer.....Sticky,
composed of thick layers of proteins and
polysaccharides
What does a capsule provide?
......answer.....Mechanism of adhesion to host cells
and other bacteria
Describe how prokaryotic cells store genetic
material.
,2|Page
......answer.....Non membrane bound nucleoid region.
List TWO similarities between prokaryotic and
eukaryotic cells. ......answer.....plasma membrane,
contain ribosomes to make proteins
Describe how eukaryotic cells store genetic
information.
......answer.....Membrane bound nucleus
Describe the role of the cell wall in a bacterial cell.
......answer.....responsible for the shape of a cell,
provides protection against environmental stressors
,3|Page
List THREE accessory structures that facilitate
movement and attachment in bacteria
......answer.....capsule, fimbriae, flagella
Compare and contrast Gram-positive and Gram-
negative bacteria regarding the amount of
peptidoglycan present in their cell walls
......answer.....Gram-positive bacteria have a thick
layer of peptidoglycan, and Gram-negative bacteria
have a thin layer of peptidoglycan
, 4|Page
Describe the Gram-stain process ......answer.....First,
a sample of the bacteria is stained with a crystal
violet dye and iodine. Next, the sample is rinsed with
alcohol to remove the unbound dyes. Finally, the
sample is stained a second time with a red dye. The
properties of the cell wall will determine how the
dyes change the color of the cell, and determination
of the type of bacteria can be made when the stained
cells are viewed under a microscope.
List and describe the most common bacterial shapes.
