ppt japon lol Flashcards
3 parts of flagella
Filament
Hook
Basal Body
chemical stimuli
chemotaxis
Light stimuli
Phototaxis
if a flagella moves clockwise it
tumbles
if a flagella moves in a smooth linear direction it
runs
Internal flagella,
enclosed in the space
between the outer
sheath and the cell
wall peptidoglycan
periplasmic flagella
Which of the following best describes the action of
the prokaryotic flagellum?
A. It whips back and forth to move the cell
B. It extends an contracts to move the cell
C. It rotates to move the cell
D. It attaches to the environment and pulls the cell
E. It is capable of all of the above
C
Function in adhesion
to other cells and
surfaces
fimbriae
pili is only found in what type of cells
gram negative cells
it Functions to join bacterial cells for partial DNA transfer
called conjugation
Pili
Protect cells from dehydration and nutrient loss
Inhibit killing by white blood cells by phagocytosis,
contributing to pathogenicity
Glycocalyx
function in cell
wall maintenance and
enlargement during cell division;
move cations across the cell
envelope; stimulate a specific
immune response
TEICHOIC & LIPOTECHOIC
the outer membrane of a negative cell has
Lipopolysaccharides
this regulate molecules entering & leaving cell
porin
which cell is less penetrable
Gram negative cell wall
Which of the following is NOT found in the
Gram-Negative cell wall structure?
A. Porins
B. Teichoic Acids
Periplasmic Space
Lipopolysaccharides
Peptidoglycan
B
Providing site for energy reactions, nutrient processing,
and synthesis
cell membrane
the cytoplasm is 70-80% water
bacterial cell
Used in genetic engineering -
readily manipulated and
transferred from cell to cell
plasmids
bacterial ribosome is made out of
60% rrna & 40% protein
Bacterial cell can use them when environmental
sources are depleted
inclusions and granules
this is the return to its vegetative growth
Germination
If you discover that the bacterium you’re studying
stores phosphate, which of the following would
you expect to contain the stored phosphate?
A. Granules
B. Ribosomes
Plasmids
Lipopolysaccharides
Endospores
a
Variation in cell shape
and size within a
single species – often
occurs in response to
the environment
pleomorphism
classification systems for prokaryotes
Microscopic morphology
Macroscopic morphology
Bacterial physiology
Serological analysis
Genetic and molecular analysis
colony appearance
Macroscopic morphology
presence of products that
are the result of bacterial metabolism
Bacterial physiology
basically antibody binding
properties
Serological analysis
– identification
based on the presence of genetic materials or
molecules
Genetic and molecular analysis
Classification based on genetic information
PHYLOGENETIC
a collection of bacterial cells which
share an overall similar pattern of traits
species
a culture derived from a
single parent that differs in structure or
metabolism
strain or variety
a subspecies that can show differences
in antigenic makeup
type
Round bacterial cells growing in irregular clusters
would be best described as:
A. Streptococci
Streptobacilli
Staphylococci
Tetrads
Sarcinae
Pleomorphic
C
