Cell Shape and Arrangement
Rod shaped bacteria are called
bacillus
phospholipid bilayer
What is the structure made up of peptidoglycan?
Binary Fission
type of bacteria that love heat
thermophiles
Wavy bacteria are called
spirillum
helps bacteria move through whip-like movements
flagella
This is the outermost layer of the cell wall and is attached to the peptidoglycan by a layer of lipoproteins
outer membrane
What is happening to a bacterial population during the stationary phase of growth.
growth rate = death rate
Type of bacteria that lives at high pressures
barophile
bacillus bacteria that are in chains are called..
streptobaccilus
After taking the top off the test tube, you should do this to keep create a positive pressure and keep things from falling into the test tube
flame the top of the test tube
These structures protect the cell from drying and helps them adhere to their environment (your teeth!)
slime layer
Why do bacteria not continue to grow exponentially?
run out of space, run out of nutrients
type of bacteria that live in pH of 0.1-5.4
acidophiles
Coccus that occur in pairs are called
diplococcus
type of pili that create a pathway for genetic material to be transferred during reproduction
conjugation
help bacteria stick to surfaces, helps to increase pathogenicity
attachment pili
agar slant
require oxygen, but only grow when oxygen concentrations are low
microaerophiles
clusters of coccus bacteria are called
staphylococcus
protective surface around bacteria, prevents the host from eating the bacteria
Dormant state of bacteria that is resistant to changes in the environment that would normally kill them
Endospores
What method could be used to isolate bacteria and grow them in a pure culture
streak plate
bacteria that do not use oxygen, and their metabolic processes stop in presence of oxygen
obligate anaerobes
