Chapter 3 Flashcards
what is the Slime layer?
Prevent from drying out
Help with attachment
Is usedful in biofilm
what is a Capsule?
Virulent factor
Help avoid immune system
Make phygicytosis difficult
what are Biofilms
Multiple types of micriobs living tigether
Example
Water, catethers, dental plaque
All cells have what?
Ribosomes
Cytoplasm
Ds dna
Cell membrane
what is the purpose of Flagella?
Is for movement
what is an Endoflagella?
Wraps around bacterial cell
Crockscrew
Fimbria is composed of what?
Sticky bristles
Used for attachment
Heloful in biofilm formation
Pili
Transfers genes located in dna
In a process called conjugation
what is a Selectively permeable?
Allows things yo pass thru but not everything
Teichoic acids, lipoteichoic acids
Provide cell stability
Gram negative
Thin layer of peptideglycan
Lps-can cause inflammation in the host
Mycoplasma
Lack of bacterial cells
Cytoplasm
Contains
Nucleiod-dna
Ribosomes-make protiens
Cytoskeleton -structure system
Inclusioms -storage walls
peritrichous
has flagella all over
monotritochous
single flagella
lofultrichous
tuft- looks like hairs
amphitrichous
flagella on both ends
gram negative
turns pink
thin peptidoglycan
periplasmic layer
Gram positive
thick peptidoglycan layer
teichoic acids
what attacks peptidoglycan
prodozoan
what are lysosomes
breakdown
what bacteria causes a waxy outerlayer
mycobacteria
what is a bacterial chromosome
haploid
has circular DNA
what is a plasmid?
are self-replicating snippets of DNA
what does LPS cause?
inflammation in the host
cells grow up in?
up in size
cells reproduce up in?
up in number
prokaryotes
has no membrane organelles
divides by binary fission
eukaryotes
have membrane-bound organelles
divided by miosis and mitosis
