Cell structures-prokaryotic cells Flashcards
1
Q
cell wall function
A
it is the cell’s rigid outer covering made of peptidoglycan.
provides the cell with strength and support.
2
Q
slime capsule
A
-protective slimy layer
-helps the cell to retain moisture(prevent dehydration) and adhere to surfaces
3
Q
plasmid DNA
A
circular pieces of DNA
allows for resistance to antibiotics
4
Q
flagellum
A
a tail like structure which rotates to move the cell
5
Q
pili
A
thin, hair-like structures which attach to other bacterial cells(allowing the exchange of plasmids)
6
Q
70S ribosomes
A
-composed of 2 subunits
-it is the site of protein synthesis
7
Q
mesosomes
A
-infoldings of the inner membrane
-its function is debated
8
Q
what other type of DNA(apart from plasmid DNA) does prokaryotic cells have?
A
circular DNA
