bacterial cells Flashcards
1
Q
how do prokaryotic differ from eukaryotic cells
A
- smaller in size
- cytoplasm that lacks in membrane bound organelles
- smaller ribosomes
- no nucleus and have circular bacterial chromosome instead
2
Q
what does the cell wall in prokaryotic cells contain
A
glycoprotein called murein
3
Q
components of prokaryotic cells
A
plasmids
capsules
flagella
pili
mesosomes
4
Q
what is a mesosome
A
cell membrane that contains folds
5
Q
plasmid structure
A
small, circular DNA molecules separated from chromosomal DNA
6
Q
plasmid function
A
- carry genes for specific traits
- can be exchanged between bacteria
7
Q
flagella structure
A
long, whip like appendages made of protein flagellin
8
Q
flagella function
A
enable moment via rotation
9
Q
pili structure
A
thread like structures on the surface of some bacteria that enables them to attach to other celles
10
Q
capsule composition
A
polysaccharides or glycoproteins
11
Q
capsule function
A
- protects against phagocytosis
- aids in adhesion to surfaces
12
Q
cell division of prokaryotes
A
binary fission
