Structure Of Prokaryotic Cells Flashcards
1
Q
Capsule
A
- protects bacterium from other cells and helps groups of bacteria to stick together for further protection
- layer of polysaccharide
- serves as a barrier
2
Q
Cell-surface membrane
A
- acts as a differentially permeable layer
- controls the entry and exit of chemicals
3
Q
Pilli
A
- hollow, hairlike structures made of protein
- allow bacteria to attach to other cells
- allows the transfer of DNA
4
Q
Flagella
A
- used for locomotion
- purpose is motility
- flagella are long appendages which rotate
5
Q
Plasmid
A
- posseses genes that may aid the survival of bacteria in adverse conditions
- exists as a large circular piece of DNA and a few smaller circles of DNA
6
Q
Mesosome
A
- folds of the membrane where respiration takes place
7
Q
Cell wall
A
- maintains cell shape
- compromised of peptidoglycan or murein
