Physical barrier that protects agains mechanical damage, such as stopping it bursting when it takes in water by osmosis, and excludes certain substances
cell wall
1 of 8
Protects bacterium from other cells and helps groups of bacteria to stick together for future protection. also stops cells from drying out
slime capsule
2 of 8
acts as a differentially permeable layer which controls the entry and exit of chemicals
cell membrane
3 of 8
for locomotion - aids movement of bacterium because its rigid, corkscrew shape and rotating base help the cell spin through fluids
flagellum
4 of 8
large circle of DNA - possesses the genetic information for the replication of bacterial cells
nuclear material
5 of 8
possesses the genes that aid the survival of bacteria in adverse conditions, e.g. produces enzymes which break down antibodies
plasmid
6 of 8
smaller than in eukaryotic cells - used in protein synthesis
ribosomes
7 of 8
jelly-like and contains enzymes and other soluble materials
cytoplasm
