70s
Proteinsynthesis
Name the function of the Cytoplasm.
Site of chemical reactions.
Name the function of the capsule.
A sticky layer that creates protection from other cells.
Can stick to other bacterial cells for further protection and reproduction.
Name the function of the Plasmid.
The plasmid contains genes that aid survival, resistant from antibiotics, produce enzymes that break down antibodies.
Name the function of the Flagellum.
Helps movement in the cell.
Has a corkscrew shape and rotating bottom.
Not all prokaryotic cells have these.
What is a prokaryotic cell ?
Does not contain membrane bound organelles.
Name the function of the mesosome ?
In the folding of the cell membrane.
Contains enzymes for respiration.
ATP production.
Name the function of the pilus
Aid adhesion to other cells
What is the DNA called in this type of cell and what shape is it ?
Circular nucleoid
