Describe the plasma membrane and its structure.
It is mainly made out of lipids and proteins. It controls the movement of substances in and out the cell.
1 of 6
Describe the structure of pili and its function.
They are short hair like structures. They help prokaryotes stick to other cells and can be used in the transfer of genetic material between cells.
2 of 6
Describe the slime capsule and its structure.
It helps to protect bacteria from attack by cells of the immune system.
3 of 6
Describe the circular DNA and plasmid and its function.
There is free floating DNA it isn't attached to any histone proteins. Small loops of DNA they contain genes for antibiotic resistance and they can be passed between prokaryotes (not always present in prokaryotes).
4 of 6
Describe the flagellum and its function.
It is a hair like structure that rotates to make the prokaryotic cell move. (not all prokaryotes have a flagellum)
5 of 6
Describe the cytoplasm and its function.
Has no membrane bound organelles it has ribsomes but they are smaller than those in eukaryotic cells.
