PROKARYOTIC CELL STRUCTURE - AQA Biology A-level/AS

?
Plasma Membrane
made of lipids and proteins and controls movement of substance in and out of the cell
1 of 7
Cell Wall
made of murein (glycoprotein). prevents the organism from changing shape
2 of 7
Capsule (bacteria)
made of slime and helps protect the bacteria from attcak by the immune system.
3 of 7
Plasmids
small loops of DNA. contain genes for things like antibiotic resistance. not always present in all prokaryotic cells
4 of 7
Circular DNA
long coiled up strand of DNA. Not attached to any histone proteins
5 of 7
Flagellum
hair like structure that spins to allow the organism to move
6 of 7
cytoplasm
no membrane bound organelles. contains ribosomes but they are 70S type
