- Prokaryotic Cells
- These are single celled organisms
- e.g. bacteria like e-coli
- Prokarytoic cells are less than 2ym and 50x smaller than eukaryotic
- Slime Capsule
- Some prokaroytoic cells secrete this
- It helps to protect the bacteria from attack by the immmune system
- Plasmid
- Small loops of DNA that aren't part of the main DNA
- DNA
- This floats free in the cytoplasm as prokaryotic cells don't have a nucleus
- It is one cioled up starnd and attached to histone proteins
- Flagella
- This a long hair like structure that rotates to move the cell
- Cytoplasm
- This contains ribosomes but and smaller than in eukaryotic cells
- Cell Surface Membrane
- Mainly made of lipids and proteins and it controls themovement of substance in and out of the cell
- Cell Wall
- supports the cell and prevents it changing shape
- It's made of a polymer called murein which is a glycoprotein
- These are single celled organisms
