Prokaryotes are much simpler than eukaryotes, animal and plant cells. You will need to know the parts and functions of a typical prokaryote.
Our example is a bacteria cell
Cell Membrane – Controls what enters and leaves the cell
Cell Wall – Supports structure and provides protection
Cytoplasm – Chemical reactions take place here
Ribosomes – Protein synthesis happens here
Flagella – Helps the bacteria move (locomotion)
DNA – Controls the activity of the cell
Plasmids – Small ring of DNA that might benefit the bacteria cell e.g. antibiotic resistance
You will notice there are some similar parts to the animal and plant cell but with a few key differences.
- They have DNA but not enclosed in a nucleus
- Not all bacteria have flagella
- The amount of plasmids will vary with each bacteria
