IB Biology A2.2.5 Prokaryote cell structure
Practise interpreting and drawing bacterial cells, labelling prokaryote structures and comparing them with eukaryotic organisation.
How this is tested
- label bacterial diagrams with cell wall, plasma membrane, ribosomes, plasmids and DNA
- distinguish prokaryotes by absence of a nucleus and internal compartmentalisation
- explain why bacterial DNA lacks nucleosomes using naked, looped DNA or no histones
