IB Biology A2.2.4 Structures common to all cells
Practise recognising the cell structures shared by prokaryotes and eukaryotes, especially when comparing cells in short answers and MCQs.
How this is tested
- distinguish shared structures from features found only in some cell types
- compare prokaryotic and eukaryotic cells using common DNA, ribosomes and cytoplasm
- select the organelle or component present in all cells from close distractors
