This cutaway is a scientific illustration, not a photograph. Colours distinguish structures; shapes and proportions are generalised. Embedded image labels remain visible.
Selected organelle: Cell membrane
Use the organelle menu or guide to read functions. The reference image is not an organelle-location test. Images show example cell types; cells vary with tissue and preparation.
Investigate and explain
- Compare both cell types and record four shared structures.
- Select the membrane and explain why a wall cannot replace it.
- Explain why a root cell may lack chloroplasts but still require mitochondria.

Assignment and explanation guide
Write a claim, support it with two observations from this activity, and explain one model limitation. Compare with a partner. A strong answer names the structures or processes, controls relevant variables and distinguishes the illustration from biological evidence.
