8. Fill in the comparison table. Write YES or NO for each cell part:

Cell Part Comparison:

Nucleus: Animal cells _____ Plant cells _____

Cell membrane: Animal cells _____ Plant cells _____

Cytoplasm: Animal cells _____ Plant cells _____

Cell wall: Animal cells _____ Plant cells _____

Chloroplasts: Animal cells _____ Plant cells _____

9. Explain why plant cells have chloroplasts but animal cells don't:

10. Which cell is usually more regular in shape?

Plant cells (because they have a cell wall)
