compare the shapes of the two cells check to see which diagram shows a nucleus check to see which diagram shows cytoplasm compare the number of vacuoles in the two cells
I gave my students this multiple choice question: A student examined diagrams of two different cells. One cell was prokaryotic, and the other cell was eukaryotic. What should the student do to identify a major difference between the diagrams?

Only one answer is correct among these 4 choices:
- compare the shapes of the two cells
- check to see which diagram shows a nucleus
- check to see which diagram shows cytoplasm
- compare the number of vacuoles in the two cells

Could you tell me which one is correct?

check to see which diagram shows a nucleus
