Question
What do prokaryotic cells have that eukaryotic cells do not?
A. Mitochondria
B. 70S ribosomes
C. Histones
D. Internal membranes
Markscheme
B
Examiners report
There were many comments on this question respecting the presence of 70S ribosomes in mitochondria and chloroplasts. Although this is true, B was still the best answer of the available choices, as all others were present only in eukaryotes.
