Correct answer: B. 70S
- A. 40S
- B. 70S
- C. 80S
- D. 60S
Explanation
All prokaryotes have the 70S (where S is the Svedberg unit used in ultracentrifugation) ribosomes while eukaryotes contain larger 80S ribosomes in their cytosol.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
