Explanation / Answer

16)- Option c is correct because prokaryotic cells possess 70S ribosome.

17)- option d is correct because gram negative cell wall resistance to penicillin.

18)- option c is correct because prokaryotic cells don't have cilia.

19)- option a is correct because cellulose is present in the cell wall of plant cell not prokaryotic cell.

20)- option d is correct because in this process cell wall not involved.
