Which of the following is present in a prokaryotic cell? Chloroplast, Nucleus, Ribosome, Centriole.
Answer:
The answer is ribosome.

Prokaryotes lack membrane bound organelles, so chloroplast and nucleus are absent.
Centriole is present only in animal cell.
Protein making machinery is present in prokaryotes: therefore ribosome is the right choice.
