Answer: D) Prokaryotes are only Single Celled
A prokaryotes are single celled or unicellular organism that do not have nucleus or other membrane bound organelle.
The size of prokaryotic cell normally ranges from 0.1 to 0.5 μm. The size of prokaryote are smaller than eukaryotes which ranges from 10–100 µm
