Detailed explanation-1: -Cell size. Typical prokaryotic cells range from 0.1 to 5.0 micrometers (m) in diameter and are significantly smaller than eukaryotic cells, which usually have diameters ranging from 10 to 100 m.

Detailed explanation-2: -They are organisms which do not have proper cellular organization i.e they lack cellular organelles and a nucleus and therefore small in size.

Detailed explanation-3: -Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and lack organelles. All prokaryotic cells are encased by a cell wall.

Detailed explanation-4: -An individual virus is called a virion. It is a tiny particle much smaller than a prokaryotic cell. Because viruses do not consist of cells, they also lack cell membranes, cytoplasm, ribosomes, and other cell organelles.

Detailed explanation-5: -But it is still a fundamental observable fact that the vast majority of bacterial cells are physically small and morphologically simple compared with the vast majority of eukaryotic cells.
