Explanation:
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: -Cell size in prokaryotes is 1-10 Mm, whereas the cell size in eukaryotes is.
Detailed explanation-3: -This means that between 100 and 1000 bacteria will fit in a straight line in 1 mm. Groups of bacterial cells, called colonies, are shown in Figure 1.2. Many, but not all, scientists think that prokaryotes evolved before eukaryotes and so are missing some cell components that eukaryotic cells possess.
