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: -Mitochondria are typically round to oval in shape and range in size from 0.5 to 10 m.
Detailed explanation-3: -General size of eukaryotes is 5-100 micrometers.
Detailed explanation-4: -Prokaryotes are microscopic organisms belonging to the domains Bacteria and Archaea, which are two out of the three major domains of life.
Detailed explanation-5: -Cell Size. At 0.1 to 5.0 m in diameter, prokaryotic cells are significantly smaller than eukaryotic cells, which have diameters ranging from 10 to 100 m (Figure 4.2. 2). The small size of prokaryotes allows ions and organic molecules that enter them to quickly diffuse to other parts of the cell.
