Detailed explanation-1: -Prokaryotic cells are larger in size as compared to eukaryotic cells. Eukaryotic cells have more complex structure than prokaryotic cells. Viruses, fungi, and alga are examples of eukaryotic cells. Therefore, prokaryotic cell is the smallest in the given case.

Detailed explanation-2: -Viruses are much smaller than prokaryotes, ranging in size from about 20–300 nanometers (nm), though some can be larger. Prokaryotes are typically 0.5–5.0 micrometers (µm) in length.

Detailed explanation-3: -A virus is about ten times smaller than a typical bacteria cell, and at least 100 times smaller than a typical eukaryotic cell. A virus is about ten times smaller than a typical bacteria cell, and at least 100 times smaller than a typical eukaryotic cell.

Detailed explanation-4: -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-5: -At 0.1–5.0 m in diameter, prokaryotic cells are significantly smaller than eukaryotic cells, which have diameters ranging from 10–100 m (Figure 3). The small size of prokaryotes allows ions and organic molecules that enter them to quickly spread to other parts of the cell.
