Typical prokaryotic cells are typically between 1 and 5 μm in diameter (about the size of a mitochondrion) whereas eukaryotic cells are between 10 and 100 μm in diameter.

Typical prokaryotic cells are typically between 1 and 5 μm in diameter (about the size of a mitochondrion) whereas eukaryotic cells are between 10 and 100 μm in diameter. This makes prokaryotic cells much smaller in size than eukaryotic cells; however, prokaryotic cells are still larger than viruses.
