How many times larger is a eukaryotic cell than a prokaryotic cell

The eukaryotic cell is 10 to 100 times larger than the prokaryotic cells.

Explanation:

The eukaryotic cell is 10 to 100 times larger than the prokaryotic cells. The prokaryotic cells are primitive, simpler in structure. The eukaryotic cells are complex in structure and have different adaptation for various cellular activities.  

All the cells have cytoplasm, cell membrane, nucleus. In prokaryotes, the nucleus is not well defined and no other membrane-bound organelles.

e.g. bacteria, archaea.

The diameter of prokaryotic cells is smaller than the eukaryotic cells. Because the transport of ions and cell division is faster in it. Its diameter ranges from 0.1 micrometers to 5.0 micrometers. While eukaryotic cell diameter is 10 to 100 micrometers.  

The small size of the prokaryotes is an advantage to its cellular processes whereas the eukaryotic cells are larger.  Because it has to adapt to the function of different cell organelles present in it.
