Here's a breakdown:

* Animal cells: Typically range in size from 10 to 100 micrometers (µm).

* Bacteria cells: Typically range in size from 0.1 to 10 micrometers (µm).

Therefore, animal cells can be 10 to 100 times larger than bacteria cells.

This size difference is due to the complexity of animal cells, which contain many specialized organelles and structures that bacteria lack.
