What is the smallest cell between a cheek cell an onion cell

What is the smallest cell between a cheek cell, an onion cell and a bacterial cell viewed under a microscope? Explain your response.

Solution

The diameter of a cheek cell when viewd under the microscope is 60 micrometres

The diameter of a onion cell when viewd under the microscope is 250-400 micrometers

The diameter of a bacterial cell when viewd under the microscope is 0.2 micrometres

Therefore the increasing order of size bacterial cell<cheek cell<onion cell. Thus a bacterial cell is the smallest.
