Question

What is the relation between volume and surface area of a cell

Answer 1

As cells increase in size, the surface area and volume do not usually increase proportionally to length. The greater the diameter of a single-celled organism, the lower the surface area to volume ratio. It is this relationship that restricts the size of a particular cell.

The relationship between the radius, surface area, and volume of a cell

Note that as the radius of a cell increases from 1x to 3x (left), the surface area increases from 1x to 9x, and the volume increases from 1x to 27x.
