Surface Area/ Volume Ratio Limits Cell Size

At some point of the cells growth, the surface area/volume ratio becomes so small that the surface area is too small to supply raw materials to its volume. Here, the cell cannot get any bigger.

...

The greater the surface area of the cell, the more raw materials that can enter inside the cell at once.

A cell is a metabolic compartment in which many chemical reactions take place - the bigger the volume of the cell, the more chemical reactions take place.

Each unit of the cells volume needs a specific amount of surface area to supply its metabolism with raw materials. The amount of surface area available to each unit of the cell depends on the size of the cell.

As a cell grows, it's surface area/volume ration decreases.

Explain how surface area/volume ratio limits cell size?

Raw materials needed for the cell to metabolize can only enter the cell through its cell membrane.
