    Problem: List the main reason why a cell is forced to divide due to cell growth.

    The main reason why a cell divides into smaller cells when it grows is due to the surface area (SA) to volume ratio problem. When a cell grows, both its surface area and its volume increase -- obviously. However, mathematically, the volume increases faster than does the surface area. Therefore, the ratio of SA:volume is higher in smaller cells. As the cells get bigger, the SA:volume ratio gets lower and ...
