Which of the cels below has the largest ratio of surface area to volume? click the blue box next to the correct answer.

Solution

Surface area to volume ratio is very important for a cell because any cell should have a larger surface in order to move stuff in and out quickly, but wants a small volume to move stuff across itself really quickly.

Mathematically, surface area is a squared dimension whereas the volume is cubic dimension. Therefore if there is an increase in area of a cell, volume increases more than the area.

In the ration (surface area/volume), if the numerator is increased which is area in this instance, denominator which is volume increases even more. If there is an increase in denominator the ratio decreases mathematically.

From above we can say that smaller cells have higher surface area to volume ratio when compared to the larger ones.

Therefore in the given picture fourth cell or the first cell in second row is smaller in size and have larger surface area to volume ratio.
