Question

Cell Surface to Volume issues – this question asks students to become familiar with basic formulas used to calculate surface area and volume, and to understand how much surface area and volume change when the diameter of a cell (or organism) gets larger. It also gives practice in understanding the (confusing) concept of surface area to volume ratios. Finally, an important example of biological compensation for such matters is presented.
