Explain how surface to volume ratios limit the size of a cell
Homework Answers
ans-
The factors limiting the size of cells include: Surface area to volume ratio (surface area / volume) Nucleo-cytoplasmic ratio. Fragility of cell membrane. The reason that the cell can grow to a certain limit is its surface area to volume ratio.
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.
As a cell gets bigger there comes a time when its surface area is not large enough to meet the demands of the cell volume and the cells stop growing. As a cell grows larger in volume its metabolic demands increase faster than the surface area's ability to meet those needs , hence a maximum size is reached . Plenty of oxygen can diffuse into a small cell but not a large one.

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. 2.
