High surface-to-volume ratio

WebMay 28, 2015 · The surface-area-to-volume ratio or SA:V, is the amount of surface area of an organism divided by its volume. Assume that you are a spherical cell. Then SA = 4πr2 and V = 4 3 πr3 and SA V = 4πr² 4πr² × r 3 = 3 r This says that the bigger you get ( r increases), the less surface area you have for your size. WebApr 15, 2024 · An increased surface area to volume ratio also means increased exposure to the environment. More contact with the environment through the surface of a cell or an organ (relative to its volume) increases loss of water and dissolved substances. Why is a bigger surface area better?
