Surface Area to Volume

Ratio governing cellular exchange efficiency.

Formula

SA:V=surface areavolumeSA:V = \frac{\text{surface area}}{\text{volume}}

Variables

Example

Smaller cells ⇒ higher ratio

Did You Know?

The surface-area-to-volume ratio is why cells stay microscopic and why elephants have such big ears to shed heat.
