The particle surface-area-to-volume ratio is a measure of a fuel … The ratio between the surface area and volume of cells and organisms has an enormous impact on their biology, including their physiology and behavior. For example, many aquatic microorganisms have increased surface area to increase their drag in the water. This reduces their rate of sink and allows them to remain near the surface with less energy expenditure. halley came to jackson songWebsurface or membrane in opposite directions. Gas exchange is needed to provide cells with enough oxygen for cellular respiration, and to remove the carbon dioxide that the cells produce.
