WebOct 21, 2015 · As the ratio gets smaller, it takes longer for items to diffuse. Explanation: When the cell increases in size, the volume increases faster than the surface area, because volume is cubed where surface area is squared. When there is more volume and less surface area, diffusion takes longer and is less effective.
