→Factors Affecting Diffusion, Osmosis and Active Transport across an Exchange Surface
*Thickness - The thinner the [[membrane]] the more quickly [[diffusion]] can take place across the [[membrane]].
*[[Concentration Gradient]] - The greater the difference between the [[concentration]] on each side of the [[membrane]] the more quickly [[diffusion]] can take place across the [[membrane]].
*[[MitochondiaMitochondria]] - In cases of [[Active Transport|active transport]] [[Cell (Biology)|cells]] will have extra [[mitochondria]] to provide [[energy]] for this process.
