Definition Of Diffusion And Osmosis

While osmosis influences the distribution of nutrients and the release of metabolic waste products in animals.

Definition of diffusion and osmosis. Differences in function. When people discuss osmosis in biology it always refers to the movement of water. Osmosis is a type of diffusion that in biology is usually related to cells. In biology osmosis is defined as the net movement of water molecules through a semipermeable membrane e g.

The process of a solvent diffusing through a semipermeable membrane from an area of low solute concentration to an area of high solute concentration. Diffusion can occur through a cell membrane and the membrane allows small molecules like water h 2 o oxygen o 2. Cell membrane from an area of higher to an area of lower water potential other definitions of osmosis are as follows. Diffusion can occur in any mixture including one that includes a semipermeable membrane while osmosis always occurs across a semipermeable membrane.
