Difference between osmosis and diffusion

However, if you add sugar or salt to the blood sample, water will leave the red blood cells and cause them to shrink and pucker. Diffusion and osmosis are passive processes, meaning they don't need energy to occur. Both are spontaneous processes. Diffusion depends on the random movement of particles or molecules. It increases with a rise in temperature because heat increases the random movement of molecules. In osmosis, water freely moves across a membrane from an area of low solute concentration, or hypotonic solution, to one of high solute concentration, or hypertonic solution.

When the solute concentration is equal on both sides of the membrane, the solution is said to be "isotonic. Diffusion across a membrane depends on the size and electric charge of molecules. Smaller molecules diffuse faster than larger molecules. Charged molecules do not diffuse across animal or plant cell membranes; they need to enter or leave cells by other mechanisms, because cell membranes are made up of hydrophobic lipids and repel charged molecules similar to how oil repels vinegar.

Osmosis is the flow of water molecules and depends on the particle concentration — not the type of molecule on either side of the membrane. Diffusion occurs with or without a membrane between two areas of different concentrations of molecules. However, osmosis only occurs across a semipermeable membrane, a membrane that prevents many particles or molecules to freely travel between the two sides, while allowing water to pass through. In nature, osmosis is essential for many biological processes that depend on the movement of water, such as cell shape or pressure.

How Does Diffusion Work? How to Calculate Isotonicity. Osmosis and diffusion are related processes that display similarities:. Here's how they are different:.

Updated February 06, Diffusion Versus Osmosis Diffusion Osmosis Any type of substance moves from an area of highest energy or concentration to a region of lowest energy or concentration.

Only water or another solvent moves from a region of high energy or concentration to a region of lower energy or concentration. Diffusion can occur in any medium, whether it is liquid, solid, or gas. Osmosis occurs only in a liquid medium. Diffusion does not require a semipermeable membrane. Osmosis requires a semipermeable membrane. The concentration of the diffusion substance equalizes to fill the available space.

The concentration of the solvent does not become equal on both sides of the membrane. Hydrostatic pressure and turgor pressure do not normally apply to diffusion.
