Osmosis is the the diffusion of water or any soluble liquid across a semipermeable membrane such as the outer membrane of a cell.

When water moves out of the cell faster then the intake of water, the cell will shrink. This is a hypertonic solution. When the intake is greater than the output, the cell will grow. This is a hypotonic solution. When a balance is achieved, water moving equally in and out of the cell, an isotonic solution is created.

Dialysis is when the kidney allows only certain things to DIFFUSE through it. For example, a Biology class put an egg in a vinegar solution. This causes the egg to grow because the vinegar was at a higher concentration then the inside of the egg and biology states that it will flow from a high concentration to low concentration. When that same egg is placed in water, the vinegar flows out of the egg because the water was a lower solution of vinegar than the egg.

So all of this comes down to the fact that in both osmosis and dialysis, something is being diffused through the cell's semipermeable membrane. If you need a clearer explanation, ask you school's biology teacher(s).

Related Questions

Can osmosis and diffusion can both occur at the same time through a dialysis membrane?

Yes, osmosis and diffusion can occur simultaneously through a dialysis membrane. Osmosis involves the movement of water molecules across a semi-permeable membrane, while diffusion involves the movement of solute molecules. Both processes can occur independently of each other through a dialysis membrane when there is a concentration gradient present.


What is the opposite of osmosis?

The opposite of osmosis is dialysis, which involves removing waste and excess substances from the blood by passing it through a membrane. In dialysis, solutes move from an area of high concentration to low concentration rather than water moving through a semi-permeable membrane like in osmosis.


Is dialysis osmosis or diffusion?

Dialysis is the separation of particles in a liquid on the basis of differences in their ability to pass through a membrane. As a semi permeable membrane is involved, so it is an osmosis.


Are diffusion and osmosis passive or active transports?

Diffusion and osmosis are passive and do not require energy.


What is a synonym for osmosis?

Do cells have to work to make osmosis happen?

No, osmosis is a type of diffusion. Diffusion never requires work. Osmosis occurs when water seeks equilibrium. The water will naturally try to have the same amount of solvents in it without work from the cell. You can do osmosis experiments using a dialysis bag. Put solvent (such as sugar) in the bag with some water. Then put the bag in a cup of water. Watch what happens :)

What involves the movement of solutes across a selectively permeable membrane by the process of difussion?

Osmosis involves the movement of solutes across a selectively permeable membrane by the process of diffusion. In osmosis, water molecules move across the membrane from an area of low solute concentration to an area of high solute concentration in order to equalize the concentration on both sides of the membrane.
