Question

How will you differentiate between osmosis and diffusion?​

Answer 1

Answer:

One big difference between osmosis and diffusion is that both solvent and solute particles are free to move in diffusion, but in osmosis, only the solvent molecules (water molecules) cross the membrane.

Explanation:

Answer 2

Answer :-

★ Osmosis -

Osmosis can be defined as the movement of water (solvent) from a region of higher concentration to a region of lower concentration through a semi-permeable membrane.

★ Diffusion -

Diffusion can he described as the movement of molecules (solid, liquid or gases) from a region of higher concentration to the region of lower concentration (does not require a semi-permeable membrane).

The important points of distinction/difference between osmosis and diffusion are as follows :-

Difference 1 :

• Osmosis involves the diffusion of solvent molecules (water molecules) only.

• Diffusion involves the movement of both solute and solvent molecules.

Difference 2 :

• Osmosis occurs from lower solute concentration to higher solute concentration.

• Diffusion occurs from higher solute concentration to lower solute concentration.

Difference 3 :

• The presence of a semi-permeable membrane is essential for osmosis.

• The presence of a semi-permeable is not required for diffusion.

Difference 4 :

• Osmosis is limited to solutions only.

• Diffusion is common to both solutions and gases.

Difference 5 :

• Osmosis can be stopped or reversed by applying pressure on the higher concentration side.

• Diffusion can not be reversed (by any means).
