Question

difference between diffusion and osmosis​

Answer 1

Answer:

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. Hydrostatic pressure and turgor pressure oppose osmosis.

Diffusion does not depend on solute potential, pressure potential, or water potential. Osmosis depends on solute potential.

Diffusion mainly depends on the presence of other particles. Osmosis mainly depends on the number of solute particles dissolved in the solvent.

Diffusion is a passive process. Osmosis is a passive process.

The movement in diffusion is to equalize concentration (energy) throughout the system. The movement in osmosis seeks to equalize solvent concentration, although it does not achieve this.

Answer 2

Diffusion:

1. It occurs in any medium.

2. Diffusing molecules may be solid, liquid or

gaseous solutes.

3. Semi-permeable membrane is not required.

Osmosis:

1. It occurs in liquid medium only.

2. It involves movement of solvent molecules

only.

3. Semi-permeable membrane is required
