Question

different between diffusion and osmosis​

Answer 1

Explanation:

In diffusion, particles move from an area of higher concentration to one of lower concentration until equilibrium is reached.

In osmosis, a semipermeable membrane is present, so only the solvent molecules are free to move to equalize concentration.

Answer 2

Definitions:

Diffusion: Diffusion is the movement of particles from an area of higher concentration  to lower concentration. The overall effect is to equalize concentration throughout the  medium.

Examples of Diffusion: Examples of diffusion include perfume filling a whole room and  the movement of small molecules across a cell membrane. One of the simplest  demonstrations of diffusion is adding a drop of food coloring to water. Although other  transport processes do occur, diffusion is the key player.

Osmosis: Osmosis is the movement of solvent particles across a semipermeable  membrane from a dilute solution into a concentrated solution. The solvent moves to  dilute the concentrated solution and equalize the concentration on both sides of the membrane.

Examples of Osmosis: Examples of osmosis include red blood cells swelling up when  exposed to fresh water and plant root hairs taking up water. To see an easy  demonstration of osmosis, soak gummy candies in water. The gel of the candies acts as a semipermeable membrane.

Differences:

In diffusion, particles move from an area of higher concentration to one of lower concentration until equilibrium is reached.

In osmosis, a semipermeable membrane is present, so only the solvent molecules are free to move to equalize concentration.
