Question

How is diffusion different from osmosis? for class 9​

Answer 1

Answer:

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.
