Question

What is the difference between osmosis and diffusion​

Answer 1

Answer:

Osmosis is the movement of molecules from a region of lower concentration to a region of higher concentration through a semi-permeable membrane

WHILST

Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration until the molecules are evenly distributed

Answer 2

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.
