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.

How does osmosis differ from diffusion quizlet?

What is the difference between osmosis and diffusion? Osmosis is the movement of water molecules through the cell. Diffusion is the movement of molecules, such as oxygen, in and out of a cell. The process by which water molecules are able to diffuse through the cell membrane.

What are three differences between osmosis and diffusion?

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.
