Question

What is the difference between osmosis and diffusion?

Osmosis is the movement of water across a membrane; diffusion is the movement of molecules from a higher to a lower concentration, with or without the presence of a membrane.


Diffusion is the movement of water across a membrane; Osmosis is the movement of molecules from a higher to a lower concentration, with or without the presence of a membrane.


Osmosis is the movement of molecules from an area of low concentration to an area of high concentration; diffusion is the opposite.


Diffusion is the movement of molecules from an area of low concentration to an area of high concentration; osmosis is the opposite.

Answer 1

Osmosis is the movement of water across a membrane; diffusion is the movement of molecules from a higher to a lower concentration, with or without the presence of a membrane.

Explanation: i took the test

Answer 2

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.
