Question

Difference between diffusion and osmosis

Answer 1

One big difference between osmosis and diffusion is that both solvent and solute particles are free to move in diffusion, but when we talk about osmosis, only the solvent molecules (water molecules) cross the membrane. ... When people discuss osmosisin biology, it always refers to the movement of water

Answer 2

DIFFUSION:Some substance such as carbon dioxide , oxygen , water etc.can move across the plasma membrane through a process called diffusion.

OSMOSIS: Water also follows the law of diffusion .The spontaneous movement of water molecules through a selective permeable membrane is called osmosis.
