What is meaning of ''Osmosis'' and ''Facilitated diffusion ?

Question

I want to understand of this two words .Somebody tell me ?

Answer 1

well osmosis is the inward or outwatrd movement of molecules across a semipermeable membrane and facilitated diffusion is the diffusion with the help of carrier molecules

Answer 2

Osmosis is the diffusion of water through a cell wall or membrane or any partially-permeable barrier from a solution of low solute concentration to a solution with high solute concentration, up a solute concentration gradient. It is a physical process in which a solvent moves, without input of energy, across a semi-permeable membrane (permeable to the solvent, but not the solute) separating two solutions of different concentrations. Osmosis releases energy, and can be made to do work, as when a growing tree-root splits a stone.

Facilitated diffusion (or facilitated transport) is a process of diffusion, a form of passive transport facilitated by transport proteins. The facilitated diffusion may occur either across biological membranes or through aqueous compartments of an organism.

Answer 3

Osmosis is the movement of water molecules from a higher water potential to a lower water potential down a water potential gradient across a permeable membrane; while facilitated diffusion is also the movement of molecules from higher concentration to a lower concentration down a concentration gradient; yet it involves in carrier proteins and channel protein (which is the integral membrane proteins ).
