    Information Osmosis is one of the four methods of moving particles across membranes along with simple diffusion‚ facilitated diffusion‚ and active transport. Water is able to move in and out of most cells freely. Sometimes the number of water molecules moving in and out is the same and there is no net movement‚ but at other times the molecular movement from one direction exceeds the movement from other direction and creates a net movement. This net movement is called osmosis. Osmosis is due to differences
