concentrated area to a low concentrated area. Water is one molecule that can diffuse freely in a cell. Other molecules need assistance through the cell membrane through a process called facilitated diffusion. Osmosis moves from an area of low concentration to high concentration. In osmosis water moves in the opposite way. Water flow is determined by the concentration‚ not the nature of the solute. There are a couple of things to consider for diffusion to work. The size of the cell‚ permeability

Osmosis is the spontaneous net movement of solvent molecules through a partially permeable membrane into a region of higher solute concentration‚ in the direction that tends to equalize the solute concentrations on the two sides.[1][2][3] It may also be used to describe a physical process in which any solvent moves‚ without input of energy‚[4] across a semipermeable membrane (permeable to the solvent‚ but not the solute) separating two solutions of different concentrations.[5] Although osmosis does

http://thegrabup.com/?p=811 Significance Of Osmosis (700-1200) Osmosis is a process of movement of solvent through a semi permeable membrane from an area of high water concentration to an area of low water concentration to equalize the concentration of solute to both side of the membrane. . Water is sometimes called "the perfect solvent‚" and living tissue (for example‚ a human being’s cell walls) is the best example of a semipermeable membrane. Osmosis process as demonstrated below shows that when
