Movement of particles or molecules from an area of high concentration to an area of low concentration. As the name suggests Reverse Osmosis is just the reverse process of Osmosis. There will be no ox. Osmosis is passive transport, meaning it does not require energy to be applied. Osmosis is the movement of solvent, such as water, through a barrier from a less concentrated solution into a more concentrated solution. Diffusion is when molecules or atoms move from an area of high concentration to an area of low concentration. In osmosis, the solvent moves from the hypotonic medium towards the hypertonic medium and reaches the end of the process when the two mediums are in concentration equilibrium. Three terms—hyerptonic, hypotonic, and isotonic—are used to describe whether a solution will cause water to move into or out of a cell: If a cell is placed in a hypertonic solution, there will be a net flow of water out of the cell, and the cell will lose volume. Dialysis is the separation (i.e. Dictionary entry overview: What does osmosis mean?
