What is Osmosis?????
Answers
Osmosis is the spontaneous net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides.
- movement of a solvent (such as water) through a semipermeable membrane (as of a living cell) into a solution of higher solute concentration that tends to equalize the concentrations of solute on the two sides of the membrane.
Osmosis is the diffusion of water across a partially permeable membrane from a dilute solution (high concentration of water) to a concentrated solution (low concentration of water). In the diagram, the concentration of sugar is initially higher on the right side of the membrane.
The molecules that move in osmosis are liquid, and their movement is slower than in diffusion. Osmosis is a random and unidirectional biophysical process. Osmosis can take place between the two similar solution constituents. Osmotic pressure is the driving force that promotes osmosis.
- Osmosis is the net movement of water across a selectively permeable membrane driven by a difference in solute concentrations on the two sides of the membrane. A selectively permiable membrane is one that allows unrestricted passage of water, but not solute molecules or ions.
