Osmosis vs. Plasmolysis

Published:

Osmosisnoun

The net movement of solvent molecules, usually water, from a region of lower solute concentration to a region of higher solute concentration through a partially permeable membrane.

Plasmolysisnoun

(biology) the shrinking of protoplasm away from the cell wall of a plant or bacterium due to water loss

Osmosisnoun

Picking up knowledge accidentally, without actually seeking that particular knowledge.

‘I was reading about chickens, and I guess I learned about hawks through osmosis.’;

Plasmolysis

Plasmolysis is the process in which cells lose water in a hypertonic solution. The reverse process, deplasmolysis or cytolysis, can occur if the cell is in a hypotonic solution resulting in a lower external osmotic pressure and a net flow of water into the cell.

Osmosisnoun

The tendency in fluids to mix, or become equably diffused, when in contact. It was first observed between fluids of differing densities, and as taking place through a membrane or an intervening porous structure. An older term for the phenomenon was Osmose.

Osmosisnoun

diffusion of molecules through a semipermeable membrane from a place of higher concentration to a place of lower concentration until the concentration on both sides is equal

Osmosis

Osmosis (, US also ) is the spontaneous net movement or diffusion of solvent molecules through a selectively permeable membrane from a region of high water potential (region of lower solute concentration) to a region of low water potential (region of higher solute concentration), in the direction that tends to equalize the solute concentrations on the two sides. It may also be used to describe a physical process in which any solvent moves across a selectively permeable membrane (permeable to the solvent, but not the solute) separating two solutions of different concentrations.
