Osmosis is when a substance crosses a semipermeable membrane in order to balance the concentrations of another substance. In biology, this is usually when a solvent such as water flows into or out of a cell depending on the concentration of a solute such as salt.
osmosis, the spontaneous passage or diffusion of water or other solvents through a semipermeable membrane (one that blocks the passage of dissolved substances—i.e., solutes). The process, important in biology, was first thoroughly studied in 1877 by a German plant physiologist, Wilhelm Pfeffer.
In biology, osmosis is the net movement of water molecules through the membrane from an area of higher water potential to an area of lower water potential.
Osmosis is the transfer of solvent from a region of lower concentration to a region of higher concentration. Explore more about the definition of osmosis and osmotic pressure.
Osmosis is the movement of a solvent across a semipermeable membrane toward a higher concentration of solute. In biological systems, the solvent is typically water, but osmosis can occur in other liquids, supercritical liquids, and even gases. [11] [12]
The meaning of OSMOSIS is 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. How to use osmosis in a sentence.
Osmosis is the diffusion of water molecules across a selectively permeable membrane from an area of higher concentration to an area of lower concentration. Water moves into and out of cells by osmosis.
Definition of Osmosis. Osmosis is the spontaneous movement of solvent molecules, typically water, through a selectively permeable membrane from a region of lower solute concentration to a region of higher solute concentration, aiming to equalize solute concentrations on both sides.
Revise how gases and liquids transport into and out of both animal and plant cells occurs through diffusion, osmosis and active transport.
In physiology, osmosis (Greek for push) is the net movement of water across a semipermeable membrane (see Figure. Osmosis). [1] [2] Across this membrane, water will tend to move from an area of high concentration to an area of low concentration.
