Osmosis definitions Flashcards

The diffusion of water across a semipermeable membrane from low to high solute concentration.

A barrier allowing certain small molecules to pass while blocking others like ions or large molecules.

A substance, typically water, that dissolves solutes and moves across membranes in osmosis.

Particles dissolved in a solvent, affecting the direction of osmosis based on concentration.

The difference in solute concentration across a membrane, driving osmosis.

The force required to stop solvent flow through a semipermeable membrane.

The relative concentration of solutes in solutions, determining solvent flow direction.

A solution with lower solute concentration and osmotic pressure compared to another.

A solution with equal solute concentration and osmotic pressure as another.

A solution with higher solute concentration and osmotic pressure compared to another.

The state where solute concentrations are equal on both sides of a membrane, halting net solvent flow.

The swelling and bursting of a cell due to excessive water intake in a hypotonic environment.

The shrinking and dehydration of a cell due to water loss in a hypertonic environment.

Fluids administered into veins, which must be isotonic to bodily fluids to prevent cell damage.

A cell affected by osmotic conditions, swelling in hypotonic and shrinking in hypertonic environments.
