Diffusion and Osmosis Basics

Front

Diffusion

Back

Movement of particles from high to low concentration

Front

Osmosis

Back

Movement of water, from low concentration to high concentration through a semi-permeable membrane

Front

Concentration Gradient

Back

Difference in concentration across space

Front

Semi-permeable Membrane

Back

Allows certain molecules to pass through

Front

Equilibrium

Back

Equal concentration on both sides

Front

Solvent

Back

Substance that dissolves a solute

Front

Solute

Back

Substance dissolved in a solvent

Front

Hypertonic Solution

Back

Higher solute concentration outside the cell

Front

Hypotonic Solution

Back

Lower solute concentration outside the cell

Front

Isotonic Solution

Back

Equal solute concentration inside and outside the cell
