Notes on Tonicity

TermDefinition
Diffusion The movement of molecules of substances from an area of higher concentration to an area of lesser concentration to reach equilibrium
Passive transport or simple diffusion The movement of molecules from an area of higher to lower concentration to reach equilibrium without expanderes of energy.
Facilitated diffusion The transport of substances across a membrane by means of a carrier molecule
Active transport When solute must pass through the cell membrane past its concentration gradient.
Osmosis The movement of molecules of a solvent through a semi permeable membrane from an area of higher to lesser concentration to reach equilibrium
Concentration gradient The direction of the movement of molecules of substances.
Tonicity Movement of molecules of a substance is inside and out of the cell
Isotonic When solvent can go inside and outside of the cell because there is an equal amount of solvent and solute outside and inside the cell
Hypertonic When solvent can only go outside of the cell because there is a greater amount of solvent inside the cell. There is a smaller amount of solute outside of the cell. As a result the cell shrink
Hypotonic When solvent only inside of the cell because there's a greater amount of solvent outside. There is a lesser amount of solute inside the cell. As a result the cell will swell.
