|
Define diffusion |
is the movement of molecules from a higher to a lower concentration until equilibrium is achieved |
|
osmosis |
is the diffusion of water across the plasma membrane of a cell |
|
Tonicity |
is the relative concentration of solute and therfore also of solvent outside the cell compared to the inside of the cell
|
|
Isotonic |

|
Hypertonic |
has a higher solute concentration then the cell |
|
Hyoptonic |
