|
osmotic pressure
|
the amount of pressure required exactly to oppose the osmosis/osmotic flow
|
|
|
osmosis
|
passive diffusion of water
|
|
|
OsM
|
osmoles per liter
|
|
|
1 osmole =
|
1 mole of solute particles
|
|
|
1 OsM (osmolar) =
|
1 mole solute particles/liter
|
|
|
osmolarity
|
the ability of an object to induce water to cross a membrane
|
|
|
isosmotic
|
amount of solute is the same both inside and outside of the cell - there is no net movement
|
|
|
hyposmotic
|
there is less particles outside the object than in the environment there fore the object swells up
|
|
|
hyperosmotic
|
there are more particles outside of the object therefore water leaves the object and the object shivels
|
|
|
tonicity
|
the effect of solute concentration on cell tone/volume
|
|
|
isotonic
|
the object and environment are exactly the same and there is no net flux occuring
|
|
|
hypertonic
|
the cell has too many solutes so water escapes and the cell shrinks
|
|
|
hypotonic
|
the cell has too little solute so water enters the cell and the cell swells
|
