what is osmosis?
the net movement of water from an area of higher water potential to an area of lower water potential across a partially permeable membrane
what is water potential?
the pressure created by water molecules → the ability of a solution to be able to carry out osmosis
(when solutes are dissolved in water, the water potential becomes negative)
what is the water potential of pure water?
0 kPa
what are the symbol and units for water potential?
symbol: ψ
units: kPa
what is a hypertonic solution?
a solution w/ a higher conc. of solutes than solvent (water)
what is an isotonic solution?
a solution w/ a similar conc. of solutes to solvent (water)
what is a hypotonic solution?
a solution w/ a lower conc. of solutes than solvent (water)
