water potential Flashcards
water potential
. free energy per mole of water
predicts which way water diffuses
water potential is based on what two factors
solute potential and pressure potential
solute potential
potential energy created by solute concentrations, water tendency to move toward hyper-tonic areas
pressure potential
potential energy created by pressure
Free energy of Water & water concentrations is based on
free water
what water is not free
Water that is H-bonded to solutes is not free
more free water means
more free energy = higher ψ
water moves from
Water moves from high free water areas to low free water areas
higher solute means
less free water
less water potential
solute potential of distilled water is
zero
solute potential is based on
-i
solute potential is neg or pos
negative
water flows toward more neg or pos
negative
negative pressure =
tension
positive pressure =
turgor pressure/osmotic pressure
