D2.3 Water potential HL Flashcards
1
Q
Water Potential
A
Measure of potential energy of water, expressed in kPa
2
Q
Water Movement Direction
A
From higher to lower water potential
3
Q
Solute and Pressure Potential’s Effect
A
Solute decreases, pressure increases or decreases water potential
4
Q
Hypotonic Solution Effect
A
Water enters, increases turgor pressure
5
Q
Hypertonic Solution Effect
A
Water exits, reduces cell volume
6
Q
Water Potential Equation
A
Ψw = Ψs + Ψp
7
Q
Impact of Solute Particles
A
Attracts water, reduces free water molecules
