OSMOSIS Flashcards
1
Q
Defintion of osmosis
A
the NET movement of water molecules from a high water potential to a low water potential through selectively permeable membrane
2
Q
what is water potential measured in
A
kilo pascals (kpa)
pure water has 0kpa
3
Q
what is solute potential
A
the greater the amount if solute the lower the water potential
because water and solute molecules bind togther meaning that there are less water molecules that are free to diffuse
4
Q
what is the pressure potential
A
the greater the pressure the higher the water potential
is always positive
