Osmosis Flashcards
1
Q
Osmosis
What is it?
A
- movement of water molecule
- high water potential to lower water potential
- through partially permeable membrane
- down water potential gradient
2
Q
high water
A
water has greater potential energy
3
Q
low water
A
lower water potential
4
Q
more concentrated solution
A
more negative the water potential
5
Q
Hypertonic
A
- solution has higher solute conc. than cell
- if water potential of external solution is lower than inside cell
- water flows out
6
Q
Hypotonic
A
- solution of lower solute conc. than cell
- if water potential of external solution is higher than cell
- water flows into cell
7
Q
Isotonic
A
- solution of equal conc. to the cell
- molecules still move in and out
- no net movement
