Osmosis Flashcards
1
Q
What is osmosis?
A
the passage of water from a region where it has a higher water potential to a region where it has lower water potential through a selectively permeable membrane
2
Q
solute
A
any substance dissolved in a solvent
3
Q
Water potential
A
- measured in pressure
- pressure created by molecules
- water has a water potential of zero
- addition of solute to pure water lowers its potential
4
Q
High water potential
A
water enters cell
swells and burst
5
Q
low water potential
A
leaves cell
shrinks
