3.3 - Osmosis and Osmolarity Flashcards
1
Q
Hypertonic Solution
A
Water moves out, cell shrivels
2
Q
Aquaporins
A
Channel for water entry into cells
3
Q
Concentration Gradient
A
Difference in solute concentration
4
Q
Example: Situation: Cell in Hypertonic Solution
A
Cell shrivels due to water loss
5
Q
Example: Situation: Cell in Hypotonic Solution
A
Result: Cell swells due to water gain
6
Q
Hypotonic Solution
A
Water moves in, cell swells
7
Q
Isotonic Solution
A
Even water movement, normal cell volume
8
Q
Osmolarity
A
Solute particles per liter in solution
9
Q
Osmolarity Equilibrium
A
Equal osmolarity inside and outside cell
10
Q
Osmosis
A
Diffusion of water
11
Q
Solute Effect
A
Water movement due to added solute
