Tonicity and osmoregulation

Question 1

Isotonic solutions

Answer 1

No net movement of water, concentration of solutes is the same concentration as the water

Question 2

Hypertonic solutions

Answer 2

1. Lose water due to their extracellular surroundings
2. Solute levels higher outside of the cell
3. Water leaves the cell and cells shrivel and die

Question 3

Hypotonic solutions

Answer 3

1. Gain water
2. Solute levels lower outside of the cell
3. Water flows into the cell, cells swell and lyse (pop)

Question 4

Water potential

Answer 4

Physical property that predicts the direction water will flow

Question 5

Water will flow from areas of

Answer 5

1. High water potential to low water potential
2. Low solute to areas of high solute concentration
3. High pressure to low pressure
