• left to right

• up and down

Solution with a higher solute concentration…

• Hypertonic

• Hypotonic

• Isotonic

Solution with a lower solute concentration…

• Hypertonic

• Hypotonic

• Isotonic

Solution with a lower free water concentration…

• Hypertonic

• Hypotonic

• Isotonic

Extracellular solution is 0.5M and the cell is 1.0M – which direction will water flow?

• Into cell towards hypertonic solution

• Into cell towards hypotonic solution

• Out of cell toward hypertonic solution

• Out of cell toward hypotonic solution

Solution with a higher free water concentration…

• Hypertonic

• Hypotonic

• Isotonic

If the intracellular concentration is 1.0 M and extracellular concentration is 0.4M. Which direction does water flow?

• Both in and out (equilibrium)

• Into the cell

• Out of the cell

If solution A has -4.0 MPa and solution B has -2.0 MPa, which direction will   water flow?

• Out of solution A

• Out of solution B

If extracellular solution is isotonic, which direction will water move?

• Into cell

• Out of cell

• Both into and out of cell

• No water movement

The higher the solute concentration…

• the higher the water potential

• the lower the water potential
