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

Pressure potential = 0.2 MPa and solute potential = - 0.6 MPa…

• Water Potential = -0.8MPa

• Water Potential = -0.4 MPa

• Water Potential = 0.4 MPa

• Water Potential = 0.8 MPa

Solution with a higher free water concentration…

• Hypertonic

• Hypotonic

• Isotonic
