Define water potential in your own words. How does it help us understand the movement of water?

Water potential is the potential energy of water per unit area compared to pure water. It helps us predict the direction water will flow due to osmosis, pressure, gravity, and surface tension.

Explain the relationship between solute potential and the addition of solutes to a solution. How does adding more solutes affect the solute potential, and why?

As the number of solutes in a solution increases, the solute potential decreases (becomes more negative). This is because solutes bind to water molecules, reducing the water's freedom to move and thus lowering its potential energy.

Learning Objective

I can define water potential and its components.

1
Water potential, symbolized by Ψ (Psi) and associated with Poseidon's trident, measures the potential energy of water per unit area relative to pure water.
2
Water always flows from areas of high water potential to areas of low water potential.
3
Water potential (Ψ) is calculated by adding the solute potential and the pressure potential, which account for osmosis and physical pressure, respectively.
