Key concepts
3 concepts
- 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.
