Definition
Glossary of "Life (9th ed.)" by Sadava et al. (2011)
- In osmosis, the tendency for a system (a cell or solution) to take up water from pure water through a differentially permeable membrane. Water flows toward the system with a more negative water potential. (Contrast with solute potential, pressure potential.
Glossary of "Botany (2nd ed)" by Moore et al. (1998)
- The potential energy of water to move down its concentration gradient; water potential is expressed in units of pressure instead of units of energy, because pressure is simpler to measure.
