- The potential energy of water is called water potential.
- Water potential is the tendency of water to move from one area to another. due to osmosis, gravity, mechanical pressure, and surface tension.
- For example, water movement within plants, animals, and soil.
- Water potential is denoted by ψ.
- In negative water potential, the flow of water is not restricted, i.e. water will move from an area of higher water potential to an area that is lower potential.

Explanation:
Water potential is the potential energy of water per unit volume relative to pure water in reference conditions. Water potential quantifies the tendency of water to move from one area to another due to osmosis, gravity, mechanical pressure and matrix effects such as capillary action
