Water moves from areas of higher water potential to areas of lower water potential, aiming to minimize its potential energy. Think of water as a downhill skier 🎿 always looking for the fastest route down the hill!

• Water Potential: A measure that predicts the direction in which water molecules will move.
• Potential Energy: The stored energy that has the ability to do work.
• kPa: Kilopascal, a unit of pressure used to express water potential in cells.

Just like how your dog 🐶 runs from the kitchen to the living room at the whiff of a treat, water molecules are always in motion. They move from areas of high water potential to low water potential. Why? Because things in nature love to minimize their potential energy!

Imagine you're at the top of a slide at a water park 🌊. Naturally, you're going to slide down, not climb up! This slide is the metaphorical hill for water molecules. The "potential energy" you had at the top is minimized as you slide down to a lower point. Nature's lazy but efficient that way!

Cells have some quirky values for water potential. The highest it goes is 0kPa. Anything else is negative, like a leaf cell might have -200kPa.
