Understanding What Plant Transpiration Is
Plant transpiration is the process where plants release water vapor through tiny openings in their leaves. It helps them stay cool and move nutrients.
How Transpiration Works
Water travels from the roots to the leaves. When it evaporates into the air, more water is pulled upward through the plant, keeping it hydrated.
Where Transpiration Happens
Most transpiration occurs through stomata—small pores on the underside of leaves that open and close to control water loss and gas exchange.
Why Plants Need Transpiration
Cooling: Evaporation helps prevent overheating.
Nutrient transport: Water movement carries minerals from roots to leaves.
Water flow: Keeps cells firm and supports plant structure.
Factors That Affect Transpiration
Temperature, sunlight, humidity, wind, and soil moisture all change how fast plants transpire.
Examples of Transpiring Plants
All plants transpire—trees, grasses, flowers, crops, and even houseplants release water vapor throughout the day.
The Simple Takeaway
Plant transpiration is how plants release water vapor through their leaves. It cools them down and helps move water and nutrients throughout the plant.
