People sweat to cool off and plants do, too. Well, its not exactly sweat, its called transpiration.
And instead of water dripping off the leaves like sweat on your skin, the water comes out from leaves in gas form as water vapor.
When its really hot outside, plants need to transpire more water to stay cool.
So, how many gallons can a tree lose because of transpiration on a hot summer day?
Scientist have shown that a large willow tree can transpire
5,000 gallons in one day!
