Science Fact of the Week (11/8/17)

Did you know that plants BREATHE? It’s called TRANSPIRATION and it’s actually part of the water cycle.

Plants suck up water in the soil through their roots. The water travels all over the plant, and eventually leaves the plants through their leaves. But, by the time the water leaves it’s in the form of VAPOR or GAS!

If you put a plastic baggy over a plant’s leaf and leave it for a few hours, when you come back, you’ll be able to see water droplets in the bag. This is because the water vapor that the plant breathes out condenses back into liquid water droplets when they touch the inside of the baggy.
