NASA Kids Science News segment explaining how plants grow in space.
Hi, I'm Cory with science news that you can use.
00:00:00
Why do plants grow up?
00:00:06
Is it because they go towards light?
00:00:08
That's true, but plants also use gravity to know what is up and what is down.
00:00:10
On Earth, plants can sense the direction that gravity is pulling them, and they grow in the opposite direction.
00:00:14
Oh, and what happens in space when there is no up or down?
00:00:20
Experiments in space have shown that in less gravity, plants still grow towards light.
00:00:23
NASA scientists are planning more experiments in space to better understand why plants still grow towards light,
00:00:28
even though there is no gravity present.
00:00:34
NASA knows plants will be important in space because they will consume the carbon dioxide we exhale,
00:00:36
give us oxygen and food, and purify our water.

Until next time, I'm Cory with cool science news that you can use.
