Hello. Thanks for tuning in. My name is Mia, and today, I'm going to be debunking a common
science misconception that plants can't move. But first, let's go see what Alejandra is up to.
Where should I put my plant? Oh my God,
this is a great spot! Surely, it will grow straight up, right?
Pause. Alejandra believes her plant won't move in a different direction while it grows.
However, plants CAN actually move towards the light. The scientific term for it is phototropism.
[disco music] Phototropism is the growth of an organism in response to a light stimulus.
This can be the Sun, or it could be an artificial form of light. Either way,
light is vital for plants to prosper. So because Alejandra is growing her plant
in a dark place, as it grows it will bend towards the nearest light source.
Oh, look. Here comes Miles to help her out.
Hey Alejandra, are you sure you want to put your plant there? Yes, I'm positive. Why?
Because it's going to end up going towards the sun. No,
it's not. Plants can't move. They grow straight up.
Of course, they move. Look at that plan over there.
It's called phototropism.
Now we know that plants can move. They move towards the light,
just like the oak tree that Miles showed us, for example.
The tree was planted in a dark location and since then has grooved its way towards the Sun.
Your turn! Grab a plant and place it in a dark location. Have a concentrated light
source available to your plant, and watch as your plant dances towards the light.
