What is auxin?

Plants have a special helper called auxin that helps them grow taller and stronger.

Imagine you're playing on a swing. When you push yourself forward, you go higher, and when you stop pushing, you still keep moving forward for a little while. Auxin works kind of like that push. It's a message inside the plant that tells parts of it to grow more in certain directions.

When a plant is growing, auxin moves from where it’s made, usually near the tip of a stem or root, to other parts of the plant. If there's more auxin on one side of a stem, that side grows faster than the other. This makes the plant bend toward light, just like how you might tilt your head when you see something interesting.

It's like having a friend who always helps you reach for the top shelf, even if they're not as tall as you are! Auxin is that helpful friend inside every plant.
