Transcript

A yellow dandelion is growing in the grass. How does it become a fluffy white ball?

After the yellow flower is done blooming, its tiny flower parts make seeds. Each seed grows a little white parachute.

The white parachutes open into a round, fluffy puff. They help the seeds catch the wind.

A breeze can lift the seeds and carry them far away. If a seed lands in good soil, it can grow a new dandelion.

So dandelions turn fluffy to help their seeds travel. The fluff is like a tiny parachute for each seed.

For grown-ups: the science

Dandelions turn fluffy because their seeds grow white parachutes that let the wind carry them away.

A dandelion flower head contains many small flowers. After pollination and seed development, each seed forms a feathery structure called a pappus. The pappus increases air resistance, allowing wind to disperse the seeds.
