Why dandelions become bald?

Why dandelions become bald? Did you think sometime of it? Also it is thought up so interestingly. For example, why when the rose or a lily fades, she loses the petals, but they just fall down also everything, and at dandelions on the contrary, petals become lungs as a fuzz and they fly to the sky. Probably dandelions not simple colors. and heavenly. friends!!! They seek to fly to the sky when die.

I was the involuntary witness of it and these thoughts have come to my mind after what was seen.
