Seed Dispersed by Wind/ Sepals on a Flower/ Plant with Tap Root System: Backyard 5/18/11

This is an example of a seed that is dispersed by wind. The seeds of this dandelion are designed so that wind can carry the seeds over long distances, where they can eventually develop into new dandelions. The sepals can be seen at the base of this flower. They surround the reproductive parts of the flower and protect the new growing shoot. Dandelions also have a tap root system. This means that it has an enlarged root that grows vertically, and other roots grow horizontally from its center.
