Dandelion is weirder than you think!
When the wind blows on a dandelion, some of its beautiful seeds travel north, while others go east, south, west. And they fly in any other direction. In this regard, it is interesting to know that based on research conducted on November 20 this year in the Fluid Dynamics Department of the American Physical Society in Indianapolis, researchers have shown that each Dandelion seed is programmed in such a way that only if the wind blows in a certain direction, take flight and resist the wind in other directions!
"Jena Shields" (Jena Shields), a biophysicist at Cornell University, admits that Dandelion seeds, depending on the position they are on the cap of the plant, are relatively They are sensitive to different wind directions. Seeds that are in the direction of the breeze are easily released, but other seeds remain ten or hundreds of times stronger on the Dandelion cap until the wind changes direction.
Different Dandelion seeds are sensitive to the blowing of the wind, either naturally or by a curious child, the same problem is scattered. Wider and better distribution of these plants helps.
Playing with dandelions and understanding its wonder
So, according to what was raised, Gina Shields and her colleagues began to investigate and test this beautiful plant. They did, to take what was a hypothesis to the proof plant.Dandelion seeds are sensitive to different wind directions depending on the position they are on the cap of the plant. This issue can also be a factor for spreading and expanding these plants more successfully than others!
In this regard, Shields measured the force required to separate Dandelion seeds by attaching a fine wire to the bristle end and pulling the seeds from the cap at different angles. During this experiment, the moment of separation of the seeds was imitated either by natural wind blowing or by a curious child. In this experiment, it was found that some seeds are more sensitive to winds from certain directions than others, which helps prevent all seeds from spreading equally. So this study may explain why dandelions and similar plants are better at propagating than other plants. Of course, it should be noted that a strong wind can certainly blow all the seeds in one direction.
