A botanist made a scientific investigation in a deserted place in the western United States. When he left, in order to find the place next time, he chose a special plant and marked it. However, after a few months, when he returned there, he found that the plant was missing! Careful scientists carefully observed the surrounding situation and found a shallow trace on the ground. Following this trace, he walked a long way and finally found the marked plant by a small lake. Plants can walk by themselves?
It turns out that this plant can grow in a fixed place where there is sufficient water. Once it is dry and short of water, its roots will leave the soil and the plant body will roll into a sphere. When the wind blows, it will move with the wind. When it encounters water, it will stop, insert its roots into the soil, obtain water and nutrients, and start its new life. Because this plant seems to be able to sense its surroundings and wake up from a deep sleep, it is called a wake-up tree.
There is also a plant called Tumbleweed in the desert. It can also roll its roots into a ball and roll with the wind when it is dry. From a distance, it looks like a small ball rolling rapidly. Where there is water, it will take root and grow again.
