There are many kinds of plants in nature, and their seeds travel in different ways. One is to rely on external forces, such as wind, water, animals and human beings; the other is to rely on the power generated by oneself.

The seeds of many plants can travel thousands or dozens of kilometers away in various unique ways, and some can even "roam around the world"!

1· ?The seeds of plants such as soybeans, mung beans, rapeseed, sesame, etc. have the ability to "eject". After the fruit matures, the pods containing the seeds will suddenly twist and explode, ejecting the seeds to dozens of centimeters or even meters. outside. According to the information currently available, the "champion" of projectiles in the plant world may be a mignonette that grows in the Americas, with a range of up to 14 meters.

2· ?In northern Africa and southern Europe, there is an interesting plant called Penguin. When its fruit matures, the juice containing the seeds is like the air in a balloon, exerting strong pressure on the peel. With just a light touch, the mucus and seeds of the fruit will erupt together, and can shoot up to 6 meters away. , so the locals call it "Iron Pao Gua".

3· ?There are many seeds that travel in water. Take the lotus for example. Its fruit pod is like a small boat, floating lightly on the water, drifting around, carrying seeds to distant places. When the lotus pod rots, the seeds sink to the bottom of the water. The next spring, a new lotus grew again. There are also water lilies, whose spongy berries have a very peculiar structure. There are many seeds inside the berries. Each seed has an air-filled sac wrapped around it, just like a lifebuoy. When drifting for long distances, the air in the sac slows down. It slowly disappears and the seeds sink to the bottom of the water.

4· ?Cherry, wild grape, wild ginseng: The seeds are eaten by birds or other animals. Since they cannot be digested

they are excreted with feces and spread in all directions. .
