Plants travel in the following ways: animals, wind, water, catapults.
1. Travel by water.
Coconut: Spread by water, when the coconut is ripe, the coconut fruit falls into the sea and drifts away with the sea.
2. Rely on birds or other animals to travel.
Xanthella: The tip of the prickly hair has a barb, which can firmly hook the animal's body and is not easy to fall off.
3. Rely on the wind to travel and travel.
Dandelion: The achene of the Asteraceae plant dandelion, when ripe, the crown is quietly hairy, like a parachute, fluttering in the wind, spreading the seeds far away.
4. There are also methods of mechanical tourism.
Bauhinia: It relies on elasticity to disperse the seeds of the slag. When the ripe fruit of the bauhinia is touched lightly, the fruit will crack, and the elastic force of the peel will eject the seeds, and the seeds will be bounced far away.

There are two ways to spread plant seeds: one is with the help of external forces, such as wind, water, animals and humans; The second is to rely on the power generated by itself. In order to reproduce their offspring, plants can be said to be "eight immortals crossing the sea, each showing their magical powers".
The method of the mothers in the text is that the dandelion mother spreads the seeds with the wind. Mother Xanthus spreads its seeds by hanging on to the animal's fur with the help of small spines. The pea mother makes the pea bounce away, that is, spreads the seeds by stretching the force.
1. "Plant Mother Has a Way" is a poem, which uses anthropomorphic techniques to vividly express scientific knowledge in the form of rhymes, and the language is catchy, which is a popular science work that you never get tired of reading. This text vividly describes the method of dispersing seeds by three plant mothers, dandelions, xanthus, and peas.
2. The text "Mother Plant Has a Way" explores the mystery of seed dispersal by mother plant, in fact, mother plant not only spreads seeds, but some plants also prey on insects. There are many kinds of plants in nature, and the ways in which plants disperse seeds are also varied and strange.
Text: Mother Plant has the following methods:
1. The mother coconut tree prepares the armor and lets her children wear it. As long as it floats on the beach, the coconut can grow tender green seedlings;
2. There is a good way to spray melon mother, it sprays seeds from the top, as long as it shoots around, it can take root;
3. The grape mother has more methods, it allows the child to wear bright clothes, and it takes root and sprouts with the dung.
There are many, many more secrets of the plant world, and careful children can get it.

Haha, the idea is quite novel. However, I know that there is one plant in nature that travels with the help of aerial flight – and that is the dandelion, whose flowers are blown away by the wind and fall in every area where the wind passes, enabling a space trip.

One is with the help of external forces, such as wind, water, animals and humans; The second is to rely on the power generated by itself.
For example, the seeds of poplars and willows, which have soft fluff and fly freely in the spring breeze of May, to distant places.
The seeds of wild oats, which are able to "crawl" into the soil on their own. Wild oat seeds have a long mango on the shell, which will rotate or straighten with the change of air humidity, and the seeds will move forward little by little in the continuous stretching and bending of the long mango, and once they hit the gap, they will burrow into it, and the next year it will take root and sprout.
A brief introduction to Yanagi.
It is a general term for the salix genus, which has more than 400 species and is commonly found in the cold and temperate moist soils of the northern hemisphere.
Willow plants are very easy to cross, and natural or artificial hybrids are common.
Large deciduous tree, willow branches slender, soft and drooping, like wetlands, up to 20 30 meters high, 50 60 cm in diameter, rapid growth; The bark tissue is thick and longitudinally cracked, and the center of the old trunk is rotten and hollow.

1. Spread by the wind: Some plant seeds such as poplars and reeds can be blown to other places by the wind, and tumbleweeds can be blown to other places by the wind.
2. Spread through animal hair: Some plant fruits have thorns, which can stick to animal hair and be taken elsewhere.
3. Spread through birds: Birds eat animal fruits and then pull their droppings to other places, where the seeds grow.
4. Spread through flowing water: Some plant fruits can float on the surface of the water and be washed away by the flowing water to reproduce. Like a coconut carried by the sea to another land; Another example is a lot of aquatic floating plants, water chestnuts, duckweed drifting with the water.

Answer: Hello, plant travel generally has to be spread by the wind, such as dandelion and other plants, the seeds have parachute-like fluff, under the blowing of the wind, the seeds will fall to other places, and then they will take root. In addition, there are also some plants that cling to animals or travel to other places after swallowing and excreting.
Dear, I hope you can be satisfied with my reply, and I look forward to your praise Thank you! Have fun every day!

The methods of plant travel are:
1. The help of the wind. When the wind blows, dandelions, poplars, catkins, and their seeds go on a trip together!
2. Human help. In modern society, the sowing of plants is most inseparable from people, such as potatoes, coffee, and pumpkins, all of which come from distant countries and come to all parts of the world through people.
3. Help from animals. The animal eats the seeds of the plant in its stomach, and before it can be completely digested and excreted, it comes to a new world.
4. The plant's own instinct. Some plant seeds will find soil on their own and grow on their own. They have a strong vitality, hydroponics and soil cultivation can be, such as pothos.
5. Animal fur. When the critter passes by some thorny plants like Xanthus, the seeds stick to its fur and begin its journey.
6. Natural disasters. When encountering natural disasters such as flash floods or tsunamis, the water will wash away some of the vegetation on both sides of the river, and the water will rush to **then ** is the end of the plant's journey.
