Spring has come, and dandelion seeds are floating in the wind. Like a parachute, it landed on the land in the corner of the park. Dandelion seeds take root and sprout in the soil, and slowly grow into a small Xin Wei.
Dandelion Xiaowei looked around. The flowers in the park are really beautiful! Colorful and beautiful.
The gardener's uncle will weed, fertilize, water and prune those beautiful flowers every day; Every day, visitors in the park will stop to look at those beautiful flowers, and sometimes take pictures as a souvenir;
Every day, hardworking bees and beautiful flowers will fly to collect nectar and spread pollen for those beautiful flowers; Birds wander among those beautiful flowers every day, fascinated by their beauty and singing for their beauty.
All this makes Xiao Weiwei of Dandelion envious! How eager it is to be taken care of by uncle gardener! How eager tourists are to appreciate it more! How eager people are for bees and China to come! How eager the birds are to sing for it!
Xin Wei, a dandelion, thought: I will try my best to grow up. When I bloom, everyone will like me very much.
As the days passed, dandelion produced some light yellow flowers. It is blooming vigorously. I hope everyone can find its beauty and give it care and appreciation. It expects that one or two little butterflies will visit it occasionally, and no one seems to notice it. Dandelion is very disappointed. I feel that the whole world has forgotten and no one will like it.
"How come nobody likes me?" Dandelion is very depressed, and the more she thinks about it, the more unhappy she is.
A few days later, dandelion grew several white fur balls. This reminds it of the old man and grandmother who came to the park to beat Tai Ji Chuan every morning. They all have white hair. Dandelion thinks its white velvet ball is as ugly as the old man's white hair! Dandelion tried to look around, and no plant looked like it.
Everyone else is so beautiful. It's just that it has such an ugly white fluff ball. After thinking about it, dandelion completely collapsed. He felt extremely depressed and began to cry. It thought: I am the ugliest in the world now, and no one will like me. Thought of here, dandelion cried even more.
At this moment, a passing girl found it. The girl called her mother. The girl asked, "Mom, what is this?" Mother said, "This is called dandelion."
Dandelion found that someone had noticed it. It stopped crying at once and pricked up its ears to listen to the conversation between mother and daughter. The girl said, "Mom, this dandelion looks so special and beautiful!" " "No way! Dandelion couldn't believe her ears.
There are people in this world who praise it as special? Beautiful? Mother went on to say, "Yes, dandelions are beautiful! These white fur balls are dandelion seeds, and they will drift to new places with the wind, giving birth to new life.
"Mom, please help me take a picture with dandelion!" The little girl said, squatting beside the dandelion, smiling. Mother pressed the shutter.
Dandelion is so happy that I didn't expect anyone to take pictures of myself. The little girl said, "Mom, let me read you a nursery rhyme. A gust of wind blew and a small white velvet flower disappeared. Did the wind take away the gentle fluff, or did the fluff become a faint wind? ..... "The little girl and her mother walked away hand in hand, talking and laughing.
At this time, dandelion has been completely immersed in happiness, so it is so magical! It turns out that some people know how to appreciate themselves. Thought of here, dandelion is no longer as depressed as before. The sun shines warmly on it and the wind blows gently, which is very comfortable! Dandelion thought: Life is so beautiful, why haven't I found it yet?
Since then, dandelion has lived a happy life.
Extended data:
There are many ways of seed transmission, such as self-transmission, wind transmission, hydraulic transmission, bird transmission, mammal transmission, insect transmission and so on. The most important things are insect transmission (insect-borne flowers) and wind transmission (wind-borne flowers).
1, spread by water.
Plants that grow in or near water usually spread their seeds by water power, such as coconuts and water lilies.
Coconut: when the fruit of coconut tree is ripe, its shell is hard and hard, like a boat. After falling from the tree, it drifted away with the sea. When the tide washes it onto the island, new coconut trees will grow on the shore.
Water lily: When the fruit of water lily matures, it will fall into the water and slowly rot. Seeds covered with spongy exocarp will float on the water surface, drift with the current, and finally sink to the bottom to take root and sprout.
2. Spread by birds or other animals.
If you walk in the grass, many plant seeds or fruits will stick to clothes or trousers, or to other animals, or animal food, such as undigested seeds of birds, will be excreted and even taken to further places, such as Bidens bipinnata, Ficus, Plantago and so on.
Cherry, wild grape, wild ginseng: Birds or other animals eat seeds in their stomachs, but because they can't be digested, they are discharged with feces and spread in all directions.
Pine nuts: They were taken away by squirrels when storing winter grain. Pine nuts, hazelnuts and walnuts: In autumn, squirrels like to take these nuts away and bury them underground or in tree holes for preservation. Some of them will take root and sprout in the burial place before being eaten in spring.
3. spread by the wind.
Some seeds or fruits will grow hair or wing-like structures, which will float far away when the wind blows, such as dandelion, blackboard tree, Showa grass and so on.
Hongliu: It is the flying catkins that spread seeds far away. In spring, catkins fly everywhere. Do you know the mystery of catkins flying in spring? Grab a group of catkins and observe carefully, and you will find some small particles inside, which are willow seeds. Willow spreads its seeds far away through flying catkins.
Dandelion: The achene of dandelion in compositae has many long crown hairs. When it matures, these crests spread like parachutes, flying with the wind and spreading the seeds far away.
