The Story Composition of Plant Kingdom

The story composition of the plant kingdom is 250 words.

There is a mimosa in my home. I care about its growth. I go to see it every day. It has green spikes and pink hairy flowers. It is very beautiful. When it touches its leaves, it looks like a shy little girl. Its head is low and its leaves are closed. Do you know why? Let me tell you something. The petiole base of mimosa has an enlarged part called "leaf pillow". There are parenchyma cells in the occipital lobe. When the leaves are touched by the outside world, the vibration will be transmitted to the leaf pillow. At this time, the water in parenchyma cells immediately flows to the intercellular space, thus reducing the expansion ability of cells. The leaves close automatically, and the petiole and branchlets droop at the same time. After a few minutes of "calm", they recovered.

One day when I came home, I found that the leaves of mimosa had closed. I think someone must have touched it. I stretched out my hand to touch it, and my hands were cold. Ah, it's raining! I quickly withdrew my hand, closed the window and went to do my homework. The next day, I stayed on the balcony and read. The sky is cloudy and it's going to rain. Inadvertently opened the window and found that the leaves of mimosa were still closed and did not look up. I was surprised: I didn't see anything touch it. How do its leaves close? It began to rain cats and dogs, so I had to close the window and watch TV.

I waited and waited until a rainy day. I hurried home and rushed to the window sill with my schoolbag on my back. Ha, there is still a leaf not closed. I watched patiently and intently. After a while, a bug unconsciously bumped into the mimosa and flew away. At this time, something wonderful happened: the leaves of the mimosa closed. Seeing this, my heart suddenly opened up.

I am very happy because I have solved the mystery of mimosa leaves. With this "weather forecast", I won't get wet in the rain.

The mysterious composition of the plant kingdom

Students, do you know Nepenthes? No? Let me introduce you.

Nepenthes is a famous tropical insect-eating plant, mainly produced in tropical Asia. Nepenthes has a unique organ that absorbs nutrients-insect trap. The insect trap is cylindrical, and the lower part is slightly enlarged. Because it looks like Nepenthes, it is called Nepenthes. Hainan, the origin of China, is also called Leigong pot, which means like a hip flask. This kind of plant is called an insect-eating plant. It does not directly absorb nutrients needed to sustain life from inorganic fields such as soil, but lives by catching small animals such as insects. About nature-water, air, mountains, rivers, microorganisms, plants, animals, the earth, the universe and so on. , all belong to the category of nature; The science of studying nature is natural science, including mathematics, physics, chemistry, biology, geography and other sciences, and the branches of these sciences are very complicated, such as: biological science can be divided into microbiology, botany and zoology; Then it can be divided into molecular biology, cytology, genetics, physiology and so on. The intersection of various disciplines will produce many branches, such as biochemistry, biophysics, molecular structure biology and so on.

man and nature

Nature gave birth to human beings, which shows that it respects human behavior. On the contrary, human beings should respect nature more. On the surface, people are born of their parents. In fact, only when nature has the photon information of human beings can human embryos absorb this photon information from nature and grow into adults, that is, parents. At the same time, nature has completed the excitation of dark matter in embryos. There are 45336 species of vertebrates in nature, including birds 1244 species and fish 3862 species. There are more than 3 million species of insects, and only 1 10,000 species have been confirmed. Nature is a kind of natural resources, so people and nature should respect each other, maintain the attitude of cherishing and caring, make proper use of nature and prevent its destruction, so that the living environment is beautiful and the natural resources are inexhaustible, just like the mother and son are close and harmonious.

Therefore, the richness of information about nature can only be described as vast, and its complexity is not described by 30 thousand words or a few people.

Natural classification

There are all kinds of creatures in nature, including plants, animals, bacteria and fungi. At the same time, nature is also a place containing various ecosystems!

The elements of nature are divided into light, darkness, water, fire, wind, thunder and earth, which means that nature controls the balance of these things.

The composition of the plant kingdom 400-word mimosa

I heard that mimosa is a shy little girl. You will bow your head shyly when you touch it, but why? I came to the plant shop with curiosity and expectation, bought a mimosa and took it home to take care of it on the balcony.

After several days of cultivation, the leaves of mimosa finally grew up. Its leaves are green on the front and light green on the back, and there are some fluffy hairs on the meridians. After a few days, the buds of mimosa also grew out, round and purple, and some things like needles, which were very beautiful. Suddenly I had an idea to do a small experiment-touch the mimosa to see if it really closed its leaves. I touched it gently with my hand, and the mimosa really closed its leaves like a shy little girl. After about 30 minutes, the leaves of mimosa opened. I am very excited because the experiment was successful. However, I still have some doubts: why do mimosa close at the touch? I ran to ask my mother, and my mother said, "Because mimosa grew up in South America, where there are often storms and a lot of bugs, in order to protect itself, as long as anything touches it, it will close immediately." My mother also told me that according to the research of scientists, it was found that mimosa also has the function of defending against earthquakes! If the mimosa leaves were closed a few days before the earthquake, it means that an earthquake is coming.

Mimosa is amazing! As long as we observe carefully, we will find more mysteries of nature.

Composition of the plant kingdom

In a small flowerpot on my balcony, there is a humble mimosa.

The leaves of mimosa are oval, as light as small feathers and a little rough to the touch. This tiny stem is so fragile that a drop of water can bend it. When the wind blows, mimosa swings with the wind, just like a dancing girl. Its flowers are in full bloom, and the oval petals are purple. How like a little fluffy ball!

Once, I accidentally met a mimosa, and its green leaves were immediately put away and its petiole fell off. I squatted down curiously and found that after a while, the leaves of mimosa opened again and the petiole changed back. At this time, a question came to my mind: Why do mimosa put away its leaves after being touched?

I immediately moved out the extracurricular study materials, and after some careful searching, I found the answer: It turns out that there is an enlarged organ at the base of the petiole of mimosa called "leaf pillow", and there are many parenchyma cells in the leaf pillow, which is very sensitive to the outside world. Once it touches the leaves, * * * will immediately spread to the occipital bone. At this time, the cytosol in parenchyma cells began to flow into the intercellular space, which reduced the expansion ability of cells and led to the decrease of intercellular pressure in the lower occipital region, resulting in the phenomenon of closed leaves and drooping petioles. After a minute or two, the cell fluid gradually flows back to the leaf pillow, so the leaves return to their original appearance.

The above phenomenon of Mimosa leaves is the result of its long-term adaptation to the natural environment in the process of system development. Mimosa lives in tropical areas, where there are many storms. Therefore, in order to protect itself in the long-term harsh natural environment, whenever a storm comes, it immediately closes its leaves to protect itself from the storm, thus gradually forming this unique physiological phenomenon.

I thank mimosa, which brings me curiosity. I want to study hard and use this "key" to explore the mysteries of the plant kingdom and explore more knowledge.

There is a secret composition in the plant kingdom. Green radish and chlorophytum write a composition.

There is a secret ingredient in the plant kingdom from green radish and chlorophytum.

In the plant kingdom, there is a kind of flower that represents purity and dignity. It has beautiful and exquisite flowers. Its slender body is like a graceful woman, and its petals curl slightly downward. That is the fairy lily.

Lily leaves are dark green, just like a pair of hands, holding a sleeping bud in her arms. This naughty little Lei doesn't know when to show her cute little face.

After a few days, the lily bloomed and a faint fragrance came to the nose. I immediately ran to the balcony to observe the lilies.

The petals of lilies are oval. Its color is white, but it is also permeated with a hint of purple. It is full of bumps, and there is a little angel in a light green coat in the middle, which is full of bright colors in the breeze. But when it was most flourishing, the little angel was dressed in red, as red as the face of the sun. Just blooming flowers, white and flawless, a few small butterflies flew in and sucked fresh nectar. Where are the shy flowers? Dancing in the breeze in crystal white clothes.

After my investigation, I found that lily is no less noble than rose! You see, with the colorful colors of roses, Lily is also working hard! It is also the national flower of a country. It seems that the white crane is also a minor celebrity.

Ah, beautiful lily, may you grow more and more beautiful and thrive! (article

The secret composition of the plant kingdom

The secret of cactus, Liu Siqi: I have a cactus at home. This is a birthday present from my mother. I love it!

When the cactus just came back, I was very curious and couldn't help touching its "big slap" with my hand. Ah, it really hurts! My mother saw it and said to me, "Don't underestimate this cactus, it's amazing!" " "At this time, I began to study cactus carefully. How strange! You see, it is covered with small needles and palmlike stems like jade, which extend upward together. Like a pyramid, one piece of "green palm" stands on top of another, reminding me of tall and straight pine trees.

It is said that cactus is a drought-tolerant plant, which can survive tenaciously even in the desert called "barren land". In order to verify the truth of this sentence, I decided to do an experiment: water the cactus once and leave it in the yard for a month. A month later, I thought the cactus had withered, but I never expected that it was still standing vigorously. Looking carefully, the cactus in the flowerpot is green, and the palm-shaped stem not only does not turn yellow, but also grows several small buds. But why didn't cactus wither? I felt very strange in my heart, so I asked my mother, and my mother couldn't explain it clearly. As a physics teacher, she doesn't even know. Finally, I had to find the answer from the Internet. The answer is: cactus has a huge water storage system, and its palmlike stems and roots are the main "reservoirs" ...

It seems that there are many mysteries in the plant kingdom. I must study more various other plants in the future!

The 200-word plant kingdom has endless mysterious ingredients.

Fairy tales of the plant kingdom: about 252 words.

fairy tale

The rose queen in the plant kingdom received a report from Chrysanthemum: "Humans are going to destroy us all." The queen immediately called a meeting of the kingdom to discuss countermeasures. Rose said, "You can write a letter to mankind and state your interests." Everyone is unanimously in favor. Grandpa cycad said, "I'll write this letter." The main idea of the letter is that we hope that mankind will listen to advice and not destroy the plant kingdom.

Camellia volunteered to deliver the letter, and soon came back, angrily saying, "It was so arrogant that I threw it away without even looking." The queen said, "I don't know how good it is." Let's leave overnight. "

The next morning, when people opened their eyes, something terrible happened. It seemed to be on the moon overnight.

Then someone remembered the letter. So I wrote an apology letter.

When the Chinese rose queen saw that mankind had made a mistake, she ordered the earth to be restored to its original state. Since then, the plant kingdom and human beings have become best friends.

The mysterious composition of the plant kingdom, please the great gods.

A composition on the plant kingdom

These days, the drought girl is always in high spirits from morning till night, and her heart is full of joy. Can she not be flattered? No creature on earth dares to offend her. If anyone is not pleasing to the eye, she won't let it rain until you die of drought. So, all creatures are afraid of her. When you meet her, pretend to be smiling, say hello to her and please her.

However, Selaginella didn't take the drought girl seriously, and didn't even call her, let alone say hello. This really pissed the dry woman off. Selaginella, a little girl with a height of only about ten centimeters, will not give you some color to see see. I don't know the power of my old woman.

The arid woman chained her grandmother's rain and put her in the house. He tied Grandpa Sun to the solar car and pushed it from east to west every day for three months. The plants on the ground can't stand it, and many of them are dying. Selaginella is also very uncomfortable. He contracted the fan-shaped branches and leaves like a fist, and the color changed from green to yellow, which seemed to have a breath. Seeing that he was not dead, the drought girl pushed the solar car for three months in a row. Selaginella finally withered and burned.

The arid woman smiled coldly when she saw Selaginella die. What happened? Can't she? So, open the chain and let out the rain, grandma. Grandma Yu has a soft heart. When she saw the situation on the ground, it rained heavily. Unexpectedly, the dead Selaginella tried to drink water, finally woke up, re-opened its branches and thrived. It turned out that he faked his death.

Seeing Selaginella resurrected, the drought girl was so angry that she decided to give him some color to see. This time, she was dry for 8 months, and Selaginella died and lived until summer. After another 12 months of drought, Selaginella died and passed the summer. Let's just say that no matter how long you work, Selaginella is always like that. Play dead when you're dry, and be happy when you meet water.

After several tortures, the arid woman was exhausted, but Selaginella didn't care at all. The drought girl had no choice but to give up. "Why is Selaginella not afraid of me?" She asked her father Sun.

Grandpa Sun said: "Selaginella is particularly drought-tolerant. When you came, all the cells in his body were dormant, and his metabolism almost stopped, just like death. After you left, he drank water, and all the cells in his body recovered their life functions, and Xia came back to life. Therefore, humans call him' Nine Dead Resurrection Grass' and' Fairy Grass'. Although you are fierce, you can't beat him. "

Hearing this, the drought girl never dared to look down on Selaginella again!
