The cactus's body is like a piece of jade and a cute little hedgehog. It is covered with thorns like steel needles. Don't underestimate these thorns. This is the weapon it uses to defend itself and fight back! I was stabbed by it, and my mother was stabbed by it, which was very painful. My mother tried to throw it away many times, but I refused because I had a special feeling for it. I like cactus.

Spring came, everything woke up, and a small cactus was drilled on the cactus "mother". The cactus looks so delicate, as if a gust of wind could blow it away. And its "mother" is afraid that her children will be "bullied" by the cold wind in early spring, and always blocks the cold wind with her body, but the cactus always climbs up. Finally, with the encouragement of Grandpa Chun Lei and the help of Sister Chun Yu, the cactus overcame many difficulties and grew up.

In late spring and early summer, cactus grows buds. Strangely, cactus blooms in a "sequence", always two flowers bloom together, like a pair of twin sisters, like a bow tied on the little girl's head. Cactus flowers are white and fragrant, like a beautiful fairy wearing a white dress, dancing gracefully on the jade stage, and emitting intoxicating fragrance from the dress.

Autumn, the harvest season, cactus grows up, its use can be much more! You can cut into pieces and soak them in cool and delicious tea to quench your thirst. Edible, nutritious, and can also be used as a bonsai ... one after another, but the most surprising thing is that it can be boiled into medicine to treat diseases.

People love magnificent peonies and peonies, autumn chrysanthemums of various shapes, and sweet-scented osmanthus flowers of ten miles ... but I love the cactus with a humble appearance, not only because of its appearance, but also because of its quality.

Today, when I came home from school, I saw the plant "cherry radish" that my mother bought for me on the coffee table. Wow! I'm so happy! Hurry up and hug your mother and say, "Mom, thank you!" " "Immediately, the two of us began to work.

My mother and I unpacked the plants first.

I saw a beautiful yellow flowerpot, a bag of seeds like melon seeds, a bag of fertilizer and a big bag of culture soil like pepper powder in the box. How can this soil make the soil in my balcony flowerpot different? There is also an instruction manual.

So we followed the instructions step by step, and I was my mother's little helper.

Step 1: Mom cuts open the culture soil with scissors and pours all the culture soil into the flowerpot.

Step 2: Mom sprays the soil with a watering can until the bottom of the flowerpot is permeable.

Step 3: Scatter the seeds evenly on the surface of the culture soil. This time, I watered the seeds to absorb enough water.

Finally, cover it with a paper shell according to the instructions, so that you can't see the sun these days.

My mother also told me that the cherry radish should be kept ventilated for a few days when it germinates, and then the windowsill or balcony should be removed to expose it to light when the sprouts are strong.

I silently wish the cherry radish to sprout quickly.

Works describing plants

Plants are alive, with fresh life.

Scientists have done such experiments.

If you keep playing beautiful light music to a plant, the flowers will be brighter and the fruits will be more, bigger and sweeter.

On the contrary, plants of the same genus will wither and die quickly if they keep making noise.

Let's ignore these experiments for the moment.

However, there is an indisputable fact.

That is, when we break a plant, it will shed juice, and I think it is their painful tears.

I once read an article by Jia Pingwa entitled My Teacher.

Laughter, but also gave birth to some serious thinking.

The article wrote: "My teacher Sun Hanbo is the son of a friend. He is three and a half years old this year.

On the outing, adults picked a bunch of flowers for the children.

Speaking of him, he didn't answer, his small eyes turned white and his nose flapped one by one. He said, "Does the flower hurt?" "In this article, there are many such feats.

In my opinion, this little boy is no worse than the little boy who is determined to be the president of the United States in 2032.

This really shocked me.

This three-and-a-half-year-old boy is really smart and knowledgeable.

It seems that not only Jia Pingwa wants to call him a teacher, but he is also our adult's little teacher! The proposition involved by this little teacher is an important topic that human society must face today-how can human beings coexist and prosper with plants? Plants are the oldest inhabitants on the earth.

"380 million years ago, the earth was covered with tiny mosses, lichens and other small plants. However, with the evolution of ecology, the appearance of trees has completely changed the environment of the earth. The original trees absorbed nutrients from weathered rocks at an unprecedented speed, which aggravated the weathering of rocks.

Because of this process, the carbon dioxide in the atmosphere decreases, and because of the increase of photosynthesis, the oxygen in the atmosphere increases, which reduces the greenhouse effect and makes the earth cool.

Plants have multiplied on the earth for hundreds of millions of years, and some plants are also called living fossils.

And humans have only been born for hundreds of thousands of years.

According to the latest research data just released abroad, it is only a few million years old.

Plants are beautiful: this is a beauty of truth and individuality, a beauty of diversity and richness, and a beauty full of competition and evolution. In a word, the beauty of plants is a kind of natural beauty, which is endowed by the creator with all the mysterious natural beauty here.

Her beauty is intoxicating, fascinating, feathering and ascending to fairyland.

It is a large number of various plants that beautify the common home of mankind.

As human beings, we have a misunderstanding that the plant kingdom is a lifeless world.

In fact, the plant kingdom is also a life world, and it is also a life world with which human beings should live in harmony.

We humans are forgetful, or simply turn a blind eye: life originally existed only in the plant kingdom, and plants are the ancestors of life on earth.

The plant kingdom provides us with the climatic conditions for survival and evolution, as well as all the living materials related to food, clothing, housing and transportation.

We never think that protecting plants means protecting life, protecting our own living environment and protecting ourselves.

When the grasslands, forests, mangroves and swamps on the earth are slowly disappearing, people's lives will become more and more embarrassed: the loess plateau is denuded, the desert is spreading, the rivers are cut off, and sandstorms are rolling in.

Today, the species of plants are still decreasing year by year, and some even disappear forever.

I think their last message, their swan song of life, must be: We have always been your friends, but how can humans burn the bridge and treat us so mercilessly? Then, one day, when you humans taste the bitter fruit, you will deeply regret and miss us.

400 words of plant composition in the fourth grade of primary school

Cactus is a desert plant. I admire its tenacious vitality.

Let's take a look at its introduction first! Cactus is dark green all over. If you look closely, you will find clusters of white thorns on its oval thick stem.

This little thorn is its leaf. If it stings you, you will "ouch" for a while.

This may be its weapon to protect itself.

Although the cactus looks ugly, if it is open, it is better than Bai Mudan, as if it is decorating itself.

Flowers as white as jade are also fragrant, which really makes people want to pick one.

But at this time, the small thorn will remind you "just look, don't start work!" Although the flowering period of cactus is very short, it will wither in only one day, but its vitality is very strong.

Whether summer is "scorching sun" or not, as long as it is planted in the soil and left unattended for a few days. Even in the "freezing and snowing" winter, it will not change color and grow tenaciously.

Cactus is a cactus, which is the general name of spherical species of cactus plants. It is not only varied and complex, but also has unique and colorful shapes. It is a pearl in a hundred flowers garden.

If you pay attention to the taste, you can plant some kinds of cactus, such as Jinhu, Feipeony, Dragon Ball and Moon Palace.

However, those ordinary cacti also have a "taste". They have strong habits and are easy to cultivate. Flower pots, pottery pots, porcelain pots, purple sand pots and plastic pots are all acceptable. The fertilizer is the residue of plant ash, Taomi water and yogurt.

I hope you don't underestimate cactus. Although the variety is common, the flowers are still beautiful and will not disappoint people.

However, what makes people sigh is not the beautiful flower season of cactus, but the breeding period of its big balls and small balls. Watching the little balls attached to the mother gradually change from small to big, the thick maternal love is also very touching.

When the melon is ripe, these young eggs will leave the mother's body and open up their own world. Although I am silent, people who like to grow cactus will certainly not turn a blind eye to all this (I am just stupid and can't describe it).

A horizontal couplet depicts the following: the baby fell to the ground.

I think it is not only vivid, but also full of puns and fun.

Haha, there are actually many kinds of cactus, so I won't introduce them here.

Write a composition about interesting plants (60 words)

Mimosa this summer, I lived in my grandfather's house for a few days and found several mimosa trees planted in his house. Mimosa is about 20 cm tall and has very small thorns on its stem. Its leaves are oval, with a total of 32 small needles. Mimosa leaves are very interesting. As long as your hand gently touches its leaves, it will be put away shyly like a shy little girl. Why are mimosa shy? I opened it. In this book, I found the answer: the petiole base of mimosa has a swollen parenchyma tissue-leaf pillow, which is filled with water. When people touch the mimosa with their hands, the leaves vibrate, and the water in the cells under the leaves immediately flows to the upper and both sides, making the leaves relax like a deflated ball. What an interesting phenomenon!

Phototropism of plants Do you know the phototropism of plants? Do you know why plants grow in the direction of sunlight? I mentioned in the magazine We Love Science that plants will grow in the direction of light. In order to prove this statement, I decided to do my own experiments to verify it.

First, I prepared a mung bean seed, a vegetation filled with soil, a small cardboard box and three pieces of cardboard. Then I buried mung bean seeds in the soil, and then separated several squares in the paper cup with cardboard to form a simple maze. I opened a window on one side of the carton, put the paper cups in the corner of the carton away from the window, and finally sealed the carton and put it on the balcony.

Two weeks later, mung bean sprouts poked their heads out of the small carton window! I quickly opened the carton and was shocked by what I saw. It turns out that mung bean sprouts go around the cardboard maze to the window.

Why is this? It turns out that plants are phototropic.

The phototropism of plants is due to uneven auxin.

Auxin also refers to the growth hormone in plants, which can promote the growth rate of plants, but it doesn't like sunlight, so it is always hidden in the backlight of plants.

If there is too much auxin on the backlight side, the growth speed of plants will be accelerated and plants will bend to light.

Other plants will "catch up" with the sun, such as sunflowers. The leaves on its stem can get more sunlight and accelerate photosynthesis. Flowers can spread pollen by catching light and attracting more insects, thus making themselves more colorful and fragrant.

The most sensitive parts of plants to light are tender stem tips, embryo tips and seedlings.

They can even capture the faint light visible to the naked eye.

This is the secret of plants growing towards the sun!

Ask to write a short essay describing plants (use contrast and support to express your wishes)

I praise the grass, and everyone is familiar with it. You can see it on dusty roadsides, on barren hills and even in narrow and humid crevices. It is the messenger of spring and a new beginning. I praise the grass, it is so different. The grass is so fragile that even a drop of dew can keep it low. It is not as tall as a big tree. Grass broke through the ground, tender and green, and spread all over the earth. They unite together, and countless grasses gather together, putting bright green clothes on the earth, sending away the dryness and monotony of winter and bringing color and hope. I praise this grass, it is so different. Grass has never asked for anything from people, but it has made so many contributions to people. In order to prevent the Yellow River from flooding, we must first strengthen the soil and water conservation work in the middle and upper reaches. In this work, grass is the first hero, and many grass roots form a network underground, forming a solid defense line. I praise the grass, it is so different. Grass is fragile, but when summer comes, storms can blow away branches and make flowers wither, but there is nothing to do with grass. Even though it was washed away by the storm, it stood still. I thought of grass. That kind of unity and cohesion, that kind of dedication and that kind of indomitable spirit are exactly what Chinese descendants have. "How can you see a rainbow without experiencing wind and rain?" Let's fight for a better tomorrow like grass. I praise the grass.

Write 400 words about plants.

There are several mimosa plants on the lawn of our community. I pay special attention to them because they are different and arouse my curiosity.

In spring, the mimosa sprouts, green, and the pole is only 1 to 2 decimeters long.

In summer, mimosa is luxuriant in foliage and leaves are very strange. It is a very thin stem, and there are some fine things like small needles on both sides, much like the leaves of Metasequoia glyptostroboides.

In autumn, mimosa blooms, and the flowers are fluffy, pink and purple.

Although it is small and unremarkable, when you look closely, you will find it beautiful and lovely. This is a delicate beauty, very charming.

In late autumn and early winter, mimosa will bear fruit, just like lentils, with a green shell outside and seeds inside.

After a while, the shell turns brown. Soon, the seeds jumped out of the shell and landed on the soil. When it takes root and sprouts next spring, it will reproduce from generation to generation, and its interest rate is no different from other plants.

What makes people wonder is why the leaves droop and close when they touch it. I was puzzled, so I had to look for information on the Internet.

It turns out that mimosa once lived in the desert, and tornadoes often appeared in the desert. When the sand rolled up by the wind touched the leaves of mimosa, mimosa felt very painful and the leaves closed.

In the long run, it will become grass that closes as soon as it touches leaves.

There is a pouch for storing liquid on the stem of the petiole of mimosa, just like an oil cylinder in a hydraulic press.

Usually, the bag is full of liquid. When you touch the leaves, the liquid in the bag flows to the upper and both sides of the leaves, and the leaves close under the action of gravity. Calm down for a while, the liquid slowly flows back into the bag from both sides, and the leaves spread out again.

Sometimes, I touch them on purpose and make fun of them.

My cactus has a flat stem with many thorns on it.

I once heard the teacher say that cactus has adapted to the desert climate, its leaves have turned into thorns, its stems have become fat and fleshy, and it has grown a lot of hair.

Its stem is enlarged because it needs to store nutrients in rainy season and reduce water evaporation in dry season.

I was shocked by its "survival of the fittest".

However, what shocked me even more was an incident that happened in the summer vacation.

I remember that during the summer vacation, my cousin, four years older than me, came to visit, and somehow a sore grew on his foot, which made him cry and scream, which can be said to be fidgeting.

Later, my mother didn't know which book to find a remedy: cut cactus into pieces, mash it and apply it to the sore.

I cried as soon as I heard it. "Want to cut my baby? No! " My mother and my brother prepared for a long time before I promised them to cut a piece.

After a few days, the sore on my cousin's foot really disappeared.

I thought, "This method is clever, but my cactus is definitely going to die."

A few days later, the "wound" of cactus slowly dried up and healed, leaving only a white scar.

At this time, I can't help but respect cactus.

A composition about plants

Sunflower There are many kinds of flowers in the world, such as Magnolia grandiflora, Rose, Rose, Plum Blossom, Chrysanthemum, Clivia, Camellia and so on.

However, the flower with the most flowers and the richest colors belongs to the sunflower.

As the saying goes, "good flowers don't bloom often."

Sunflower is also a good flower, including red, yellow, white, purple, crimson and orange ... Sunflower petals are single-layered, shaped like plum blossoms, with a red core and yellow spots on black filaments.

Sunflower stems are long and thin, soft and curved.

It has thin branches, dense leaves and many flowers.

Sunflowers only bloom when they see the sun. Every day when the sun rises slowly from the east, sunflowers are scrambling to open their smiles.

When the breeze blows away, the sunflower "shakes its head", as if reading a poem and nodding to pedestrians.

The flower bones of sunflowers are red and the shape is the size of soybeans.

Unlike other flower bones, they are short and round.

Sunflower seeds are surrounded by several small leaves.

Flower seeds are as big as sesame seeds. When the seeds of small flowers are ripe, they are scattered in Grandpa Earth's arms. After being nourished by sunshine and rain, they can grow more beautiful sunflowers in the second year.

Sunflowers are full of vitality. She sucks the nectar that Grandma Blue Sky gave her and greedily absorbs the nutrition of Grandpa Earth.

Sunflowers thrive under the care of Grandpa Earth and Grandma Blue Sky, making the motherland more beautiful and adding icing on the cake to the beautiful nature.

Sunflowers at night are like a child playing all day, tired and gratified to enter a sweet dream.

Morning glory is also a good flower. It blooms early and fails late. It and sunflower seem to be a pair of good sisters. They agreed to open up together, enter the sweet dream country together, not early or early, and decorate this beautiful nature together.

They are selfless and never ask for the return of the motherland and the appreciation of the people. Although sunflowers are not as noble as roses, as fragrant as chrysanthemums, as pure and elegant as Magnolia grandiflora and as fragrant as plum blossoms, they have the spirit of selfless dedication.

I love sunflower, its tenacious and vigorous vitality, and I love its selfless dedication.

Affection is everywhere, as long as you observe it carefully, you will always catch it. For this reason, the school held a photo exhibition about the family, and I spent a lot of effort.

That night, I thought hard all night.

But I still have no idea.

The next day, I forgot, because I had a lot of homework. I didn't remember it until seven o'clock on Sunday evening. I took a few photos at once and forgot to bring them on Monday, but I was inspired a lot that day. When I got home, I finished my homework in a hurry. Because my mother is afraid of damaging her image, I am in charge of photography.

But she won't use the touch-screen camera that Dad just bought from Hong Kong. I can't help it

I spent another night teaching her how to use it.

Tuesday night, we can finally start shooting. Dad cut his hair and changed his clothes, but the dog and pig have long gone to bed, but today they are particularly energetic. His eyes are shining, and he is not tired. He shook off a pile of fleas in the form of Mao Mao rain. Pigs are still young and need to be led, otherwise rabies will be endless.

Great, my father put it down and growled at me. I even yelled at cheating and introduced it into the cage. After a while, it knew that it had been cheated, and it cried angrily ... I was upset and liberated it. I immediately made a good move with my father. My mother just wanted to press the shutter when Pig jumped into my father's arms in one stride. What a waste of expression. I am angry and funny. Put the pig down first. Dad did it.

But it didn't last long. Pig seems to be interested in the camera and thinks it's for him! With a hard push on both legs, the front legs reached out skillfully and grabbed the mother's arm, but the rear legs were inserted into her pocket. The whole action was done in one go, ruining the second photo, and now dad is anxious.

I'll chop you up and eat meat, a small sample, but the pig won't change, and I can't help it. In the end, I can only agree that dad will take care of it and mom will take pictures.

What about me?

Just sitting and watching, I heard a click, the flash was on, and the pig was scared to hide inside. When dad was in a hurry, he grabbed the click and recorded this beautiful moment.

The next step is to take it to the computer. This photo representing the family will definitely stay in the computer, and my parents' love for me will definitely stay in my heart.
