What lovely and interesting plants are there?

Dancing grass

As we all know, plants can't move, so how can they dance? But there is such a magical thing in nature, called dancing grass or dancing grass. It's called grass, which is actually a shrub of the butterfly family. It can grow to about 1.8 meters at the highest, and potted plants are generally tens of centimeters high. It has a rectangular leaf, and there is a tiny leaf next to this Ye Er, forming a palmately pinnate leaf.

The wonder of dancing grass is that its leaves can dance. If you play some beautiful music, or sing a few songs loudly beside you, its young leaves will slowly rotate with the melody, just like a little person dancing, which is very interesting. It is said that it likes songs with soft tone and bright rhythm, and beautiful songs such as There is a Beautiful Place.

Dancing grass is produced in Yunnan, Guangdong, Guangxi, Taiwan Province and other places in China, and also distributed in India, Vietnam, the Philippines and other foreign countries. Now it is very popular as a potted ornamental plant. If the child is interested, plant a pot, sing to it and watch it dance.

Viviparous plant

Mangroves covered with fountain pens

Generally only mammals are viviparous. Most plants are propagated by seeds, ramets and cuttings. Now, in order to produce a large number of commercial potted flowers, tissue culture is also used. These are common methods of plant reproduction.

Actually, there are many viviparous plants. That is, plants raise and shape their offspring on their own plants, and then let them live independently from their mothers. Mangroves on the tropical coast are now protected plants, which can prevent the coast from being eroded by waves and provide habitats for many small creatures. It is a complete small ecosystem. Mangrove seeds are very long and look like ballpoint pens. The locals call them "pen and ink boys". When the leaves grow to the top, they will fall off and stick straight in the mud. When the root grows, it is a little red tree.

So is the famous Rooting. This succulent plant first grows seedlings at the tip of the leaf, and when it grows to a certain size, it will fall to the ground. When the weather is wet, it will take root immediately and grow into a large piece.

There are also some plants, such as chlorophytum, butterfly lotus, fern, saxifrage and so on. It will stick out a twig or silk thread from the leaf and hang a small plant with an air root at the end. When it comes to wet soil, it will take root and sprout. If you leave it hanging, it is also very ornamental.

Hunters in plants

Nepenthes vulgaris

Plants are not all gentle "corners" slaughtered by others. We often see bugs eating holes in leaves, as if plants can't do anything about it. Many plants will also fight back, occasionally catching a few bugs to supplement nutrition. This kind of plant generally lives in the tropical rain forest, and their insect catching tools are also different, some are furry "clips" and some are covered "bags". If the bug accidentally enters its trap, it will be difficult for it to escape.

One of the most famous is Nepenthes. There is a tendril at the top of its leaf, and an insect catching bag shaped like a pot-bellied vase is hung at the end of the tendril. This bag has a removable lid at the mouth. Usually, the lid is half open and half closed, which can prevent rain and sundries from falling in. The bottom of the bag secretes fragrant mucus, which attracts insects to suck, but the "bag mouth" is very smooth, and the insects accidentally fall down and are stuck by the mucus, so they can't move. At this time, the "lid" will be closed quickly to prevent food from escaping. In this way, the worm will slowly break down into its delicious food.

After years of artificial cultivation, Nepenthes has gradually become popular and can be seen in some large flower and bird markets. Most of them are hanging cultivation, which makes their insect catching bags droop naturally, which is novel and interesting. However, most of the artificially cultivated Nepenthes have lost the ability to catch insects.

Insectivorous plants are rare species. There are about 600 known insect-eating plants in the world, which belong to * * *1family 2 1 genus, such as Nepenthes, Trapa, Lauracea, Nepenthes and so on. Most people live in alpine wetlands or lowland swamps to trap insects or small animals to supplement the lack of nutrition.

Writing a 600-word composition about plants, I feel that the pressure on trees is getting bigger and bigger, and I am accelerating my pace every day.

Walking between campus and home in a hurry, my eyes are always staring straight at the road ahead, and I can only see a few people who are in a hurry like me occasionally.

If it hadn't rained, I'm afraid I would have been in a hurry and didn't notice it at all.

The fine rain made the sky hazy and the dark clouds never dispersed. A gloomy day is a bit like my mood at this time.

I was walking mechanically on my way home when suddenly my umbrella tripped over something. I seldom look up. It turns out to be a bunch of branches.

I looked at the tree, but I couldn't move for a long time, because I couldn't help looking carefully. That is really a rare weak camphor tree.

Although the trees planted by the roadside are not particularly strong, this one is too thin. Even the thickest trunk can only be measured by one hand. The tender appearance has mottled bark that has experienced vicissitudes, and the branches are thinner, but there are many branches.

I think, maybe it is these countless twigs that drain the essence of the mother.

Looking up again, I was shocked. There are dense green leaves on such a weak body. After being washed by rain, it stands proudly, green and beautiful, like pure emeralds. I touched them and became very strong.

It is hard for me to imagine that such a thin tree will grow such beautiful and tough leaves. How much nutrition it has to absorb, how much wind and rain it has experienced, and how much effort it has to pay! Facts have proved that the weakest tree can also grow extremely beautiful and strong leaves.

I was moved by the tree, and I was ashamed of my inner darkness.

The young trees are poor, but they are not satisfied with this, so they try their best to absorb nutrients, grow hard and present their own beautiful side.

Maybe the firmness of the trunk is predestined, then the beauty of the leaves will come true, because branches and leaves are the pride of the tree.

Just like life, it will always give you such shortcomings. Please don't be sad, we still have a lot to make up for.

Family background is not high, self-cultivation makes the soul sublimate and the soul noble; The appearance is not outstanding, always treat people sincerely and make the mind beautiful; Parents have little power, respect each other as guests, take care of each other and enjoy family happiness.

Just like a tree, although the branches are small, it is also a shocking beauty to strive to grow lush leaves! I have long been far away from that tree, but my thoughts have not been recovered, but I am by the tree, paying tribute to it!

The 400-word composition describing plants is full of affection. As long as you observe it carefully, you will always catch it. For this reason, the school held a photo exhibition to appreciate family ties, 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! The legs were pushed hard, and the front legs were cleverly extended, grabbing the mother's arm, but the back legs were in the mother's pocket, and the whole action was done in one go, ruining the second photo. Dad is in a hurry.

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.

Write a 400-word composition about plants. On my balcony, there is a very humble cactus.

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, and 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 in various shapes, and sweet-scented osmanthus in ten miles ... but I love cactus which is not stunning in appearance, not only because of its appearance, but also because of its quality.

There are many kinds of flowers in the world, such as Magnolia grandiflora, Chinese 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.

If you write a 400-word composition about plants in the fourth grade, the material of cactus is better and you can change it.

On my balcony, there is a very humble cactus.

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.

Mimosa One day, my father and I went for a walk and saw a grass.

This grass is green, and its leaves are a bit like Metasequoia. From a distance, it looks like a beautiful piece of jade, very beautiful.

I asked curiously, "What grass is this?" Dad looked at it carefully: "This is a mimosa.

""I heard that the leaves of mimosa will close after being subjected to * * *! " I asked with interest.

"Then you will know if you try!" Dad reminded me.

I touched the leaf carefully for fear of hurting it.

Sure enough, the leaves of mimosa are like a pair of separated palms, and they close quickly.

I was very excited when I saw it.

But why are the leaves of mimosa "shy" after receiving *? ! A big question mark came to mind.

He asked his father, "Dad, why are mimosa shy?" "Want to know the reason? Check the information yourself! " Dad is obviously playing the suspense.

Hum, just check! We are not "all talk and no practice"! As soon as I got home, I couldn't wait to surf the Internet.

I finally found the answer: it turns out that there is an enlarged organ at the base of its petiole called "leaf pillow", in which there are many parenchyma cells, which are very sensitive to the outside world.

Once it touches the leaf, * * * will immediately spread to the occipital, at this time, the cytosol in parenchyma cells begins to flow to the intercellular space, which reduces the expansion ability of cells, reduces the intercellular pressure at the lower part of the occipital, and leads to the phenomenon of leaf closure and petiole drooping.

1-2 minutes later, the cell fluid gradually flows back to the leaf pillow, so the leaves return to their original appearance.

The "shy" action of mimosa may be a survival instinct of mimosa to protect itself.

Because the mimosa originated in the tropical region, where there are many storms, when the storm blows the leaflets, it immediately closes the leaves to protect them from the storm, thus gradually forming this physiological phenomenon.

Dear friends, let's explore the mysteries of biology together!

My hometown is Linze, where there are beautiful scenery and rich specialties. Especially Linze jujube is famous all over the world, and there are countless jujube trees.

But my favorite is the apple tree.

The apple trees in my hometown are tall and big, with thick trunks and dark brown bark.

Look, those leaves are so bright green, and the stem stretches out its thick green arm, waving to people! There are many lovely red apple faces under the green leaves.

When the warm spring breeze blows gently, the apple tree grows new branches and small green leaves.

In a few days, the leaves grew up and turned dark green.

The warm spring breeze blows gently, and birds are singing in the branches. That sounds really good.

When the strong sunshine shines on the earth in summer, apple trees grow more vigorously.

The leaves of a tree seem to be dyed green by the wind girl, so cute.

There are many small green apples on the tree. They are growing quietly.

When the autumn wind sends the message of harvest to people, the apple is ripe.

They hang high on the branches to show people their beauty.

The bright red color makes us greedy cats salivate.

Before the adults came to pick it, we had climbed the tree secretly and picked some in our arms.

Find a place where no one is there, and the smell tempts people to take a bite before scrubbing.

Ah! Sweet and sour.

Apples were picked one by one, but the leaves of the tree gradually turned yellow and danced gently in the air, and the tree was already golden.

When the crystal winter snow fell from the sky, all the leaves of the apple tree had fallen.

The apple tree covered with snow clothes stands proudly in the biting cold wind, announcing to people that I will bloom more flowers and bear more fruits in the coming year.

I love apple trees in my hometown, and I love my beautiful and rich hometown even more.

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 small 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.

One night, my father and I went to the field to observe plants.

We came to the cornfield first, and my father tore off a leaf and showed it to me. Then he pointed to the veins on the leaves and said to me, "Look at its veins, son. This vein is called parallel vein, and its root is fibrous root, which is the characteristic of monocotyledonous plants. "

Dad said, showing me the corn roots in the field.

I don't know what a monocotyledon is. Dad also told me that the seeds of monocotyledonous plants have only one cotyledon, such as corn, rice and wheat.

Plants such as peanuts, soybeans and peas have two cotyledons, which are called dicotyledons.

We walked and came to a vegetable field. My father pulled up a side dish and handed it to me. Let me compare it with just now.

Dad said, "The veins of dicotyledonous plants are called reticular veins. Its root is a straight root, and it has a main root.

This is the characteristic of dicotyledonous plants. "

Dad then told me that plants are divided into angiosperms, gymnosperms and ferns. The monocotyledons and dicotyledons we just saw belong to angiosperms.

Angiosperms are also called green flowering plants. All flowering plants belong to angiosperms.

The seeds of angiosperms are wrapped in peels, such as peanuts, and the seeds are wrapped in peanut shells.

If there is no pericarp outside the seed, then the plant is called a gymnosperm, such as conifer. After seeing angiosperms, my father took me to find ferns.

We searched for a long time and finally found some unknown plants in the corner behind a house. Dad took it apart and handed it to me.

Dad said he didn't know its name either, but he knew it was a fern. Pteridophytes have no seeds. They reproduce by spores.

Dad also said that when it has spores, he will show it to me and let me know what spores are.

By this time, it was already dark. Dad said, "Son, it's getting late. Let's go home. " .

I took out a specimen of a fern and went home with my father.

When I got home, I asked my mother with a specimen. My mother said it was a fern. I asked my mother how she knew. My mother said that she graduated from biology department. If she didn't know this, she wouldn't have to be a science teacher.

At this moment, my father called me. It turned out that my father soaked several soybeans and buckwheat in water, and let me compare their cotyledons.

Through observation and comparison, I can already understand dicotyledonous plants and monocotyledonous plants.

I like observing plants.

The combination of plants must be beautiful. I like flowers very much. The beautiful appearance of flowers often amazes me, and the charming fragrance often intoxicates me.

I have seen many exotic flowers and plants: roses, peony flowers, daffodils, lilies ... but what I can't forget most is the Chinese rose flowers that can be seen everywhere.

The stems of Chinese rose are thin and long, and the dark green stems are covered with many dark red thorns.

These small thorns are sharp and hard, I think: this may be its self-defense weapon.

The mosaic is palm-shaped, green and dripping, with a row of pinion gears on the edge.

Spring is the season when Chinese rose flowers bloom. These flowers are as bright red as fire, as orange as gold and as white as snow ... showing great vitality.

Petals roll down slightly, layer upon layer.

In the bright sunshine, the petals are like a layer of bright oil, shining, and the roses hold their heads high, like a victorious general.

They greedily suck the spring rain and enjoy the sunshine bath. The golden stamens in the middle of the petals are stuck with pollen at the top, giving off a strong fragrance, attracting groups of butterflies to play among the flowers. Since then, bees have been trying to collect honey from flowers and buzzing.

When you are exhausted after a hard day's work, smelling the flowers will make you refreshed, and your boredom and fatigue will suddenly disappear and you will be full of energy.

A breeze blew, the Chinese rose swayed in the wind, and the beautiful figure danced like a girl.

I have seen the elegance of roses, the wealth of peonies, the elegance of daffodils and the beauty of lilies, but these gorgeous feelings have been conquered by the simple and natural beauty of Chinese roses.

Ah! I love this simple beauty-Chinese rose!

The plant I am most familiar with is cactus.

There is a cactus in my home.

My mother bought it from the flower stand in front of the supermarket.

There were no leaves when I first bought them, and a few months later I grew a pot full of green, so cute! I often go to see it, water it and loosen the soil.

There are many thorns on the palm of cactus. I accidentally got stung by it when I watered it. It really hurts! I gradually developed an aversion to it. I feel too stingy. In order not to let others touch me, I grew nasty thorns to protect myself.

Whenever I get stabbed, I won't water the soil every other week.

Once, I came home from school to do my homework and smelled the flowers.

I'll check the balcony. Where are the flowers? At this time, my eyes fell on the cactus in the corner, and I saw the green "palm" covered with dust, with three small yellow flowers on it! Isn't that strange? It's blossoming without eating or drinking for so long? I grabbed the kettle and ran to the faucet, and decided to let it drink enough! I filled a basin with water, poured enough water on the cactus from top to bottom, and the cactus showed green again. Really beautiful! I really like cactus!
