1. When writing about plants, which kind of plant is good?
Plants - Narcissus
When I was a child, I always lived at my grandma’s house. At that time, there were many beautiful flowers planted in my grandma’s yard. In spring, there are winter jasmine and peonies; in summer, there are sunflowers and crab claw lilies; in autumn, there are chrysanthemums and bunches of red; in summer, there are wintersweets and daffodils.
Among them, I like the narcissus the most, I like its appearance and even more its "inside". Although it is not as delicate as a peony, not as red as a sunflower, not as eye-catching as a chrysanthemum, and not as fragrant as a wintersweet. But the narcissus stands gracefully and gracefully, and the narcissus is pure and clear. There is a bigger reason: "Daffodils have tenacious vitality."
Narcissus is known as the "Lingbo Fairy". Indeed, its charming appearance makes people fall in love at first sight.
Those pots of daffodils at my grandma’s house are so beautiful.
In January, the daffodils are blooming! Its emerald green leaves are so luminous and bright that among the criss-crossing green leaves, there are several small, flawless white flowers blooming in an orderly manner, with a golden stamen embedded in the flower. The faint fragrance looks particularly elegant. Narcissus has nothing to do with soil, and Yuhua Stone is its "soil". I thought: I want to be as pure and white in thought as it is, without any mud. The root of the narcissus is like a big onion, with white roots growing under the roots. They are like long earthworms surrounding the hard rainstones, and they look very stubborn.
A gust of wind blew by, and the little flower shook its head and swayed its soft body, as if wearing crystal clothes and dancing on the water and stones, which made people feel relaxed and happy.
In winter, many flowers cannot withstand the ravages of the severe cold and the test of fate - they wither. But the narcissus is not afraid. When it is freezing cold and snowy outside, it stands proudly, still full of energy and vitality, as if it is fighting the cold wind. It is so perseverant that people love it more and more. .
I love daffodils! Love its beauty and fragrance, love its nobility and purity, and love its tenacity even more! 2. Write a composition about the characteristics of plants
Cactus is a unique tropical plant with very tenacious vitality.\x0dThe potted cactus has an astonishing indomitable character, with or without water, weather or weather.

Another piece of "green" grows out of a "green palm" "The little hand is long", which makes people have a lot of reverie. It stands vigorously in this posture wherever it grows. In the hot and dry summer, other potted plants have lowered their heads, but the cactus raised its head like a warrior. , looking at the blue sky; in the bitterly cold winter, other potted plants have long been taken indoors by their owners, but the cactus has withstood the wind and frost and is not afraid of the surrounding environment. It is never particular about it. Once it takes root, It's like saying: "This place is great, let's grow here!" The immortal is covered with hard thorns, and any wild beast will stop immediately when it sees it. If pests want to bite it, its body will always be riddled with holes.

Its noble quality of selfless dedication is so admirable\x0dRefer to "Middle School Student Composition". 3. What should I write about plants?
Let me introduce maple trees: Sugar maple forests are found all over Canada.
It is also called the sugar maple tree. Every year in late autumn, the golden wind blows, and the bright red maple leaves are as bright as the morning glow. The color is delicate and very magnificent, just like the red flowers blooming in spring. Canadians have a deep affection for the maple leaf and regard the maple tree as the national tree. Canada is known as the "Land of Maple Trees".
The sugar maple tree is one of the more than 140 species of maple trees in the world. The sugar maple tree is a deciduous tree with a tall tree shape, some reaching a height of more than 40 meters and a diameter of 40 to 100 centimeters.
The leaves are alternate, serrated, palmate, usually three-lobed, and five-lobed on young trees. Sugar maple trunks contain a lot of starch.
In the cold winter, it turns into sucrose.
After the second spring, the temperature increases and the sucrose turns into sweet and flowing sap.
At this time, people drill holes in the trees, and sugar liquid will flow out of the holes. Sugar maple sap contains 3 to 5% sugar, and some can reach 10%.
A 15-year-old sugar maple can produce about 2.5 kilograms of pure sugar a year, equivalent to 25 kilograms of sugar per acre, and can produce sugar continuously for more than 50 years. It is known as "hardcore sugar cane" because it can be grown in one year, benefited for many years, and the yield is stable.
The sugar made from this sap is called "maple sugar" and "maple sugar". Maple sugar contains about 85% sucrose, and the rest is fructose, glucose and some special aromatic substances, which have a unique flavor.
Its nutritional value is comparable to that of honey. It has the effect of moistening the lungs and appetizing. It is used as a raw material for making cakes, soft candies and hard candies. It has a suitable sweetness and is fragrant and delicious. Among the more than 10 maple varieties in Canada, the most famous are sugar maple and black maple, which are the best raw materials for making syrup.
Quebec and Ontario in southeastern Canada are the two provinces with the most maple forests, where there are thousands of farms producing maple sugar. Starting in March every year, Canadians happily celebrate the traditional Sugar Maple Festival and taste the sweet food that nature has given them.
During the Maple Festival, the farms that produce maple sugar are all decorated, people put on festive costumes, sing and dance, and hold various activities to celebrate the harvest. A large number of tourists came to share the joy with them.
On weekends, some farms provide free maple syrup cakes and "toffee" (a cup of white spring snow, then poured with hot syrup, which has a great color and fragrance) for everyone to taste. The Maple Sugar Festival often lasts for more than a month.
Canada is the country that produces the most maple sugar in the world, with an annual output of about 32,000 tons. In addition to its own consumption, it also exports a large amount of maple syrup. The Canadian people revere the maple leaf. There is a bright red maple leaf in the center of Canada's white rectangular flag.
The maple leaf has become a national symbol. In 1860, when Prince Charles of the United Kingdom visited Canada, people welcomed him with fiery red maple leaf decorations.
In Canadian daily life, maple leaf patterns can be seen everywhere. The maple leaf is palm-shaped with 5 shallow lobes, 13 cm long, slightly wider than long. The 3 largest lobes have a few protruding teeth. The base is heart-shaped, the upper surface is medium green to dark green, and the lower vein axils are hairy. They change color in autumn. It is yellow to orange or red.
The bark is grey-brown and smooth, with grooves and scales appearing as the tree ages. The flowers are yellow-green, small, without petals, and hang down from the slender stalk. They bloom with the young leaves in spring and form an open inflorescence.
The fruit has parallel wings and is 2.5 cm long. Height 30 meters, wide columnar shape, deciduous leaves.
The white sugar, brown sugar and rock sugar we usually eat are mainly made from sugar cane and beet. Using the sap secreted by trees to boil sugar is still new in our country.
Among the forest trees in the temperate regions of North America, there is a type of sugar maple tree that can secrete sugar liquid, commonly known as maple tree, of which Canada is the most famous. There are several varieties of sugar maple trees, such as sugar maple, silver sugar maple, and brown sugar maple. The former two species are famous for their sugar production.
The wood of maple trees is used as building materials or equipment materials, musical instrument materials, sculpture materials, etc. It can also be planted for ornamental purposes. Planted for harvesting and used for fire.
In traditional Chinese medicine, root bark and branches are used in the medicinal materials of chicken feet. When the knee joint attacks, put it in water and then take it; when the fracture occurs, ogapy is used (the author is not sure yet) , which is provided by the information) use; has anti-inflammatory and detoxifying effects. Canadian maple (Aceracede) (also known as sugar maple) Maple trees accumulate starch during the growing season.
As the snow melts in the spring, enzymes convert starch into sugar, which dissolves in the water absorbed by the roots, creating a slightly sweet taste. Maple sap contains water (approximately 97%), minerals, organic acids, and maple flavor.
Starting from early March, the sap will flow in the tree's body for 6 to 8 weeks, promoting the growth of the tree. All trees produce sap, but maple trees produce more and sweeter sap.
There are more than 12,000 maple sugar producers in Canada. Canada accounts for 85% of the world's maple sugar production, and the United States accounts for 15%.
Quebec (93.3%), Ontario 5.5%, New Brunswick (1.1%) and Nova Scotia (0.1%) are rich in maple sugar. According to Canadian data, Canada's maple product production in 2000 was 40,196 tons (88.4 million pounds), and the expected agricultural output value was 151.5 million.
Maple trees accumulate starch during the growing season. As the snow melts in the spring, enzymes convert the starch into sugar, which dissolves in the water absorbed by the roots, creating a mildly sweet flavor.
Maple sap contains water (approximately 97%), minerals, organic acids and maple flavor. Starting from early March, sap will flow in the tree's body for 6 to 8 weeks, promoting the growth of the tree.
All trees produce sap, but maple trees have more and sweeter sap. The main tree species that produce maple sugar are sugar maple, red maple and silver maple.
It is said that among the 13 local maple trees, only three types - hard maple, black maple and red maple - can produce syrup.
A large maple tree can collect 4 liters of sap per day.
According to current production methods, approximately every 40 liters of sap can be made into 1 liter of maple syrup. Interestingly, according to the owner, only maple trees in North America can produce maple syrup.
As a result, maple syrup has become Canada’s world-renowned specialty. The 800-kilometer journey from Quebec to Niagara Falls is Canada's famous Maple Avenue.
Major cities such as Toronto, Kingston, Ottawa, and Montreal are all located on this Maple Avenue. The famous St. Lawrence River originates from the rippling blue Lake Ontario, parallel to Maple Avenue. More than 1,000 lakes of various sizes are scattered along Maple Avenue, thus forming lakeside, riverside and roadside areas. Maple leaves turn red in February. Beautiful landscape of flowers.
The brilliant maple leaves reflected the blue sky and clear water, dyeing the towns and villages red, making the whole place red. 4. An essay describing plants of about 200 words. There are endless mysteries in the plant kingdom. Please choose one or two to plant.
There is a mimosa in my house. I am very concerned about its growth and go to see it every day. It grows. It has green, short spikes and pink, hairy ball-like flowers, which are extremely beautiful. When you touch its leaves, it looks like a shy little girl, lowering its head and closing the leaves. You know Why? Let me tell you, there is an enlarged part called "leaf pillow" at the base of the petiole of Mimosa pudica. There are thin-walled cells in the leaf pillow. When the leaf is touched by the outside world, the vibration is transmitted to the leaf pillow. At this time, the thin-walled cells The water in the cells immediately flows to the intercellular space, thereby reducing the expansion ability of the cells. The leaves automatically close, and the petioles and twigs droop at the same time. After a few minutes of "calm", they returned to their original state. One day I came home , I found that the leaves of the mimosa were closed. I thought someone must have touched it. I stretched out my hand to touch it, but I felt my hands were cold. Oh, it’s raining! I quickly retracted my hand, closed the window, and went to do my homework. The next day, I stayed on the balcony reading a book. The sky was cloudy and ready to rain. I opened the window accidentally and found that the leaves of the mimosa were still closed. I looked up. I was surprised: I didn’t see anything touching it. How could its leaves close? At this time, it started to rain heavily, so I had to close the window and watch TV. I waited and waited, and finally waited for a rainy day. I ran home quickly, rushed to the window sill with my schoolbag on my back, ha, and One leaf did not close. I watched patiently and intently. After a while, a small insect bumped into the mimosa without thinking, and then flew away. At this moment, something wonderful happened: The mimosa leaf closed. Seeing this, I suddenly felt enlightened. I opened the book, and the book proved my conjecture. It turned out that the air humidity was high before the rain, and some bugs couldn't control themselves and hit them. Mimosa pudica, causing the closure of Mimosa leaves. I am very happy because I have unlocked the mystery of Mimosa leaves, and with this "weather forecast", I will not be caught in the rain. 5.

On the balcony of my house, there is a pot of cactus that is very inconspicuous. Cactus Its body is like a piece of emerald, and also like a cute little hedgehog. Its whole body is covered with thorns like steel needles. Don't underestimate these thorns, these are the weapons it uses to defend itself! I was stung by it, and my mother was also stung by it. It hurt so much. My mother wanted to throw it away many times, but I refused because I have a special feeling for it. I love that pot of cactus.

The Life of a Willow Tree In the past, I didn’t like willow trees very much because they were too ordinary. , there is no eye-catching place at all. In the spring of a certain year, my family and I went to a small lake together. When we were about to row a boat, we saw a willow tree with a lot of small white snow on it. Underneath, it turned out to be small white flowers. These white flowers fell in the wind and were called "catkins". I felt very poetic and fell in love with the willow tree. Wind is the most common in nature, but also the most common. Useful things. Willow trees and the wind are a perfect match. Under the blowing of the wind, the willow branches float slowly and dance with the wind; the plain lake surface, against the reflection of the willow branches, adds infinite charm. The willow tree on a sunny day , exudes the breath of sunshine, giving people a feeling of vitality; the willow trees on a cloudy day are shrouded in clouds of smoke, giving people an indescribable sense of mystery; the willow trees on a rainy day cry sadly, but do not forget Dancing with the wind. I really wish I could become a willow tree, because I admire its hard-working and uncomplaining spirit. Whenever the wind comes to it, it will fulfill its obligation and dance for the wind. Complaints. The work of the willow tree is just blowing in the wind, but it is a very noble job. Although it is used as a foil for others most of the time, it does not dislike it. What a selfless willow tree! Why is it just to be a foil for others? Cactus School: Yishi Xiaomiaoqing (Welcome your contributions to the 6-pointed star composition) The stem of the cactus I raise is flat and has many thorns growing on it. I once heard the teacher say In order to adapt to the desert climate, the leaves of the cactus become thorns, and the stems become fat and fleshy, and have many hairs. Its stems are thick because they need to store nutrients in the rainy season and reduce water evaporation in the dry season. And I I was shocked by its adaptability of "survival of the fittest". However, what shocked me even more was an incident that happened during the summer vacation. I remember that during the summer vacation, my cousin, who was four years older than me, came to visit and somehow his feet He had a sore on his palm, which made him scream in pain, and he could almost feel restless. Later, my mother found a folk remedy from an unknown book: cut the cactus into pieces, mash it, and apply it on the sore. I heard this. , shouted: “Want to cut my baby? No way! "My mother and brother made mental preparations for a long time before I agreed to cut off a piece. After a few days, the sore on my cousin's foot disappeared. I thought: "This method is quite effective, but my cactus will definitely die. "It's gone." After a few days, the "wound" of the cactus slowly dried up and healed, leaving only a white scar. At this time, I couldn't help but respect the cactus. (Welcome to contribute to the 6-pointed star composition) From then on , I love cactus even more. Whenever I see that white scar, I think of its spirit of self-sacrifice and its tenacious vitality. I secretly make up my mind to learn from cactus and be a strong person and a good person. People who are useful to society.
