Nepenthes fourth grade composition
In real life or work and study, everyone has dealt with writing. Through writing, we can gather our scattered thoughts together. So how to write a general composition? The following is my fourth-grade composition of Nepenthes, which is for reference only and I hope it will help everyone.

Nepenthes fourth grade composition 1 My family has a pot of Nepenthes, which was given by a friend of my mother.

I hung this pitcher plant on the railing of the balcony and began to observe it carefully.

Nepenthes leaves are very long and special. It has neither petioles nor veins. The first half is big and the second half is small, just like a fan.

The most interesting thing is that the tip of each leaf ejects a line as thick as rice flour, which is connected with a long bottle-shaped thing, which is the so-called "pig cage". I think Nepenthes probably got its name from this. In fact, it is not so much a bottle as a pig cage. The most amazing thing is that the thick line at the tip of the blade is connected to the bottom of the "bottle". The bottle is upright and the mouth of the bottle is always facing up, as if it were folded and fixed there.

More than twenty bottles, large and small, can be hung on a pitcher plant. These bottles are red and blue. They have big bellies. There is also a bottle mouth on the bottle, which feels a little rough. There is a small leaf on the bottle mouth, which is its bottle cap. There is still a lot of water in the bottle. What kind of water is this? I didn't know until I checked the information. This is its digestive juice.

Nepenthes is an insect-eating plant. There is honey on the side of its lid. Insects flew to the lid to eat honey, immediately slipped into the bottle and were digested in a short time.

This pitcher plant is beautiful and interesting. With it, I am not afraid of being bitten by mosquitoes anymore, because it can eat mosquitoes.

Today, my mother bought a pot of pitcher plants. I shouted, "Mom, why did you buy this?" Mom smiled and said, "Control bugs, and let you keep an observation diary by the way." "So, I wrote this composition.

Nepenthes, also known as Cordyceps, is divided into three parts: petiole, leaf and tendril. Petiole is its stem, very thin and dark green; Leaves are grass green, some are as sharp as arrows, and some are as soft as feathers; Tendrils are like a bottle-shaped insect trap. The insect trap is cylindrical with a slightly larger lower part. There is a flat bottle cap with a small beard on it. Insect trap is a unique organ for pitcher plants to absorb nutrients.

The function of Nepenthes is not only to decorate houses, but also to catch insects. First, it makes a sticky honey juice at the bottom of the bottle to attract insects, and then leads the insects to the bottle cap. The bottle cap is smooth. When the bug landed on the bottle cap, it slipped to the bottom of the bottle and stuck with mucus. Then they closed the bottle cap tightly. After a while, the insects turned into juice. Nepenthes thrive by absorbing nutrients from their juices. Ha ha! Isn't this the way of "waiting for the rabbit"? Very interesting.

Nepenthes is not only beautiful in appearance, but also helps us to eliminate pests. It's really a good helper for us humans! I like this magical pitcher plant!

Nepenthes is different from other plants This is an insect-eating plant. Other plants are eaten by animals, but pitcher plants eat insects.

Nepenthes looks like a long lantern with a green top and a red bottom. There is a leaf on it, like a small lid. There is some honey on the leaves. There is also honey on the bottle mouth of Nepenthes, but it is more than the leaves on it. Nepenthes is smooth inside and there is some liquid under it.

How does Nepenthes catch insects? Let me tell you something! The honey in the mouth of Nepenthes leaves will give off fragrance, and insects will fly over. Before it eats honey, the insects will fall down because they are unstable and fall into those liquids. At this time, the leaves of Nepenthes will be covered, and when the leaves are opened again, the insects will have decomposed. In addition, it is worth mentioning that the leaves of Nepenthes do not carry out photosynthesis, and the leaves are just decorations. And Nepenthes, there is a kind of spider in it. It has lived in Nepenthes for several generations, and he also wants to survive in Nepenthes. It crawls in the pitcher plant by silk, and will eat some fallen insects first, and then give them to the pitcher plant. If you are not careful, it will become Chinese food in pitcher plants.

Nepenthes is really an interesting insect-eating plant.

When reading Nepenthes written by Shen, I thought Nepenthes caught mosquitoes and flies and was a carnivore in plants. The leaves of this grass are oval, and the end of each leaf becomes longer and thicker, forming an insect trap, with the mouth facing up and a cover. When you grow up, the lid won't be closed again after you open it. This cage is like a pigsty but grass, so it is called Nepenthes.

How does Nepenthes catch prey? Please look at the red-lipped killer in the encyclopedia-Nepenthes. This kind of grass has a nectary on its stem, leaves and cover, which can secrete honey drops, which is the favorite smell of insects. This smell attracts them to the lid. This lid contains not only honey juice, but also anesthetic, which is a fatal trap. After smoking, the bugs staggered around the trap like they were drunk. Because the bottle is smooth inward and barbed upward, the liquid in the bottle is an acidic digestive juice. After the insects are digested, they will be converted into their own nutrients and absorbed. This is really the last supper for insects!

I think this pigsty is really an elaborate trap! Our society is also a world full of temptation. Let's keep our eyes open. Don't take things that don't belong to you, don't look at things that shouldn't be seen, and don't go places that shouldn't be. One short step makes a long regret, and there is no regret for selling medicine-so we should enhance our safety awareness and learn to protect ourselves.

Nepenthes fourth grade composition 5 Today, I found that there are many changes in Nepenthes at home.

This pitcher plant was bought by my mother after visiting Wuhan Botanical Garden with relatives from other places. In fact, this pitcher plant was bought in June+10 this year. There is only one pitcher plant now, and there are more and more pitcher plants, and there are already ten. In summer, there are few flies and mosquitoes around my home. This pitcher plant has become a very important member of our family.

Every time I come home from school, I observe it, but I rarely find that pitcher plants have changed. Usually my parents tell me. Finally, in June 10, I finally found out for the first time how pitcher plants eat insects. I deliberately opened the door to let some flies fly in, but their purpose was not to suck our blood, but to fly to Nepenthes. I'm a little confused. At this time, this one stood on the pitcher plant and has been wandering there. However, as soon as I turned around, the fly disappeared inexplicably. I turned on the computer and looked it up. The answer is at hand. It turns out that Nepenthes will give off a smell that pests like, attracting pests to let them in. After a second, the mouth will close, and after a few minutes, the pests will disappear.

I admire my pitcher plant very much. It's really a "master insect catcher"!

Nepenthes fourth grade composition 6 There is a big garden in front of my house, which is planted with all kinds of beautiful flowers and plants. Every time I finish my homework, I go to the big garden to enjoy it.

The afternoon before yesterday, I went to the big garden to enjoy flowers as usual. Suddenly, I found a red and green plant in the corner, with wide and big leaves and a cage-shaped bottle hanging on the leaves. There is a lid on the bottle. I felt very novel, so I ran to the house and asked my father who was reading a book, "Dad, I don't know when a red and green plant will appear in the corner of the big garden." As he spoke, he dragged his father to the big garden. Dad looked at it and smiled and said to me, "This plant is called Nepenthes. It can catch insects in a cage with leaves." I was even more surprised and said, "Insect hunting?" "Yes, you don't believe it, do you? Then why don't you observe? " After listening to my father's words, I started my own action.

I sat by the garden with curiosity and waited quietly. After a while, a mosquito flew over and landed on the lid. After a while, the mosquito slipped into the bottle. Curiously, I opened the lid and saw that mosquitoes were stuck with sticky juice and could not move. It turns out that mosquitoes, ants, flies and so on. After a while, it becomes juice, and pitcher plants grow up by absorbing their juice.

Ha ha!

This is the first time I have seen this kind of plant "waiting for the rabbit" predation!

I like bright roses, shy mimosa, flaming roses … but I prefer interesting Nepenthes.

Today, the Chinese teacher showed the students a pot of pitcher plants.

The stem of Nepenthes is green, and there are many leaves of different sizes on it. The big leaf is green, like a rabbit's ear, and the small leaf is light green, like a twisted wire.

Looking down the veins, you will find a vine with reddish green. There is a vase-like pigsty at the bottom of the vine and a "teapot mouth" at the top of the pigsty with a lot of sweet honey on it. As soon as greedy bugs fly to the "teapot mouth" to eat honey, they will "purr" into the "vase" and become delicious pitcher plants. The most interesting thing is that the naughty Zhong Zihao put his finger into the "vase" so that Nepenthes wouldn't let him into his territory! Zhong Zihao's finger was scalded and he cried out in pain: "Pain, pain!" " "

I have only seen animals eat plants, not plants eat animals. I have only seen this interesting plant-Nepenthes.

Nepenthes fourth grade composition 8 Maybe you have read horror novels about man-eating plants, and the mutant plants in horror movies make you tremble with fear. In fact, there are no plants that can eat people, only plants that can eat insects. This may be the carnivorous plant mentioned on TV, right? Last year, I was lucky enough to see one of the plants-Nepenthes.

One weekend, my father said happily, "haven't you always wanted to see what carnivorous plants look like?" The car is downstairs. do you want to see it ? "I replied," go! After a while, the car drove to Jiangtun District, the largest flower town in Tengzhou City (I forgot the specific name! Haha srrog). I walked quickly to the indoor tent, when I found that there were no mosquitoes and flies in the sultry tent. I noticed pitcher plants hanging in the air. Its shape is very strange. Like other plants, it has some symmetrical and broad leaves. From the root of the leaves, it extends a "poison pot" and people give it magical colors. I reached into many places where small insects lost their lives with curiosity, dad. Then I pulled my finger out of my pocket. Hey! it doesn't matter

After this incident, I dispelled my fear of pitcher plants.

Nepenthes fourth grade composition 9 Today the weather is excellent and sunny. My mother and I went to the new flower and bird market to play. Mom said she would take me to see the magical pitcher plants. We searched there for a long time before we found the real Nepenthes. Mom said that Nepenthes can eat worms, but I don't believe it. How can it eat worms without teeth and hands?

Nepenthes leaves are green, long, sharp and flat, like a boat. Its flower is a pot with a big belly. The spout is upward, smooth, and there is a leaf like a small lid at the spout. I saw some liquid at the bottom of the pot, which gave off a special fragrance.

After waiting for a long time, I saw that a bug might smell the fragrance and crawl around the jar mouth slowly. Because the liquid is at the bottom of the jar, it tries to look at the bottom of the jar. Because the jar mouth was too slippery, it accidentally fell down. At this time, a magical scene happened. The small leaves at the jar mouth quickly covered the jar mouth and became a tight lid. After a long time, the small lid slowly fell down again. The worm was eaten! This is really amazing!

Nepenthes fourth grade composition 10 Speaking of Nepenthes, some children's shoes will definitely think? Nepenthes, pig cages or grass? Yes, Nepenthes got its name because it looks like a pig cage.

Nepenthes is a tropical insect-eating plant, also known as Leigong pot. Nepenthes has a unique insect catching organ-insect catching cage. The insect-catching cage is cylindrical, the lower part is slightly enlarged, and the cage mouth is covered. There is mucus on the edge of the cylindrical insect trap, which can emit fragrance and attract small insects. When a little Kun sticks to the liquid at the edge, the cage cover will touch and the little insect will fall into the cage. Cage plum can secrete a liquid to digest small insects. After digestion, the cage cover will automatically reopen, waiting for the arrival of the next small insect.

I want to invent a mosquito trap with pitcher plants as raw materials, which is similar to pitcher plants, except that the edge of the mosquito trap emits a bloody smell that humans can't smell but mosquitoes can smell, and there is a mosquito trap grid at the lower part. When mosquitoes fly on the edge, the sensed cover will close quickly and quietly. Mosquitoes fell in. At this time, the power grid is induced and the power generation mode is turned on. The rhythm of the net is the same as that of mosquitoes. Mosquitoes were electrified to ashes and fell under the power grid. At this time, the cover automatically opens again, waiting for the arrival of the next mosquito.

The next day, all you have to do is screw out the lower part of the power grid and throw away the mosquitoes that have turned to ashes.

Do you really want one? Let's study hard and invent it in the future.
