I often see "piranha plants" eating people on TV. Scientists have studied many plants, but they say "There are no piranha plants in the world. They can eat people." The story of flowers eating people is also made up by people, it is just a horror movie. "But there is a plant that eats insects, it is pitcher plant.
During a holiday, my father took a bus to a Nanjing Botanical Garden. I saw many flowers in the botanical garden, including narcissus living in the water, and sunflowers following the sun... The most peculiar among them is the "nepenthes" that preys on insects. Nepenthes are made up of many leaves, and each leaf has a bright sac-shaped pocket hanging on it, which is the insect catching bag.
But how does it catch insects? It turns out that whenever insects are tired from flying, pitcher plants will release a lot of honey. In the hearts of insects, this is a food paradise. When they stop on the edge of a pitcher plant, the pitcher plant's insect trap will immediately roll up, drowning the insect. After two weeks, only its outer shell will remain.
I checked the computer, oh, that’s it! Nepenthes, like other grasses, absorbs photosynthesis and respiration every day. The roots have to absorb nutrients, but their functions are relatively poor and nutrients are insufficient, so many insects are needed to supplement nutrients.
Nepenthes are really magical! Nepenthes - Essay 350 words 2
Nepenthes is a very strange and beautiful plant. Its leaves are oval, but wider than those of Chlorophytum. There is a small leaf at the end of the leaf. The vase-like "green bag" also has some small red spots on it. It’s this magical “bag” that actually eats bugs. Although I have heard of this plant, I have never studied it carefully. With today's opportunity, I must track it down to the end!
Go to the flower market and find a place selling pitcher plants. After careful study, I found that the "bag" of Nepenthes is in the shape of a bottle, with a small top and a big bottom. There is a small lid on it that can be opened or closed. The fine hairs on the edge of the lid are stained with some honey and exude a smell. It smells sweet. As wonderful as its appearance is, its uses can be imagined.
So how do pitcher plants "eat" insects? Curious, I opened the lid a little. It was found that its bottle-shaped inner wall can secrete a juice as sweet as honey. When the bugs smell it, they will be attracted to it and drink it sweetly in the pitcher plant's bag. The pitcher plant is so cunning. When the insect was enjoying its drink, the pitcher plant closed the lid. Only then did Xiao Chong realize that he was stuck and couldn't escape even if he wanted to. In this way, the pitcher plant successfully captured a small insect.
In fact, nature is full of wonders. Many wonderful plants like pitcher plants are just waiting for us to discover! Nepenthes - Essay 350 words 3
This year, my mother bought me a pot of Nepenthes.
There are more than 70 species of pitcher plants, but there is only one species in Guangdong. It has several tender green leaves and a secret weapon - insect pods. The insect sac is cylindrical, with the lower half slightly enlarged. Because it looks like a pig cage, the whole plant is called pitcher plant. Its growth environment is suitable for a maximum temperature of 30℃ and a minimum temperature of 18℃.
How is its insect cyst "used"? It turns out that the surface of the cover above this insect sac can secrete juice to attract small insects. After an insect enters the cage, the lid will not close, but the inner surface of the cage is very smooth, which prevents the insects from escaping. After a while, the cage will secrete digestive juices, which are acidic and can quickly absorb the nutrients of the insects. Now the insects can only wait pitifully to die, which is really "hard to fly". If I could escape from this cage, I would probably be "lucky".
Nepenthes can be found all year round. Although it is not beautiful on the outside, it is beautiful on the inside.
Because its secret weapon can "catch" pests and create a beautiful environment for humans! It reminds me of peanuts, big trees, candles... Peanuts don't look good, but they are very useful: they can be eaten and squeezed for oil; the big tree looks ordinary, but it can let people enjoy the coolness and breathe fresh air. ! Candles also make people admire: they burn themselves, leaving light to others, dedicating their lives to others, and sacrificing themselves! I want to learn their dedication!
Spring is here, and thousands of households have bought pitcher plants, which symbolizes that "when a pig cage enters the water, wealth will roll in."
Nepenthes, you not only fill us with hope and bring more laughter to our family, but you also have a selfless spirit. I like you - Nepenthes! Nepenthes - Essay 350 words 4
The plant world is full of strange things. Some plants can also eat insects, and Nepenthes is one of them.
On Sunday, my mother and I went to the flower and bird market and bought a pitcher plant. The leaves of Nepenthes are long, thin and drooping, similar to spider plants. But the tip of the pitcher plant's leaves turns into a thin strip, which is the metamorphosis leaf. The abnormal leaves are always drooping, with a "little bottle" hanging underneath. The "little bottle" has a small mouth, but a swollen belly, and a small bottle cap! Nepenthes relies entirely on it to capture beneficial insects.
But how do pitcher plants capture beneficial insects? At night, I stood by quietly and waited, but no bugs flew over. I had no choice but to hang the pitcher plant on the balcony, hoping that bugs would be caught at night. The next morning, I looked into the "bottle" and saw several flying insects outside. It seems that pitcher plants can really eat insects.
But I still wanted to know how pitcher plants eat insects, so I went online to search for videos of pitcher plants eating insects. I saw a bug attracted by the scent of the pitcher plant and crawled to the "mouth of the bottle", but accidentally slipped into the "bottle". They remember running around in circles outside, running from here to there, and crawling from there to here. In the end, he was unable to struggle and died in the "bottle". In a few days, this one will be digested by the digestive juice in the "bottle" and become nutrition for the pitcher plant.
I put the pitcher plant on the balcony of my home, hoping that it would eliminate all the mosquitoes in our house. Nepenthes - Essay 350 words 5

The pitcher plant is very useful. It can eat many insects every day. Once, I saw a fly eating honey on it with relish. Suddenly, the "little lid" tilted down, and the little fly that was eating honey fell down unprepared. Then the pitcher plant began to shake desperately, Slowly it stopped. Why is this? It turns out that at first the flies were struggling desperately, but later they became the delicacies of the pitcher plants.
In order to test whether it likes to eat other things, I put wood into the mouth of the pitcher plant, but the leaves were not covered. Why? I quickly checked the computer and found that the pitcher plant Only eats carnivorous insects.

The whole body of the pitcher plant is green.
Why is there the word "cage" in its name? It turns out that a small tube grows on its leaves, like a green bird egg, with a small green lid on it, and strips of red on the lid. Pinstripes. I think that's why the pitcher plant got its name.

It kept struggling, but to no avail. After a while, the little fly stopped moving. I think this little fly must be dead. The next day, I went to see the fly again. It's gone.

People have been inspired by animals and plants and invented many things. Let me list a few for you: people invented a ship based on the appearance of a whale; an electronic nose was invented based on a puppy's nose; and a small gas detector was invented based on a fly. Look, I know a lot. I also want to invent something based on the characteristics of animals and plants.
Last Saturday, I accidentally saw a video about pitcher plants while playing on the computer. I saw a large pot of pitcher plant in a certain place. The green leaves were very beautiful. At first I thought it was just a pitcher plant, there was nothing interesting about it. People say that pitcher plants can catch mosquitoes. I also read in the composition book that pitcher plants can eat mosquitoes, but I don't believe it. Suddenly, I saw a kind of juice flowing from the body of the pitcher plant, and the little insect actually went to eat the juice for some reason. At this time, the bug was gone. I took a look and found that the bug had been eaten by a pitcher plant.
Based on this principle, I want to invent a "flying electric fly swatter". This is much more convenient than holding a fly swatter in your hand.
If you want to invent, you must study hard to become a scientist in order to invent this high-tech thing. Nepenthes - Essay 350 words 11
Today, Teacher He took a pot of a magical plant from home - Nepenthes! Suddenly the teacher became excited. Some shouted: "Nepenthes, I know it!" Some said: "What kind of flower is this? Is it a pitcher plant? How did you choose the name!"... The students all talked about it. After a while, Teacher He said: "Students, please be quiet. This flower is not for you to see in vain. Everyone should write an observation essay immediately." So I wrote this meaningful essay.
Nepenthes, also known as Cordyceps, is divided into three parts: petiole, leaves, and tendrils. The petiole is its stem, which is very thin and dark green; the leaves are grass green, some are as sharp as arrows, and some are as soft as feathers; there are insect pitchers like bottles on the tendrils, and the insect pitchers are cylindrical, with the lower part Slightly enlarged, there is a flat bottle cap on the cage mouth with small whiskers on it. The pitcher is a unique organ of Nepenthes that absorbs nutrients.
The function of pitcher plants is not only to decorate the home, but also has a greater function of catching insects. First, it creates a sticky honey juice at the bottom of the bottle to attract insects, and then guides the insects to the bottle cap. The bottle cap is very smooth. When the insects fall on the bottle cap, the bottle cap slides to the bottom of the bottle and sticks to it with mucus. Don't move, then tightly cover the bottle cap. After a while, the insects will turn into sap, and the pitcher plant thrives by absorbing the nutrients of their sap. Ha ha! Isn't this a "waiting for the rabbit" approach to preying? Interesting.
Nepenthes not only looks beautiful, it can also help us eliminate pests. It is really a good helper for us humans! I love this amazing pitcher plant! Nepenthes - 350 words essay 12

Nepenthes can prey on various insects, but it has very high requirements. If the temperature is below 20 degrees Celsius, it cannot grow.
I am particularly interested in pitcher plants, so my mother helped me plant a pot of pitcher plants.

It smelled the fragrance of honey, and involuntarily flew to the place where the fragrance was emitted - the pitcher plant. In the "bottle". As soon as it flew in, the "lid" closed. As soon as it flew in, the "lid" suddenly closed. It struggled desperately, but the inner wall of the pitcher plant was very smooth. No matter how hard the mosquito struggled, it could not escape and could only be digested by the pitcher plant.
"I haven't watered the pitcher plant for several days. I don't know how it is doing." I hurriedly watered the pitcher plant. I saw that its stem was bent and weak.

I didn't expect that the little pitcher plant has so many mysteries. In the future, I will explore these little secrets and make them more interesting. Let me introduce to everyone. Nepenthes - Essay 350 words 14
There is a pot of Nepenthes that my mother bought from the flower and bird market on the balcony of my house. It has been in our house for over a year.
Nepenthes is a vine. The stem is hard and thick, almost as thick as our thumb.
The leaves of Nepenthes are oblong, some are dark green, and some are light green. The leaves look as if they have been waxed, very smooth, and will emit an oily sheen in the sun. There is a red and long vine on the top of the leaves connecting the insect pitchers.
The most interesting thing is its insect trap. It looks like a vase with a big belly, and also looks like a pig cage common in the countryside. The largest part of the insect pitcher is the pitcher body, which is green with reddish appearance. The pitchers become thinner and thinner from the shoulders upward, and the color becomes redder and redder. Its cage mouth is sloping and has a round lid.
The inside of the insect trap will emit a smell that insects like. When the little bugs smell it, they will rush to fly to the pitcher plants. A little bug flew into the cage mouth and wanted to stand on the cage wall. The cage walls are very smooth. As soon as the little bug stood up, it was like riding a roller coaster, and fell into the digestive juice with a "squeak". When the cage lid was opened again, the little bugs were gone and turned into juice.

Nepenthes is like a honey jar. There is a layer of honey at the "mouth". If some greedy bugs come to eat the honey, they will slide down. No matter how hard these bugs try, they will not be able to eat it. Want to climb up. When the bug gives up the idea of ????escape, its surroundings will heat up, and after a while, it will be digested. So there are almost no mosquitoes bothering us in summer because they are all eaten by the pitcher plants as delicacies.
The density of pitcher plants not only attracts small insects, but also attracts the greedy me!
That day, my mother was not at home. I ran into the room, locked the door, ran to the pitcher plant, dipped some honey in my fingers, and put it in my mouth. "Oh, it's delicious!" I felt happy in my heart. "No wonder those bugs come to eat them!"
Nepenthes also has a lid, which is divided into three colors: red, yellow and green. It also glows slightly at night. From a distance, it looks like a shining star. Its root is as thin as a grass bud, but it is very long, like an old man's hand. Nepenthes has no leaves.
Nepenthes can drink water very well. Water it three times a day, and you need about a cup of water each time. Well, the good thing is that it doesn't require fertilizer.
