Discover the secret ingredients of plants

Once I discovered the secret composition of plants and saw a lot of grass growing on the roof of my house. I felt very strange: "Hey, why is there grass growing on the wall?" I was confused and vowed to make it clear.

I hurried home and asked my mother who was cooking. My mom said she didn't know either. I looked up information everywhere with curiosity. However, after searching, I finally found nothing ... One day on Saturday, I finished my homework and squatted in front of the door staring at the grass on the roof. Suddenly I saw a hungry bird eating rotten tomatoes, only to see its small and exquisite mouth covered with tomato seeds. I meditated and thought of the grass on the wall. Could it be a bird's "masterpiece"?

It turns out that there are many ways for plants to spread seeds, one of which is animal transmission. Birds and other animals fly around freely after eating these seed plants, and accidentally fall on the wall to rest, and as a result, they will leave the seeds in their mouths on the wall. If there is enough sunshine, such as rain, grass will grow on the wall before long.

This little thing tells me a great inspiration: as long as you observe things around you with your heart, you will certainly find something and gain something!

Find the secret of plants 2. There are many kinds of plants, which look strange and have their own characteristics. For example, Xanthium sibiricum is full of armor, the purple shirt is grotesque, the blood is highly toxic, and the palm trees are tall and thick ... As long as we observe carefully, we will find the mystery of plants.

Today, I observed a xanthium sibiricum. From the outside, I can't see anything. However, a closer look reveals that there are many small Mao Mao on the stem. Look at the fruit of Xanthium sibiricum again. Squeeze it flat and it will swell up again later. Cut, see obvious lines, peel off this layer of skin, there are black embryos inside, and then peel off another layer of skin, which is another layer of black embryos. There are three layers in Xanthium sibiricum, which I never knew.

Also, picking a leaf is nothing special on the surface, but have you ever thought about cutting it? If you look closely with a magnifying glass, you will find that there are many small holes that are almost invisible to the naked eye.

People know little about the secrets of plants. Plants still have many secrets of their own, waiting for human intervention and uncovering.

Discover the secrets of plants. There are many secrets around us. Let's find the answer. I'm talking about sunflowers now.

Sunflowers can be seen everywhere around us. Yellow petals, red stamens, one or two green leaves, so cute.

One day, I found it open in a bright sunshine, but if you take away its sunshine with a paper tape, it will close slowly and bit by bit, but when you give it back the sunshine, it will open again. What's going on here?

I looked it up on the Internet, only to know that this flower is called sunflower, where there is sunshine, it will open slowly, and where there is no sunshine, it will never open. I heard someone say that a man had done an experiment. He bought two identical sunflowers, one in the sun and the other in the field without any sunshine. After a while, the pot placed in the sun was full of flowers, but the other pot still didn't open a flower.

From this incident, I learned that the secrets of nature are interesting. So we need to know more about extracurricular knowledge.

Everyone has a pair of eyes that are good at discovering plants. Today, I want to share the secret I found.

When I was a child, I felt very hot every time I played and chatted with my friends in the hot sun, and then I looked around to see if there was any place to enjoy the cool. So, in the village where grandma lives, the big banyan tree at the end of the village has become my favorite place to go in summer.

Once, my friends and I enjoyed the cool under a big banyan tree. Suddenly, a child asked us, "Why can this big tree stand out like a general in the scorching sun?" The little flower and grass next to her looked very listless with her head down. "We also felt very strange and went home with this question.

After that, I asked a lot of people, but there was no answer. Just when I was disappointed, an accident made me feel a glimmer of hope. It was an ordinary science class. In class, the teacher said something about plants. I heard an answer: "Because it is very hot at noon, the soil will be very hot, so the plants are fine in the morning and bow their heads at noon." When I heard this knowledge, I thought: I must stick to it and solve that problem!

Then I asked my learned cousin. He told me: "Because there is water in the branches of the big banyan tree, it will be very energetic at noon."

I finally solved this problem and let me know the secret of a plant.

Looking for the secrets of plants 5. My home is full of green plants. Among many green plants, "interesting" is red.

For Zhu Dinghong, whose scientific name is red, its stem is quite different from other plants. Its stem is similar to gladiolus, and it is a slender and tall leaf. However, don't think that it is just an "enlarged grass" with no advantages. Its vitality is extremely tenacious, which is one of the reasons why I call it "the king". Tear off a leaf with a ball from the mother and press it in the soil casually. As long as there is enough water and sunshine, it will grow into an independent and vital mangrove in a few weeks.

Besides, its flowers are unparalleled. Its flowers are as bright red as pomegranate flowers; The flower is shaped like a lily, and its petals are like an upside-down dress. The flowers are elegant and generous. Red always blooms in pairs: 2, 4 ... Before flowering, it will gather all the energy and quickly grow a stout flower stem with pairs of buds on it. My flower counter always blooms four at a time, like a road sign, showing its delicate flowers in the east, south, west and north directions respectively.

There is another secret about Hong, which I discovered by accident.

Once I went home and sat in a chair because I didn't do well in the school exam. I looked up and saw a pair of blooming red flowers. Its bonus is so shiny, but the more I look at it, the more dazzling I feel, and my mind is blank. I wanted to uproot it, but as soon as I pulled it out, I realized that I had committed the old habit of sabotage and was going to be criticized again. "What should I do? What should I do? " I ran around like a headless fly for fear that my mother would find me. Finally, I decided to bury it in the ground again. I was naughty again when I was ready to plant. I planted it upside down to see if it was still alive.

One day, two days ... under my careful care, it finally took root again. I carefully observed that its roots were trying to penetrate into the soil. No matter how many sticks I put up to stop it, it still struggled to put its roots into the soil and its leaves tried to stretch upwards.

I was puzzled, so I looked for "100,000 Why" to find the answer. It turns out that gravity is at work.

Through this observation, I discovered the secret of the plant kingdom, that is, the influence of gravity on their growth.

There are many mysteries in nature that attract people to discover. One day, I came across the secret of a plant-the secret of mimosa.

Every day at noon, some weeds I don't know will stand by the roadside and greet me. One day, when I was walking, I accidentally stepped on a plant. When I was lying on the ground, the plant actually shrank quietly. I feel strange, how can plants move by themselves like people? In order to see what this guy really is, I squatted down and touched it with my hand. This guy has shrunk again. At this time, a sentence that my teacher said in the third grade appeared in my mind: "There is a strange plant in life, that is, mimosa." Just touch it and it will automatically shrink. " What the teacher said is exactly the same as it is now. Is it a mimosa? But my other question comes again: why does it shrink when touched lightly? Are you really as shy as human beings and afraid of meeting people, so you shrink back?

I don't know if the answer is right, so I asked my teacher. The teacher told me happily that mimosa is shy because every leaf has a "swelling-reducing effect". At the bottom of the petiole of mimosa, there is a very swollen parenchyma called leaf pillow, which is full of water. When you gently touch the leaves of mimosa with your hand, the leaves begin to vibrate, and the water under the pillow will flow in all directions. At this time, the pillow will contract, the upper part will bulge, and the petiole will droop and close.

Since I discovered the secret of mimosa, I understand that there are still many unknown things in nature waiting for us to discover. As long as we have a pair of eyes that are good at discovering, you will find many beautiful things in the world.

It was a summer day. In the afternoon, I was playing in the yard and suddenly found some yellow leaves on a row of trees next to the yard. I was curious, so I went up to him gently and took a look. Who knows, just when I was about to touch these leaves, the "dead leaves" actually flew away!

When I got home, I told my mother this strange thing. My mother smiled, squatted down and touched my hair and said, "honey, it's not dead leaves that fly away." It is called dead leaf butterfly, which belongs to a kind of butterfly. Its wings are like dead leaves, which can protect itself in danger. Do you understand, son? " I listened and nodded in confusion.

The next day, I saw some dead-leaf butterflies in the Woods. After careful observation, I found a small dumpling near it. I squatted on one side carefully, observing the change of this jiaozi. Soon, a caterpillar came out of the jiaozi ... I ran home and asked my mother what was going on. My mother said, "that's the baby of the butterfly." When it is a larva, it will become a pupa. Usually it takes five to ten days for a pupa to emerge into a butterfly. " This time, I nodded and said, "I know, mom."

This discovery inspired me: as long as we are good at observing, there will be many discoveries in life.

One day, my father brought back a pot of green plants with palm-shaped leaves. I asked curiously, "Dad, what's this called?" Dad said, "figs." I asked again, "Why is it called fig?" Dad replied, "Because it bears fruit without flowering."

My father's answer puzzled me, and my curiosity drove me to observe the fig. After a few days, I was surprised to find that it had produced a small green oval fruit. But I really didn't see it blossom. Can it really bear fruit without flowering?

I look left and right, and then I poke a leaf with my hand and look for it carefully. I looked for it for a long time, but I still couldn't find it. "Why don't figs have flowers?" I asked my father puzzled. Dad replied, "I don't know." Since my father didn't know the answer, I decided to find out for myself, so I looked it up online.

After a long search, I finally found that the green "fruit" I saw was not the fruit of fig. It was called the "general socket" and the "general receptacle" with a deep depression at the top, which wrapped the pistils and stamens tightly, leaving only a small hole for pollinators. It looks like the fruit of other plants. We eat figs, not real figs, but meatballs with swollen receptacle. Its real fruit is hidden in meatballs.

I finally know the secret of fig! I excitedly told my father the result, and my father was proud of me. This incident made me understand a truth: the mystery of nature is endless. As long as I explore carefully, I will uncover more secrets!
