My new discovery, plantary. Thank you

Today, I saw the endless desert on TV. Suddenly I saw a few cacti, and two questions came to my mind: 1, the cactus asked what can survive in the desert, 2, what is the function of the cactus's thorns.

I ran over to my dad and he said, "You can find out for yourself." So I bought a cactus and observed it myself for 10 days, but I still didn't find anything. Mom came up and said, "Why don't you look up the books?" "This proposal struck me. ”

I found the encyclopedia, oh it turned out that the cactus asked what can survive in the desert because the climate in the desert is hot and the rain is scarce. The temperature difference between day and night is large, and many plants cannot grow here. The reason why the cactus can survive in the desert is that its roots are very deep in the sand, which absorbs water, and second, its stalks become fleshy and can store a lot of water.

The third is to degenerate the leaves into needles to reduce water evaporation, so they can survive in the desert.

What does the cactus spine do because the cactus thorn is a degraded cactus leaf, it protects the plant from being eaten by herbivores, and it also absorbs water from the air, and if it rains, it can also absorb rain constantly.

I've learned that as long as you use your brain, you can solve problems, and you can't look up books.

This essay is not good at all, I will give you a zero point, 0:00 points

Why don't ants get lost?

Ants, I believe everyone is familiar with them. So who can really understand ants? Why don't ants get lost?

With this question in mind, I consulted some books. The book says that after the ants depart from the anthill and arrive at their destination, they will leave some smell along the way and return to the anthill. Touch each other with your antennae to notify the other ants.

Scientists have conducted an experiment on this issue. Scientists first identified an ant and vigorously wiped it clean along the way to its destination. When the ant returned, it suddenly stopped where the smell had been wiped off.

I was looking for something while going around in circles. Thus it is concluded that ants rely on smell to discern the direction.

To confirm this conclusion, I did an experiment. I first prepared a small branch of about 10 centimeters, and put a bait at one end of the branch - a small candy. I put this device near an anthill.

After a while, an ant came out to explore the way. After I led him to the stick, he reached the place where the candy was, as if he were sniffing and sniffing. I took the opportunity to cut off the broken part of the stick by one centimeter.

When the ant returned, it turned left and right in the place where it was intercepted, but it couldn't find its way home.

After a while, I repeated the above test again, and the ants still haven't found their way home.

Through these two experiments, I finally learned the secret of why ants don't get lost. It turns out that ants discern directions based on smell.

There is a ray of sunlight shining through the morning mist. Women's Day is coming quietly. I quietly got up, picked up the money under my pillow, and walked out of the house lightly, for fear of alarming my sleeping mother.

I ran into the flower shop in the bright morning sun, looked at the carnations still glittering with dew on the petals, and bought a bouquet without hesitation. On the red and yellow petals, the dew was whirling mischievously, rolling like pearls, shining with a charming light. I think:

Mom would be very happy to see this flower.

I rushed home with the flowers, held the bouquet in my hand, and stood there waiting for my mother to wake up, and after a while, there was movement in the house, and it was my mother who got up. When she opened the door with a "squeak", I immediately offered the carnation with both hands, and my heart was like a little rabbit thumping, and I said shyly and intimately: "Mom, I love you!"

Happy holidays! "Mom was stunned by my sudden move. He was stunned, and then looked at me with those kind eyes for a long time, speechless.

I thought: Mom forgot her holiday! I hurriedly said:

Mom, Happy March 8th Festival! A word woke up the dreamer, and my mother immediately opened her mouth. She looked at the delicate and lovely carnation, and then at me, who was sweating profusely.

took the flower, took me into his arms, and said with relief: "Child, you have really grown up, and your mother loves you." Mom's voice trembled, and her eyes were already glistening with tears.

A ray of sunlight shone in and shone on my mother's dry hand. So, what kind of hands are they! The wrinkles are like spider webs, not as soft and white as before, but as abrupt as the veins and veins, like the dry old bark.

That's because these hands toiled day and night, never stopping. How many days she used these hands to wash and cook, and wash the vegetables; How many sleepless nights she threaded the needle for me with these hands. 12 years have been like a day, a pair of satin-like hands have changed, all changed.

Day after day, I went through hard work to shape me into an innocent big child and create a warm and happy home for me. My mother's nurturing kindness to me should not be reciprocated, and my small "I love you" is nothing; I made my mom happy once and it was nothing. Even if my mother is so happy every day, it is just a cluster of waves in the vast sea, a basin of clear water in the Yangtze River, and a leaf in the dense forest!

Yes! Mother's love is like a big umbrella that covers the sky and the sun, sheltering me from the wind and rain; Mother's love is like a ray of sunshine, warming my little heart; Mother's love is like a spring breeze, gently soothing the wounds in my heart.

My friends and I were playing on the lawn when we spotted a colony of ants moving, and the sight caught our attention. At this point, a question came to my mind: why did they move?

My curiosity led me to follow them to a small slope where they were digging holes in the dirt. It took a while to dig for a new home. After making a new home, the ants go in.

At this time, a drop of rain fell on my head. Ah, it's raining! We hurried back to our homes.

At this time, a question came to my mind: why does it rain when ants move?

By consulting the encyclopedia, I understood that before the rain, due to the low air pressure, the air has more moisture, and the weather is more sultry, and after the ants feel it, they feel that their homes are prone to flooding due to the low terrain. If you move your home to higher ground, you won't be flooded. Oh, I see, it turns out that ants can sense changes in the weather and are experts in weather forecasting!

Through this discovery, I have learned a truth: we should explore more in nature, because there are still many things we don't know in nature waiting for us to explore, as long as we observe carefully, there will definitely be more new discoveries.

One: Don't reply to me one by one and say your name: Won't you see you again? Everything I'm here is the same, it's a bit of a funny thing, my life is a person's way of life, a person's way of life, and a really good way of life.

"62616964757a686964616fe58685e5aeb931333365646237 Dangdang! A crisp slap on the table came to my ears clearly.

My mother's hair seemed to stand on end, but she had to soften her voice and say to me, "Daughter, why do you have so many winter vacation homework that is not up to standard?" ”

I glanced at the pile of homework with my eyes, and indeed, many of them had big question marks, even bright red crosses. I panicked, but I stiffened my neck, stood up from my seat, and retorted in a tough tone: "What's wrong, what's wrong!"

If you don't work hard, you can't do it! Mom, why do you bother to pursue this little thing! ”

My mother said to me in a serious tone, "What is next time!" Next time if you're still like this, think about it! ”

Accompanied by my mother's words, I fell into memories.

For six or seven days of winter break, I played like crazy and didn't even think about homework. My mom told me to do more homework and hurry up. But I don't think so:

As a result, to my surprise, because I couldn't buy a ticket, we had to postpone our return to Hangzhou for two days, and when I left the journal for only six days, I was still in Nanjing, and I began to be anxious, like ants on a hot pot, fidgeting: "What should I do?" There is definitely not enough time, and it is doomed!

Even my mother said that, and I was so depressed that I was desperate.

Although I did all my homework before the start of school, those four days were very intense, doing it during the day and at night, and most of the time I was at my desk. I regret that in my heart!

"Do the important and must-do things first" and "do the right things at the right time", I understand the principles of rational time arrangement. But when I thought back to the whole thing, I found that if I had done more homework earlier, and not put things at the end of the restriction period, I would not have been in a hurry at the end; If you don't rush the job nervously, the quality will be greatly improved.

Because there may be other circumstances that affect the original arrangement, I have to learn this lesson and get things done early to give myself leeway.

Today, I made a big discovery.

It's so hot today, it's like a steamer in the room, and I'm sweating profusely. I'm a big fat person, and it's inevitable that I'm afraid of the heat. I was afraid that I would be steamed, so I quickly turned on the fan, and the wind was too strong in second gear, and too small in first gear.

I'm always not satisfied. Finally, I picked up the fan and slapped myself. Suddenly, the electric fan was shaken by something, and it also spun up.

I wondered, what is causing the electric fan to spin? Is it the fan in my hand?

I was ecstatic at what I found, so I took the fan and fanned it a few more times, and the fan shook a little. And the fan blades also turned a little. So I fanned the fan a little harder, and aha, the fan spun a little faster.

I yelled "whoa" excitedly, which attracted my dad to him, and he said, "What are you doing?" I said, "I didn't turn on this fan, it turned on."

Dad shook his head and pouted, don't believe it? I repeated the trick I had just done, and my father was convinced: "Yes, another Watt Newton is about to be born."

By this time I was already sweating a lot, but for my new discovery, I was happy to bleed, a little sweat is nothing!

So I increased the intensity and continued to fan, and the fan turned faster and faster. I danced with the fan like a madman. In a few moments, the fan was spinning as fast as first gear.

I hurriedly called my mother over. "Mom, believe it or not, I don't turn on the fan, but the fan can also turn? "Mom walked over a few steps, I demonstrated it again, and my mother praised it repeatedly:

Uh-huh, yes, my baby has shown mom a long time. ”

I know how the fan spins, but it's the first time I've known how I can spin the fan by hand.

I discovered the secret of the cactus On Sunday, I was at home admiring the cacti raised by my father. Suddenly, I discovered that cacti, cactus, cactus whip and other cacti have a common feature, that is, the flesh of the stem is thick, green in color, and the stem is full of spikes. I asked Dad:

Why do cacti grow like this? "Because cacti are native to Latin America and evolved to survive in arid and water-scarce deserts, they are constructed to be highly drought-resistant," Dad said.

I looked left and right, curiously admiring this particular flower. Why do cacti have no leaves, only prickly thorns? If there are no leaves, how can it absorb and transport nutrients?

How did they survive so well?

I looked closely and looked for relevant information, and finally discovered a secret. It turns out that the thorns on the cactus are made of leaves. Because the cactus lives in the desert for a long time, where it is hot and dry, if it produces large leaves, a lot of water will evaporate from the leaves.

As a result, the leaves of the cactus become thorns, and the fleshy stems store a sticky slurry that absorbs and retains water in the body. Ah, the thorns on the cactus turned out to be leaves! I finally understood that the flesh of the cactus is thick and prickly, which is the result of adapting to the arid environment.

In addition, my father told me that the large area of thorns in the cactus not only reduces water loss, but also makes other animals dare not harm it. I didn't believe it, so I gently touched the thorn of the cactus with my hand, it really hurt! No wonder people don't dare touch it.

Cacti are so smart. In order for itself to survive, it knows how to change itself flexibly.

I believe that everyone has their own hobbies, and my hobby is reading supermarket advertisements.

I especially like to watch supermarket ads. Once, I was watching an advertisement, "Fried chicken is six yuan, meat floss toast is yuan, clever and soft, wow, only three yuan." Usually it costs 6 or 7 yuan.

It's a lot of fun. I'm looking at it. My grandmother called me to eat, and I brought the advertisement to the dinner table, and it happened to be a fish on this day, and my grandmother thought it was a fish bone.

I spit out a few fish bones on it, and I cried loudly, you compensate me. Good, good, good. I'll compensate you, okay?

That's pretty much it.

Isn't my hobby weird? I love my hobby.
