A little knowledge about seed growth

1.50 words describe the growth of small seeds.

Whew, the wind blew a small seed into the shadow of a big wall.

Ouch! The little seed cried sadly. Why is the little seed crying? Because it sends out thin and small buds, because it grows thin and small, the surrounding flowers and trees often laugh at it. The little bee heard its cry and said, "Little seed, why are you crying?" The little seed said, "I am thin and small because the big wall blocks the sun." The little bee said, "So that's it! Then I will help you tear down the big wall. " The little bee used up all her strength, but the wall did not move, so the little bee had to fly away with a sigh. The little snail saw the little bee fly away and said to the little seed, "Little seed, you climbed to the wall with your hands and feet like me!" " Little seed, your thin vines are your hands and feet! "

The little seed heard what the little snail said and bravely climbed to the top of the wall. Finally, the little seed climbed to the top of the big wall.

In the golden sunshine, the green leaves are holding yellow flowers, which is very beautiful.

2. A brief description of the story of the growth of small seeds

I am a small seed, and my hard shell protects my weak body. I am the seed of Chinese rose, which was bought home by my master.

I was planted in a flowerpot with beautiful lace. My master gently covered me with soil, then slowly leveled it, poured water on it and put me in a sunny place. Ah! It's really dark in the flowerpot! After a while, I felt hot and dry all over, really uncomfortable! I am suffocating. It turns out that it is noon now, and the sun shines on the soil, which makes me have this phenomenon. Fortunately, after a while, the sunshine was not so strong, and I was no longer uncomfortable. How time flies! I felt so sleepy that I fell asleep unconsciously …

Early in the morning, I was awakened by the sound of running water, and my master came to water me again! I am constantly sucking delicious water, which is really comfortable. In this way, I live a repetitive and monotonous life every day. However, suddenly one day, I found something growing on my head, which was very uncomfortable. Come to think of it, have I sprouted? I am willing to stretch hard, but the soil is too hard for me to stretch. At the right moment, the master watered me again and loosened the soil for me. I stuck my head out with joy. Ah! Finally see the sun, the air is so fresh! This is much better than living in dark soil. I shook myself and followed Xifeng to do gymnastics. A few days later, my master gave me special care-fertilization. The master first filled the soil with water, then when the soil was slightly dry, he sprinkled fertilizer and said to me, "Little seed, you must grow up quickly!" " "I'm determined not to disappoint my master. A few days later, I grew some green leaves. My master is very happy and pays more attention to me. Come and see me first thing in the morning. I didn't live up to my master's expectations. A few weeks later, I grew a small bud. To this end, the host was ecstatic. With the help of Grandfather Sun and Sister Chunyu, I soon blossomed bright flowers. My friends and relatives came to see these flowers, and they were intoxicated by my fragrance. I am so excited! However, the good times did not last long. After a few months, the flowers fell, leaving only a few jagged green leaves on the branches. But I will never be discouraged. I will save my strength and wait for the spring when a hundred flowers blossom next year.

Although I don't have that kind of lasting happiness, I feel the value of life.

3. The law of seed growth

First of all, it is a natural phenomenon that "as you plant melons, you reap beans", which logically means "as you plant melons, you can't get beans" or "as you plant melons, you can't get melons", which is a universal law of crop growth. So, is this law equally effective for people other than crops? Although this is a strange question, the answer is quite thought-provoking. We can see the clue from some examples in daily life: 1. See if we have been in a very friendly environment? If so, it is because you have been very friendly to everyone around you at any time, that is to say, you have planted many seeds of "friendship", so you will feel the fruits of "friendship" when you need it; On the other hand, if you often meet arrogant or suspicious people, you should examine yourself. Have you ever been arrogant or doubted others' arrogance or doubts? If someone will always help you when you are in trouble, it may be because you helped others and planted the seeds of "help" when others were in trouble. On the other hand, if you are always short of "noble people" to help you, you should reflect on whether you often help others when they need it. 3. I want to borrow some money when I am short of money, or I want to borrow some money when I start my own business. It can be achieved if it goes well. That's because you are generous when others ask you for money. On the contrary, you are too stingy. Therefore, if you can't borrow money, you must take a good look at the past. Have you ever lent money to others often? 4. Look at yourself first, what you have the most, such as care, some knowledge, etc. Maybe you will find that you pay the most, and then look at yourself, what you have the least, usually that you want the most, but pay the least. ..... There are many such examples, not polite common sense, but the result of mature seeds. If none of the above examples happened to you, we can also take the initiative to verify this so-called "law of seed growth" through the following examples: 1. If you meet a car coming from the opposite side at night, don't turn on the headlights regardless of whether the other side turns on the headlights. Soon (. If someone wants to block in front of you, you are always willing to let others, so soon, when you have something urgent to overtake, there will be a car for you; 2. When you take the elevator by yourself, if you often hold down the person behind the elevator, you will find that someone will often press the elevator to wait for you soon (generally not more than three months); 3. Often help colleagues cook, ask them to have a snack without purpose, try to meet the reasonable demands and wishes of colleagues and friends, and so on. Before long (usually no more than three months), these may all come back to you; Have great respect for everyone, especially those with low social status, such as security guards, cleaners, food delivery staff, delivery staff, etc. Soon (usually not more than three months), you will obviously feel that you will get more respect on many occasions than before; If you are old and young, if, from now on, you are willing to be extremely filial and respectful to your parents, within three months, your attitude towards you will change obviously when you meet your children; ..... Of course, if you do all the above things in turn, the same result will come back to you! And the time to come back, generally not more than three months. There will be many similar examples, all of which are the results of mature seeds. What needs to be explained here is that this "seed growth law" is not one-to-one correspondence. For example, the person you helped may never help you, and the person who helped you may never help him; By extension, people who have borrowed money from you usually don't lend you money, and so on. But the positive or negative behavior you do to others will always come back to you from an unexpected place, and it is usually doubled!

4. Knowledge about plant growth

A plant is defined as an autotrophic organism that can carry out photosynthesis, transform inorganic substances into organic substances and live independently.

Classification of plant kingdom

In order to facilitate classification, according to the level of plant groups, each group is given a definite name, which is classification.

All levels of units in the world. Kingdom, division, class, order and family.

(section), genus, department.

Several different tissues * * * form a part with a certain morphological structure and perform certain physiological functions.

Divided into plants, called plant organs. Higher plants usually have six organs-roots, stems, leaves, flowers,

Fruit, seeds. Among them, roots, stems and leaves are organs for vegetative growth of plants, which are called plant camps.

Vegetative organs Flowers, fruits and seeds are the organs that plants reproduce and complete the continuation of race, which are called plants.

Genital organs.

Sunshine, air, water. The soil in nature only provides nutrients for plants and things to root, but it needs sunshine, air and water. Plants are autotrophs and feed themselves! Especially green plants, absorb CO2, release O2, and form nutrients through photosynthesis. . . . . .

5. What does a seed thrive on?

Bury the seed in the ground, give it enough sunshine and water, take care of it carefully, and it will bear fruit in autumn.

Before the fruit, beautiful flowers can bloom. I really want to plant a tree myself and see it blossom and bear fruit.

I have always liked that white pear tree, so I'm going to plant a pear tree. I didn't know what seeds were at that time. Grandpa told me that the pear core is its seed.

On a sunny afternoon, I found a suitable place in the yard, buried a pear core in it, poured a bucket full of water, and went home happily. From that day on, this seed has become my heart, and I miss it all the time.

To see the pear tree as soon as possible, I think we should give it enough water. But I don't know the word enough. I think the more the better, so I water it a lot every day.

Spring has passed, summer has passed, the weather is getting colder and colder, and autumn is coming to an end. But my little pear tree didn't blossom and bear fruit, and even its buds were not unearthed from beginning to end.

I was upset and depressed, so I went to my grandfather and asked what was going on. Grandpa found the reason and said with a smile, silly boy, how can you water all day? Isn't that already flooded? Everything should be controlled, too much doesn't mean good! However, the pear tree still hasn't grown.

As it turns out, my attempt failed. Finally, I didn't see the expected pear tree, but I increased my knowledge and learned to plant a plant. I strengthened my sense of responsibility, even in vain, but I did it with my heart.

Most importantly, I know that everything should be measured and done in moderation. For others, this is just a stupid and meaningless behavior in childhood; However, as far as I am concerned, I have gained something from it and I have gained spiritual growth.

Although I regret this attempt in my childhood, I understand that it is these seeds that have not germinated in life that have become nutrients for growth and helped me bloom in the spring of life.

6. Write about the growth experience of small seeds

Today, when I got home, I ran to the flowerpot and scratched the soil gently with chopsticks to see if the seeds germinated. Halfway through the slide, I found a white bud. I took a closer look and found that the soybeans had sprouted.

I saw that its bud sprouted from the opening of soybean, from coarse to fine, and the top of the bud was a little turquoise. However, the color of soybeans is a little lighter. There is a horizontal stripe on the surface of the bud, but it is not obvious. When the seeds germinate, the soybean skin breaks, indicating that the buds germinate from the inside of the soybean.

The shape of the bud is thin and long. My soybean is one centimeter wide and the bud is three centimeters long! How fast my seeds grow! Because the weather is fine these days, with plenty of sunshine and water, it may be this reason, or it may be that soybeans are suitable for growing in this environment.

7.20-word essay on plant growth.

As usual, we sat in the classroom and listened to the science teacher. Suddenly, the teacher said that we should complete an experiment of "planting mung beans" to compare whether plants need water, light and temperature for growth. I chose Ze to study "light". One to one

When I got home, I opened the science bag with great interest, took out the mung bean seeds and put them in paper cups, one in the sun and the other in the shade, with the same temperature as water. After I got everything ready, I went to bed.

Yes I got up the next day to brush my teeth and wash my face, and went directly to observe my mung bean seeds. Oh, the seed is still the original seed, and there is no change at all. I took up my schoolbag and went to school in disappointment.

When I came back from school at night, I found that all my seeds had pulled out a thin stem, which indicated that they had sprouted. If they germinate, it means that these seeds have not rotted. As long as they are carefully cared for, they will certainly grow into real mung beans.

Miao. After another night, when I got up in the morning to observe, the germination degree of seeds under light was higher than that on the dark side, indicating that plant growth was related to light. With this answer, I went to school for science class again.

I told the teacher the result of my experiment. But in the end, the statistical comparison of experimental results confirmed that plants do not need light for growth, so did the teacher, and told us that seeds need three conditions: sufficient water and suitability.

Temperature and air. And I said that the reason why I didn't succeed in the experiment should be that the water in the two paper cups is different. Although the experiment failed, I was not sad at all, because I learned a new knowledge.
