The most vigorous plant composition .

I have a pot of cacti at home. I especially like it, it is covered with "needles" all over its body, as if it is wearing a "needle coat" to protect itself. I once heard from my teacher that the cactus was adapted to the desert climate, so that the leaves turned into thorns, the stems became fat and fleshy, and there were many hairs.

The reason for its enlarged stems is to store nutrients during the rainy season and reduce water evaporation during the dry season. And I was struck by its "survival of the fittest" strain.

However, what shocked me even more was an incident that happened during the summer vacation.

I remember my cousin, who was three years older than me, came to visit, and somehow he had a sore on his foot, and he screamed in pain, and he could be said to be restless. Later, my mother found a home remedy from a book: cut off a piece of cactus, mash it, and put it on the sore.

When I heard this, I cried out, "Want to cut my baby?" No way!

It's a pretty good idea, but my cactus is definitely going to die. After a few more days, the cactus's wound slowly dried and healed, leaving only a white scar. At this time, I couldn't help but be in awe of the cactus.

Since then, I have loved cacti even more. Whenever I see that white scar, I think of its self-sacrificing spirit and its tenacious vitality, and I secretly resolve to learn from the cactus, to be a tenacious person, and to be a useful person to society.

Cactus. The cactus is a desert plant, and I am amazed by its tenacious vitality. Let's take a look at its introduction!

The cactus has a dark green color, and if you look closely, you will notice that its thick oval-shaped stem has clusters of small white thorns. This little thorn is its leaf, and if it you, you'll have to "ouch" for a while. This may be a kind of self-protection for it.

Don't look at the appearance of the cactus is very ugly, but when it opens, it beats the white peony, as if it is decorating itself. The small flowers that are as white as jade also emit bursts of fragrance, which really makes people want to pick the next one. But at this time, the little thorn will remind you to "only watch, not move!" ”

Although the cactus has a very short flowering period, withering in only one day, it is very vigorous. No matter the summer when the "red sun is scorching", as long as it is planted in the soil, it will be fine if no one shuts it up for a few days, even if it is "cold and snowflakes are falling" in winter, it still does not change color and grows tenaciously.

Cactus is a general term for the spherical species of cactus plants, which is not only a variety of complex species, but also unique and colorful, and is a pearl in a hundred gardens.

If you pay attention to taste, you can grow some "golden amber", "crimson peony", "dragon king ball", "moon palace" and other types of cactus. However, those ordinary cacti are also very "tasteful", they have strong habits, easy to cultivate, flower pots, mud pots, porcelain pots, purple sand pots, plastic pots can be used, fertilizer is also used with plant ash, rice water and yogurt residues and other uses. I hope you don't underestimate the cactus, although the varieties are ordinary and ordinary, the flowers are still beautiful and will not disappoint.

However, what is amazing is not the beautiful flowering season of the cactus, but the breeding period of its large balls and small balls. When the melons are ripe, these balls will break away from their mothers and carve out their own world, although quietly, but for those who like to raise cactus, of course, they will not turn a blind eye to all of this (it's just that I am too stupid to describe them). A cross-section is depicted like this:

Raw baby landing ball. I think it's not only lifelike, but it's also a pun and full of fun.

Haha, in fact, there are many varieties of cacti, but I can't introduce them all here!

The wildfire burns inexhaustibly, and the spring breeze blows and grows", this poem is a poem that describes the tenacious vitality of the grass. Nature is a wordless book, which taught me to understand the preciousness of life and the tenacity of life!

Human life is like grass. In a person's life, there will be many ups and downs, just like the grass, which may be scorched by the merciless fire at any time, but scorching does not mean the end of life, on the contrary, it means a new beginning of life! The relentless fire is like a bump in a person's life, it may be a disease or a heart-wrenching lesson!

But it doesn't mean the end of everything! It doesn't mean the end of life! In the long river of life, there are often many things that you can't change after your efforts, but you have worked hard for it, and in the end, you can still proudly tell people "I am successful"!

In fact, living in this world, there are many tenacious lives around you that are struggling. It's painful, but it's motivating! Let me know the preciousness of life!

I remember an incident where there was a man who was seriously ill and that was not curable by today's medicine. The pain he endured every day was indescribable!

But he fought the disease tenaciously! I remember when he couldn't walk on the ground; Remember when he was half paralyzed; I still remember that when the pain made him unable to breathe, he was still fighting tenaciously; He still smiled and said to us, "Wait until I go back"! However, he has never overcome fate, although he still yearns for a better tomorrow!

When people were still immersed in the sound of the happy firecrackers of the New Year, he closed his eyes and fell asleep as usual, but the difference was that he could not wake up, he left us forever! The pain in the hearts of each of us cannot be expressed in words. However, when we look at his ** with tears in our eyes, his sunny smile seems to tell us:

Don't feel sorry for me, although I have left you forever, but I have worked hard to fight the disease, I have no regrets, I am successful, because I have worked hard! "He may be gone from us, but there will always be him in our hearts, and he inspires me! He's like grass, he's tenacious, he's brave!

I don't think I should shed tears for him, because he is now probably starting over in another beautiful world! I should bless him silently here!

In the withering of the grass, I read tenacity! As he struggled with pain, I read life! Nature has given us infinite knowledge to experience the mysteries of it in our growing years!

In the wordless book of nature, we will read its meaning; read its philosophy; As young people in the new century, let us sing the hymn of life and hold up the sun of tomorrow of the motherland!

Let's struggle.

In the plant world, lichens are the most tenacious. According to experiments, lichens can grow at a low temperature of -273 degrees Celsius, maintain vitality after 6 years in a vacuum, and survive at temperatures twice as high as boiling water. Therefore, it can grow in the desert, Antarctica, the Arctic, and even on the back of a large sea turtle.

Why do lichens have such tenacious vitality? After a long period of research, people finally found it"Mystery"。It turns out that lichen is not a simple plant, it is composed of two types of plants"Partnership"Composition, one is fungi and the other is algae.

The fungus has a great ability to absorb water and inorganic matter, algae have chlorophyll, which uses the water, inorganic matter and carbon dioxide in the air absorbed by the fungus as raw materials, and uses sunlight for photosynthesis to make nutrients, which can be enjoyed together with the fungus. This close cooperation is the secret of the tenacious vitality of lichens.

Cactus He will not die in the cold and dry season, and he will not die after a few years of road travel.

The most tenacious plants in the plant world are desert plants.

In the desert with severe drought and extremely harsh natural conditions, there are more than 1,000 species of wild plants, including commercial wood, medicinal plants, fiber plants, etc., which are of high economic value, which is extremely surprising.

In order to adapt to the environment, the plants in the desert have their own tricks, as we all know, the sandstorm in the desert is very terrible, move, the entire sand dunes move a few kilometers, the roads, ditches, houses, etc. will be buried, but there is nothing to be done about some plants, for example, when the sand bamboo is buried by the sand, adventitious roots and adventitious buds can be sent out at the stem nodes, so as to make the plant grow again.
