How do you write an expository essay on cactus? An expository essay describing a cactus

The cactus is one of my favorite flowers, and although it's not as showy as a rose or as fragrant as jasmine, I love the prickly prickly cactus.

The homeland of the cactus is in Mexico, which is a large desert, where many plants die of thirst, and only the tenacious cactus, which survives, is called "desert creatures".

The cactus is amazing for its indomitable character. The cactus has been on the balcony of the house for many years, never weeding, never fertilizing, and sometimes forgetting to water it, but it still stands tall. In the fiery and arid summer, some of the flowers are already depressed, but the cacti are like warriors with their heads raised and looking out at the blue sky; In the bitter cold winter, other flowers could not withstand the cold and were moved into the greenhouse, but the cactus still stood in the wind against ......the cold wind, not afraid of the harsh environment around it, and towered in the windIt has withstood the test of the scorching sun and cold wind day by day, month by month, and year by year, and has grown tenaciously.

The stems of cacti are fat and large, and come in a variety of shapes: palm-shaped, bulbous-shaped, ......The palm-shaped cactus resembles a human palm, the ball-shaped cactus is a small prickly ball that has just been inflated, and the columnar cactus is like a stick. Hey?

Where do the cactus leaves go? Oh, and it turns out that the leaves of the cactus are the little thorns full of power. In the past, it was leafy, but because the desert was exposed to the sun all year round, there was a drought and lack of water, and other plants died because they could not absorb the water.

In order to survive, the cactus leaves slowly degenerate into small thorns so that its water does not evaporate, and it can also protect itself from being eaten by animals, and at the same time, the cactus thorns can slowly absorb water from the air.

Cacti will bloom too! The flowers of the cactus are very small, with different postures and colors, ranging from dark pink, bright red, and white ......Cactus is also a kind of medicinal herb, it can reduce swelling and detoxification, ** many diseases of some cacti in Mexico is still a delicious delicacy!

The cactus is not a flower that people fall in love with at first sight, it does not have a colorful body, and its obscure noble qualities are also immensely admired by me.

Whenever "the bucket handle points to the east, the world is spring", countless green plants wake up from their slumber, buds bloom, and plants sprout. However, have you ever noticed that among the flowers, there is a kind of obscure spring greeter. It does not compete with different grasses, nor does it compete with flowers, but embellishes spring with its own pure colors to meet the test of the scorching heat.

This is the cactus.

Cactus, native to Mexico, is a succulent plant that is evergreen all year round. It blooms in summer, has reddish-yellow flowers, and grows in thorny nests. Its stems are fleshy and grow in segments.

The bottom section is the largest, and two pop up from the top. Three slightly smaller sections, with sections on top of sections. Each segment is oblong in shape.

A flat, flat piece with many small spines on it.

I praise the cactus and its extremely tenacious vitality. You see, as long as you break off a cactus, even if it is less than one, insert it into the soil, and it will grow again. It is not picky about the soil, whether it is an arid desert without rain, or a plain with spring all year round, it can grow tenaciously and adapt to its environment, which can really be described as "the four seas are home".

Some people say that cacti, like mushrooms, are impetuous, and have no real roots, but this is not the case. Dig out a cactus and you'll find that its root system is similar to that of dicots, with a myriad of slender fibrous roots. It has a large root system, which is why the cactus is adapted to arid environments.

I praise the cactus and its unpretentious, upper-minded spirit. It is different from peony, which decorates the flowers with heart; It is also different from the Eight Treasures, which expends energy on the branches. Its clothing in all seasons is emerald green, such as the nobility of orchid bamboo.

It has only one main trunk, and although it branches up, it is closely united and becomes a complete whole.

I praise the cactus, especially its character.

On the balcony of my house, there is a very inconspicuous pot of cacti.

The cactus' body resembles a piece of emerald, and it resembles a cute little hedgehog. Its whole body is covered with thorns like steel needles, don't underestimate these thorns, this is the ** it uses to defend itself!

I was stabbed by it, and my mother was stabbed by it, and it hurt terribly. My mother tried to throw it away many times, but I refused because I had a special affection for it, and I loved the cactus.

Spring came, everything woke up, and a small cactus was drilled into the body of the cactus "mother", and the little cactus looked so weak and so brittle, as if a gust of wind could blow it away. And its "mother" is afraid that her children will be "bullied" by the cold wind in early spring, and always uses her body to block the cold wind, but the little cactus always drills up, and finally, with the encouragement of Grandpa Chunlei and the help of Sister Chunyu, the little cactus overcame many difficulties and grew up.

In late spring and early summer, the cactus grows buds, and it is strange to say that the cactus blooms in a very "order", always two flowers bloom together, like a pair of twin sisters, and like a bow tied on the head of a little girl. The cactus flowers bloom white and fragrant, like a beautiful fairy wearing a white dress, while dancing gracefully on the jade stage, from the dress, exuding an intoxicating fragrance.

In autumn, the harvest season, the cactus grows, and it can be used for many purposes! It can be cut into slices and brewed into a cool and delicious tea to quench your thirst. It can also be eaten, it is rich in nutrients, and it can be used as a bonsai ......It's really too much to say, but the most surprising thing is that it can be boiled into a potion to cure diseases.

People love the magnificent peony and peony, the autumn chrysanthemum in a variety of forms, and the fragrant osmanthus ......But I love the cactus only because of its appearance, but also because of its quality.

The explanatory text describing the cactus is as follows:

Its indomitable personality is very surprising, and it doesn't care if there is water or no water, it is hot or cold. The emerald green body has palm-like stems covered with hard thorns, and a "green palm" grows a "small green hand", which makes people reverie. The shape of the cactus is like a large, strangely shaped hand, which is stretched wide open, and it is really unsightly.

Dressed in yellow and green, full of small thorns, as long as your fingers are in close contact with it, even if you touch it gently, you will definitely tie it, pinch it too hard, and it will bleed. So people don't like it!

It grows in the desert, and in the hot summer, its skin is smooth and its plants hang their heads, and the cactus is like a warrior holding its head and looking at the blue sky; In the cold winter, other plants have long since died, but the cactus stands proudly in the wind despite the wind and frost, not afraid of the surrounding environment, as if it is like a warrior guarding the border.

Cactus, a wide range of uses, contains protein, calcium, iron, vitamins, etc., plays a role in lowering blood sugar, lowering blood pressure, clearing heat and detoxifying, detoxifying and building muscle, etc. When you are very thirsty in the desert but have no water, the cactus will dedicate its life to quench your thirst and keep you away from death. That's how it serves us in obscurity, sacrificing itself for us.

Cacti do not have plants that make people envious at the first sight, nor do they have colorful bodies. It was covered with needles, and it made people feel a chill at the sight of it. How admirable is its noble quality of obscurity and selfless dedication!

In life, there are many such obscure people, such as cleaners, who clean up our city early every morning, and they make the sprinkler of Floo pour out a fresh dawn; It is they who wield brooms to wipe away the dirt of the city, and quickly make the city neat and clean, with a radiant appearance.
