Please help write an observation essay of about 400 words, thank you! It s urgent.

There are a few mimosas on the lawn in our community, and because they are different, they arouse my curiosity, so I pay special attention to observe them.

In spring, the mimosa sprouts, tender green and green, and the pole is only 1 to 2 decimeters long. In summer, the mimosa branches are luxuriant, and the leaves are very peculiar, a very thin stem, and there are some thin needle-like things on both sides, much like the leaves of the metasequoia tree. In autumn, the mimosa blooms, and the small flowers are fluffy, some pink, some purple.

Although it is small and inconspicuous, when you look closely, you will feel that it is beautiful and cute, it is a squeamish beauty, and it is very attractive. In late autumn and early winter, the mimosa bears fruit, and the fruit is like a lentil, with a green shell on the outside and seeds on the inside. After a while, the shell turns brown, and soon the seed jumps out of the shell, lands on the soil, and takes root and sprouts the next spring, and so on and so forth, from generation to generation, and it is no different from any other plant.

One wonders why when you touch it, the leaves droop and close. I couldn't figure it out, so I had to look for information on the Internet.

It turns out that mimosas used to live in the desert, and tornadoes often occur in the desert, and when the sand picked up by the wind touches the leaves of the mimosa, the mimosa will feel very painful, and the leaves will close. In the long run, it becomes a grass that closes when it touches its leaves. On the stem of the petiole of the mimosa, there is a sac that stores the liquid, which looks like a cylinder in a hydraulic press.

Usually, the pouch is filled with liquid, when you touch the leaves, the liquid in the pouch flows upwards and on both sides of the leaves, and the leaves close under the action of gravity, and after a while of calming, the liquid slowly flows back to the pouch from both sides, and the leaves are restarted.

Sometimes, I deliberately touch them and joke with them.

When I was a child, I lived at my grandmother's house. At that time, there were many beautiful flowers in my grandmother's yard. In spring, there are spring flowers and peony flowers; In summer, there are sunflowers, crab claw lotus; In autumn there are chrysanthemums and bunches of red, and in summer there are plum blossoms and daffodils.

Among them, I like daffodils the most, I like its appearance, and I like its "heart" even more. Although it is not as delicate as the peony flower, not as red as the sunflower, not as eye-catching as the chrysanthemum, and not as fragrant and intoxicating as the plum blossom. But the daffodils are slim, and the daffodils are clean and clear.

There's an even bigger reason: "Daffodils have a tenacious vitality." ”

Daffodils are known as the "Limbo Fairy". Indeed, its moving posture makes people fall in love at first sight.

Grandma's pots of daffodils are beautiful.

In January, the daffodils are blooming! Its emerald green leaves are emerald green, green and shining, green is bright, criss-crossing between the green leaves, there are a few white and flawless small flowers scattered and scattered, and the flowers are embedded with a **-like stamens, exuding bursts of faint fragrance, which is particularly elegant. Daffodils have nothing to do with soil, and rain flower stone is its "soil".

I thought: I want to be pure and white in my mind like it, without a bit of sludge. The roots of daffodils are like a big onion, and there are white roots under the roots, and they are like long earthworms around the hard rain stones, and they look very stubborn.

A gust of wind blows, Xiaohua shakes its head, swings its soft body, and seems to be dancing on the water stone in crystal clothes, which makes people feel relaxed and happy.

In winter, many flowers can't withstand the ravages of the cold and the test of fate - they wither. The daffodil, on the other hand, is not afraid, when it is cold and snowy outside, it stands proudly, still so energetic and full of life, as if fighting against the cold wind, so persevering, that people love it more and more.

I love Narcissus! Love its beauty and fragrance, love its nobility and purity, and love its tenacity and perseverance! I also want to learn from her and be a strong and brave person.
