含羞草为什么会害羞作文400字

There is the plant of without number on the world, have king flower, morning glory, rose is beautiful, still have Cang Er. They have very a lot of more characteristic severally, but have a kind of plant exceedingly peculiar, others comes up against it, it can shrink go back, it is a mimosa of bashful “ girl ”— .

世界上有数不胜数的植物,有大王花,牵牛花,蔷薇花,还有苍耳。他们各自都有很多很多的特点,但是有一种植物非常的奇特,别人一碰到它,它就会缩回去,它就是一个害羞的“小姑娘”—含羞草。

Why is she bashful? To know this answer, I consulted encyclopedia.

为什么她会害羞呢?为了知道这个答案,我查阅了百科全书。

The leaf of sensitive plant can be moved, it is to rely on its “ Peng to press action ” . In the petiole of sensitive plant, the thin wall cell that water of a “ rouses bosomy ” calls a leaf pillow, full water is divided inside. Touch sensitive plant with the hand when you, its leaf one vibration, the moisture in cell of foliaceous pillow bottom flows with two side up instantly, at that time its foliaceous pillow bottom resembles discharge shrivelled goes down like angry rubber ball, upside is roused like the rubber ball that hits sufficient air, petiole is flagging also, shut.

含羞草的叶子之所以会动,是靠它的“膨压作用”。在含羞草的柄部,有一个“水鼓鼓”的薄壁细胞叫叶枕,里面满满的水分。当你用手一碰含羞草,它的叶子一振动,叶枕下部细胞里的水分立即向上与两侧流去,这时候它的叶枕下部就像泄了气的皮球似的瘪下去,上部像打足气的皮球似的鼓起来,叶柄也就下垂了、合拢了。

While the leaf of sensitive plant is done shut exercise by stimulation, produce electricity of a kind of biology, will exciting news spreads very quickly other leaf, other leaf follows ordinal and shut rise.

在含羞草的叶子受到刺激做合拢运动的同时,产生一种生物电,将刺激信息很快扩散到其他叶子,其他叶子就跟着依次合拢起来。

Before long, after this stimulation disappears, xie Zhenxia is full of moisture gradually again, leaf is stretched afresh restorable. If often go feeling it, xie Zhenzhong's moisture with respect to time, new moisture has not enough time to complement, with respect to the state of absolutely still of meeting occurrence lamina.

不久,当这次刺激消失后,叶枕下又逐渐充满水分,叶子就重新张开恢复原状。如果经常去摸它,叶枕中的水分就流光了,新的水分来不及补充,就会出现叶片纹丝不动的状况。

Small sensitive plant actually the knowledge of under cover so much, the secret of nature is more endless, make what we explore each together in nature sealed!

小小的含羞草竟然隐藏着这么多的知识,大自然的奥妙更是无穷无尽,让我们一起到大自然中去探索一个个的未知吧!
