含羞草

前，我在老家的九龙山的山坡上见过含羞草，听爸爸妈妈说，这种植物是多年生草本植物，但又不像另外的草本植物那么柔弱。

含羞草的花长得非常特殊。他开着紫红色或粉红色的花球，其实并不是一朵花，而是有许多的小花组成的花絮。如果不小心地把球上的一个小单位分开，便可以看见每一个小单位都有四裂的花瓣、四根长长的蕊，原来那一个个小单位才是它的一朵花。

可是，这种植物为什么会叫含羞草呢?哦，原来如果你轻轻的触动他一下，他那片开放着的羽状复叶，立即闭合起来，紧接着整个叶子又垂下来了，显露出“害羞”，而是植物受刺激和震动后的一种反应。正中反映在生物学上称为感性运动，是含羞草受到刺激后，细胞紧张改变的结果。

从以前的观察来看，今天我还是得到了很多收获的。至少我懂得了含羞草为什么叫含羞草以及它是怎么“害羞”的。

含羞草也非常绿，而且还绿中带青。

Before, I saw Mimosa on the slopes of Jiulong Mountain in my hometown. I heard from my parents that this plant is a perennial herb, but it is not as delicate as other herbs.

Mimosa flowers are very special. He has a purple or pink flower ball, which is not actually a flower, but a tidbit composed of many small flowers. If you accidentally separate a small unit on the ball, you can see that each small unit has four split petals and four long stamens. It turns out that each small unit is its flower.

However, why is this plant called mimosa? Oh, it turns out that if you touch him lightly, his open pinnately compound leaves immediately close, and then the whole leaf hangs down again, revealing "Shyness" is a reaction of plants to stimulation and vibration. The neutral reflection is biologically known as sensory movement and is the result of changes in cellular tension when the mimosa is stimulated.

From previous observations, I still get a lot of gains today. At least I understand why the mimosa is called mimosa and how it is "shy".

Mimosas are also very green, with a hint of green.
