食肉。。植物!!

Meat-Eating Plants

我们都知道我们要从不同的食物中
We all know that we have to eat different kinds of food to get the nutrition that we
获取我们所需的营养
need.
所以如果你想要健康,就吃蔬菜吧。这就是我喜欢吃
So eating plants is a great idea if you want to be healthy. That’s why I like to eat
胡萝卜、菠菜和番茄等蔬菜的原因。
things like carrots, and spinach and tomatoes.
我喜欢吃蔬菜,但是如果植物吃动物会怎么样?
I like to eat plants, but what if plants… tried to eat animals?
事实上有许多种类的植物是肉食性的,它们吃肉
Well, there are actually a few kinds of plants that are carnivorous, meaning they eat meat.
我现在所说的肉,并不是指鸡块或者汉堡
Now when I say meat, I’m not talking about chicken nuggets or hamburgers.
我所说的是小型动物如昆虫,蜘蛛或者青蛙
I’m talking about really small animals, like insects, spiders, and frogs.
像这些生物一定要对身边的肉食植物格外小心
Creatures like these have to be extra careful around meat-eating plants!
也许最有名的肉食植物是捕蝇草
Probably the most famous carnivorous plant is known as the Venus Flytrap.
捕蝇草在其茎的顶部长有叶片
Venus Flytraps have leaves at the tops of their stems that kind of look like tiny, toothy
看上去是很小的,有牙齿的嘴
mouths.
它们并不是真的嘴,但它们有同样的功能:吃苍蝇和
They’re not really mouths, but they serve the same purpose: to eat flies, and other
和其他昆虫
insects.
有时候,诱捕叶片是张开的,对于昆虫来说
Usually, the trap’s leaves are wide open. And the inside of the trap smells like food
里面闻起来像食物。所以昆虫飞或者爬进去寻找食物
to insects. So they fly or crawl right into it, looking for a meal.
但是如果它们不小心,反而变成了植物的食物
But if they aren’t careful, they become the meal instead.
在每一半诱捕器都有三个细毛组织。如果昆虫触碰到两个
On each half of the trap, there are three tiny hairs. If an insect touches two of those
毛细组织,诱捕器以及叶子边缘细长的体刺就会关上
hairs, the trap shuts, and the slender spines around the edges of the leaves close together
紧紧地把昆虫困在里面
tightly, trapping the insect inside.
然后捕食器会慢慢消化它的食物,它将食物分为小的碎片。
Then the trap slowly digests its meal, meaning it breaks its food down into smaller pieces.
对于小昆虫来说是厄运,却提供了植物生存的能量
It’s too bad for that little insect, but it will provide energy for that plant to live.
捕蝇草不是唯一的肉食植物
And Venus Flytraps aren’t the only kind of carnivorous plant.
一些植物例如毛毡苔,用其鲜艳的红色和绿色的叶子吸引虫子
Some plants, called sundews, attract bugs with colorful red and green leaves that are
叶片表面有些甜味,会黏上露珠,在太阳下发光
covered with a sweet, sticky “dew” that sparkles in the sunlight.
事实上,这些露水,就像胶水一样
The thing is, this dew acts like a kind of glue.
任何落在叶子上,来寻找食物的昆虫,都会被粘住
Any bug that lands on its leaves looking for a meal will get stuck. And soon the plant
然后这植物就会开始吞食昆虫,从叶片上直接吸收昆虫身体的营养
just starts digesting it, soaking up nutrients from the bug’s body right through the leaves.
现在,一下食肉植物,也能吃掉更大的食物(指被困住的昆虫)
Now, some other carnivorous plants can consume even bigger prey.
投手植物,举个例子,有巨大明亮,色彩斑斓的叶子
Pitcher plants, for example, have big, brightly colored leaves, curled up into the shape of
卷起来 就像管子的形状
a tube.
在管子的底部,有一小湾甜甜的液体,那就是 花蜜 再说一遍
At the bottom of the tube sits a little pool of sweet liquid called nectar. Once again,
很多不同物种都会被它的香味吸引
lots of different creatures are drawn to its tasty smell.
他们 爬行,匍匐,跳跃,或者煽动翅膀,来到管子的边缘,看这里是不是有什么吃的
They creep, crawl, jump, or fly to the edge of the tube to see what’s in there to eat.
顶端确实很滑 而且向下的管道内部长满了硬毛
But the top is really slippery, and there are stiff hairs all along the inside of the
所以一个生物一旦掉进 就无法逃脱
tube pointing down — so once a creature starts to fall in, they can’t get out.
这个聪明的陷阱允许投手植物不仅是捉虫子
This clever kind of trap has allowed pitcher plants to catch not just bugs, but also make
还可以尝到小青蛙甚至是老鼠
meals of small frogs and even mice!
然后最后有一些肉食植物甚至不生活在陆地上
And finally, there are some meat-eating plants that don’t even live on land.
例如狸藻在水中生活和捕捉他们的猎物
Bladderworts, for example, live and catch their prey in water.
这些植物在它们的茎上有小的容器叫做囊袋浮在水下
These plants have tiny containers on their stems called bladders that float underwater.
每个囊袋有一个开口上面有一个可以开关的小片
Each bladder has an opening with a tiny flap on it, that can open and close, like a hidden
就像个藏着的活板门
trapdoor.
当昆虫像水蚤触动了活板门旁边的小毛 门会打开
When insects, like water fleas, trigger tiny hairs near the trapdoor, the door swings open,
并且吸进小生物
and sucks the little creature in.
所以你现在明白了吧 一些植物是可以吃掉动物的
So now you know — certain plants sometimes eat animals.
就像我说的,均衡饮食没什么不好
Like I said, it’s nice to have variety in your diet!
