We all know that we have to eat different kinds of food to get the nutrition that we
So eating plants is a great idea if you want to be healthy. That’s why I like to eat
things like carrots, and spinach and tomatoes.
I like to eat plants, but what if plants… tried to eat animals?
Well, there are actually a few kinds of plants that are carnivorous, meaning they eat meat.
Now when I say meat, I’m not talking about chicken nuggets or hamburgers.
I’m talking about really small animals, like insects, spiders, and frogs.
Creatures like these have to be extra careful around meat-eating plants!
Probably the most famous carnivorous plant is known as the Venus Flytrap.
Venus Flytraps have leaves at the tops of their stems that kind of look like tiny, toothy
They’re not really mouths, but they serve the same purpose: to eat flies, and other
Usually, the trap’s leaves are wide open. And the inside of the trap smells like food
to insects. So they fly or crawl right into it, looking for a meal.
But if they aren’t careful, they become the meal instead.
On each half of the trap, there are three tiny hairs. If an insect touches two of those
hairs, the trap shuts, and the slender spines around the edges of the leaves close together
tightly, trapping the insect inside.
Then the trap slowly digests its meal, meaning it breaks its food down into smaller pieces.
It’s too bad for that little insect, but it will provide energy for that plant to live.
And Venus Flytraps aren’t the only kind of carnivorous plant.
Some plants, called sundews, attract bugs with colorful red and green leaves that are
covered with a sweet, sticky “dew” that sparkles in the sunlight.
The thing is, this dew acts like a kind of glue.
Any bug that lands on its leaves looking for a meal will get stuck. And soon the plant
just starts digesting it, soaking up nutrients from the bug’s body right through the leaves.
Now, some other carnivorous plants can consume even bigger prey.
Pitcher plants, for example, have big, brightly colored leaves, curled up into the shape of
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,
lots of different creatures are drawn to its tasty smell.
They creep, crawl, jump, or fly to the edge of the tube to see what’s in there to eat.
But the top is really slippery, and there are stiff hairs all along the inside of the
tube pointing down — so once a creature starts to fall in, they can’t get out.
This clever kind of trap has allowed pitcher plants to catch not just bugs, but also make
meals of small frogs and even mice!
And finally, there are some meat-eating plants that don’t even live on land.
Bladderworts, for example, live and catch their prey in water.
These plants have tiny containers on their stems called bladders that float underwater.
Each bladder has an opening with a tiny flap on it, that can open and close, like a hidden
When insects, like water fleas, trigger tiny hairs near the trapdoor, the door swings open,
and sucks the little creature in.
So now you know — certain plants sometimes eat animals.
Like I said, it’s nice to have variety in your diet!
