Imagine that you’re a fly. You’re just looking for a place to rest,when you see a nice pink leaf. That looks like a
nice place to land. As you rest your feet on the leaf, you notice something strange .This leaf is hairy. You begin to
make your move, but you trigger the plant’s reaction. Snap! In one-tenth of a second, you are caught in the Venus
flytrap. You will be digested in five to twelve days.
Out of about 391,000 plant species in the world, only 600 or so are carnivorous. We call them this because they
attract, trap,and eat bugs. Like other plants, they get energy from the sun. But unlike other plants, they get their
nutrients from their prey (猎物).Carnivorous plants live in places where the soil lacks nutrients. Most plants get
nutrients from the soil. Carnivorous plants have turned to other sources.
Pitcher plants trick their prey into landing on them. They offer nectar (花蜜)bribes to the foolish insects that
would take them. True to their name, pitcher plants have deep chambers. Their landing surface is slippery. They
have inward pointing hairs, making it hard to escape. The fly lands on the pitcher plant to eat but slips into a pit
filled with digestive fluids.
Corkscrew plants have inviting stems. Curved hairs line the inside of these stems. These hairs allow insects to
go up the stems, but not back. Going forward leads to the plant's stomach. Bugs who wander into the corkscrew
plant find that they are unable to escape. They must march to their own death.
And then there are the bladderworts. They live in water and float near the surface. Their traps are like small
bladders(囊状物)hidden beneath the water. Only their flowers are visible from the surface. When bugs swim into
the trigger hairs, the plant reacts. The bladder sucks up the prey and the water surrounding it. The prey will be
digested within hours.
