Nature has many things to human beings. As long as you observe it with your heart, practice it yourself, and be good at summing it up, you will find many mysteries.

My grandpa is a flower-cultivating fan, and his family planted many flowers. Spring is here, and all kinds of flowers are racing to open and fight for beauty, and from time to time, a butterfly dances in the sea of ​​flowers.Of these flowers, I am most interested in that pot of fly wormweed. Grandpa used to say that fly wormweed can eat flies, but I was doubtful: how can plants eat animals? But grandpa is a "know-how", his words are very scientificYes, I decided to come to see what is true. In order to understand this mystery, to confirm whether Grandpa was telling the truth or not, last summer, I came to Grandpa's house to learn how to eat "flies".fly.

For several days, I was quietly waiting for the fly worm, and patiently observed the fly worm: the leaves of the fly worm were oval, divided into two petals along the midrib, like two clam shells spread out, and the leaves were usuallySpread it out. From time to time, a special scent is emitted from the leaves ...

Kung Fu is worthy of someone who cares about it. At noon one day, a “humming” sound suddenly sounded out of the window. Sure enough, the aroma attracted a fly. The fly hovered in the air, and fell on the fly moss from time to time.Without any reflection, I just went in boldly, and the leaf of Pyrethrum immediately poured a lot of liquid, firmly stuck to the flies, and then immediately closed the leaves. About half an hour, the leaves slowly opened. I went onAt a glance, only the limbs and wings of the fly are left inside.

In order to prove once again that the fly worm can eat flies, I put my forefinger in. The inside is sticky and the leaves are closed, and the more my index finger is tightened, the more my index finger feels itchy.Pull out forefinger.

So how does Flytrap "eat" flies? I turned over my silent teacher, "One Hundred Thousand Whys." It turns out that there are many sensitive glandular hairs on Flytrap, when the flies fall on the leavesAt the time of touching, the glandular hair glands are touched to secrete a viscous digestive enzyme, which firmly sticks to the fly and makes it unable to fly up. Then, the mussel shell-shaped leaf suddenly closes, and the tooth-like bristles on the leaf edge are tightly intersecting.

Wrap the flies inside, and then the digestive enzymes work, slowly digesting the flies into a liquid, flowing into the roots, and becoming their own nourishment.

Oh, it's so amazing!

Nature is really amazing. As long as we use scientific "weapons" to deal with it, I believe that the secrets will be unlocked one by one after all.
