The pitcher plant is a famous insect-eating plant, its “homeland” is in tropical Asia. Pitcher plants grow in arid lands, their roots do not develop, and they do not absorb enough nutrients from the soil.
To survive, the leaves of the pitcher plant gradually evolved a magical part – an insect-catching bag, to solve the problem of lack of nutrition.
The insect-catching bag of the pitcher plant looks like a vase, the mouth of the vase secretes a sweet liquid that attracts flying insects. Because the mouth of the jar is very slippery, small insects can easily fall inside, making it almost impossible to escape. The bottom of the jar will secrete digestive juices, and soon the insects will be completely digested.
