As a kind of plant, pitcher plant grass can catch and eat insects with flying and crawling ability, because one of its unique organs is the small cage on it, that is, the thing that catches insects. This organ is a long and deep bottle shaped, with a small opening at the top. Once there are insects crawling in, they will not come out. They will gradually die at the bottom of the bottle and become the nutrients needed for the growth of pitcher plants.
Someone will ask, isn't it a plant? Even if the bottle is deep, it won't swallow insects. Is there any mystery? Yes, the cage of this plant is not just the bottle, but the inside of this bottle is very smooth. Once insects enter the bottom of the bottle, thousands of plant digestive glands are waiting for them at the bottom. With the secretion and corrosion of the internal digestive fluid, the insects that come in accidentally will gradually lose their mobility under anesthesia, and then Is eaten into nutrition.
In addition to its internal digestive function, pitcher plant has the ability to trap. In the upper part of the bottle, that is, the mouth part of the bottle is growing a large number of nectary glands, which secrete a large number of sweet objects, so as to lure a batch of insects who come to look for food. The temptation of delicious food makes the insects fall into the trap, step by step into the abyss of death, and they can no longer climb up.
