are fairly widespread around the world. In nature, there are 450 species of similar plants that combine into six families. The basis of their diet is formed by insects, so predatory plants are often called insectivorous.
Predatory plants are a miracle of nature. They have surprisingly adapted to life in places characterized by a deficiency or nutrients in the soil. These plants have become predators! The need for survival requires them to be able to catch live prey.
Predatory plants produce food in five ways. Some of them use huntings, which are shaped like a jug; others – sticky traps; the following are traps of the Rachevan type; the fourth – sucking traps; and finally, the fifth – slamming leaves. However, it should be taken into account that the method of obtaining food is not tied to a particular family.
The trap itself usually works as follows: an insect that is attracted by the leaves or flowers of a plant, sits on one of the leaves that have a smooth surface. Slipping down, the insect sinks in the digestive juice of the plant. Over time, the plant will absorb all of its nutrients.
Predatory plants have “developed” many ways of enticing insects.
For example, in some predatory plants, the edges of the trapping leaves have a bright red color, while in others – the inner walls of the leaf secrete a saccharic substance that attracts insects.
The sarcaccia sugary fluid contains a stupefying substance.
It quickly lulls an insect in the jug, which also can not get out because of the overhanging lid – it is formed by hanging down hairs.
Any insect, hitting the inside of a jug, is doomed to perish.
This is not true. For example, larvae of mosquitoes can easily live inside it, and for adults, nothing prevents from flying and flying out of this very pitcher. Some spiders even substantiate their dwelling in it. However, most insects fall under the influence of enzymes, which accelerate the dissolution of their flesh.
The pimple attracts the victim with water.
Bubbles that protrude on the leaves of this plant lure prey. The principle of action is this: first, due to the special glands from the vesicles, water is pumped out. Then the trap valve opens, pulling along with the water and the caught insect.
Venus flytrap is a known predatory plant.
Even with the naked eye, you can see how the trap of this plant closes, the maximum size of which is only three centimeters. This plant grows in the swamps of North and South Carolina. Each leaf of the venus flytrapper is presented in the form of petiole and hamster plate. The trap itself is formed by a disc, on the edges of which there are nectar glands – they are necessary for the plant to attract insects to itself. The digestive glands, through which the venus flytrapper digests prey, are in the middle of the trap. The mechanism for triggering the trap is designed in such a way that it does not once again close, for example, in the rain: the trap collapsed after double irritation. If suddenly the sheet was closed “by mistake”, then within the next two days it will necessarily open. If the plant caught a large prey, then a leaf about a week (and maybe more) will be completely closed.
Rosyanka – another known carnivorous plant.
There are about 130 species of this plant. They can be found in the Australian subtropics, and in tropical bogs. And some “climbed” into the tundra – they can be found even beyond the Arctic Circle. The production of sundew is mostly small insects, but it is also capable of grabbing prey larger. Its name was obtained by the sundew due to the small droplets on the surface of the leaf. They attract insects on a par with the bright (reddish) color of the leaf and the smell coming from it.True, the insect has a chance to free itself until it is completely entangled in the sticky liquid.
Representatives of the genus neptens are the most powerful among predatory plants.
Approximately 80 species are included in this genus; plants grow, mainly in tropical forests with abundant moisture. Basically, these are lianas, the length of which can reach several meters. Some species grow on open sunny slopes, for example, low shrubs. Pitchers appear at the ends of the leaves, at first they are completely covered with a special lid, which opens later. Depending on the type of these carnivorous plants, the size of the jugs varies from three to forty centimeters. The color of the jugs can also be different – there is a green, brown, red and white color.
Non-artisans are capable of catching large prey.
Individual species are able to catch toads, small rodents and birds. But mostly in the diet of non-pence insects. The way food is extracted from non-pentes is somewhat different from other predatory plants. The contents of the jug protects the lid, which also serves as a landing site for flying insects. This lid, along with the surface of the pitcher itself, gives off a special nectar, which, together with a bright color, attracts prey. The insect that falls in here quickly falls down, because the inner surface of the jug is very slippery, and enters the liquid. Her enzymes process food.
The poultry has real roots.
This distinguishes them from other genera of insectivorous plants. A large number of glands are on the upper side of a leaf of these plants. The function of some is to isolate the sugary mucus – it is a trap for small insects. The task of other glands is to generate enzymes. They are necessary for digestion of food. The insects, having got on the leaf of the litterworm, naturally begin to move, hoping to get out. However, their movements lead to the fact that the leaf begins to twist, and the insect is processed by the mucus of the plant.
