Carnivorous Plants Information 2

The meal will be lured. Since many species of insects such as ants, inform their colleagues when they increased food supplies erkundschaftet have to be with a whole retinue anzurücken, this method can be very lucrative for the plant. Can with sizes up to 20cm Nepenthes can certainly handle such quantities. The pitchers are powerful, 6000 digestive glands per square centimeter provide. Sundew (Drosera) This family has 90 species, the wide dissemination in Europe (6 species), Africa and Australia possesses. The various types come in different forms. The variations do occur in clumps of up to Schlinggewächsen, with the help of sticky sheets in their surroundings Klimmen upwards. Gears are also transformed leaves. For this we differentiates leaves three types: round (D. Rotundifolia), with the leaves around like a tennis racquet trained, the “brains” of leaves with a wealth of tentacles which, at their peak each a single droplet tauartiger digestive fluid leaking. Insects, from that, for them to nectar fragrant, fluid will be attracted and a land of leaves remain on the sticky droplets hang. By Gezappel of insects is now the real Fangmechanismus triggered. The tentacles are driving the victim to the middle leaf; knäuelt then the entire sheet. This process takes, depending on the circumstances, a few minutes or even hours. After about a week to open the leaf, the insect is digested, the remains are from or are fortgeweht. A single tentacle creates a maximum of three such fishing operations. Then he withered. Darwin already created about an elaborate experiment in a study. Another group of species Sonnentaus the leaves are long (D. Interactive Media, a common type of commercially available). Here are the leaves knäueln not together like a baseball Fanghandschuh, the victim is much more like curled in a kind of chameleon tongue. Finally, there are still some very exotic species in Africa is home, where the whole leaf densely equipped with tentacles and simply looks like a curved piece of wire (D. Filiformis). Even with these plants sitting in the flowers (small, inconspicuous, yellow to white) high above the rest of the plant to pollinators before the tentacles to protect. The rime enzymatic digestion of prey found here by the glands, which at the tops of the Tentacle sit. These glands are very versatile: They produce the sticky nectar, the Verdauungssekrete and then take the nutrients. The movement of the Tentacle has resulted from a certain river from the leaf tissue. This reallocation of certain cells to grow tissue layers, while others remain constant or even shrink. Fly traps (Dionaea) most famous and most popular representative of this family (and the carnivorous plants in general) are the Venus fly traps (D. Muscipula, domiciled in North America). The tentacles are up to 7 cm long, and rosettenförmig arranged. In the center rises a stalk with up to 15 flowers, similar to Drosera. The individual tentacle is as follows: The largest proportion, about 3 / 4, consists of leaf-like design and looks really quite usual. The trick is like a molded Fangklappe case bears at the top. In the open state, the Fangklappenhälften at an angle to each other by 50 °. The edges are canines; or in a closed state, they serve as a safe escape latticework. The inner part of the flaps is dyed red, a dye in the digestive gland secretions ensures educated. The bright coloration serves the purpose, inter alia, to attract potential food. The Schliessmechnismus works like this: On the inside flap of each half there are three hairs. Against them must be a stimulus, whether zappelnde by insects or mechanical limbs influence twice within 1.5 to 20 seconds, in order to close the door to lead. The closing process takes only a quarter second. A digestive reaction takes place only if the internal sensors of the case (on appeal nitrogenous substances) is indeed a prey can be identified. This may be an insect, but also a piece of raw meat (so you can plant at home in times of acute shortage of insects eat). The digestion of prey lasts 10 days. Then the door opens and is now ready for use again. The remains of the prey are of wind and rain away. It is still not perfectly clear, as the movement of the flaps out. Presumably, similar to Drosera. However, this also has other things to play a role. Thus, for example, weak electric currents during the closing transactions measured. Anyway, it is clear in any case, that the flaps not very often can be operated after some time leiert the mechanism and the leaf welkt. water hose (Utricularia) An aquatic Carnivorenpflanze. The species are all over the world, from Greenland to South Africa. Most species, however, live in the tropics, only 4 in Europe. Most species live in water, many are content instead with swampy, wet terrain, beat a few totally out of the epiphytic species and life (how many touchdown Orchis species). For all types of stem is rather thin, branched into many small Ästchen and then in numerous fadenartige leaves. At the purely aquatic species floats the whole plant then elegantly in the water. The land-living species, because without solid stems, as hingeschmissen on the ground. All species have beautiful, colorful flowers on long, sturdy stems high above plant ooad of. The size of this plant is actually very different. It varies between a few centimeters to one meter. The traps are small bubbles here, which stems from the normal leaves sit in the water. Previously we thought that air-filled bubbles for stabilizing the plant in water.
