Mysterious Venus flytrap
Venus flytrap - type of carnivorous plant-eating living organisms, such as: flies, beetles and other insects.The Latin name of the plant species - Dionaea muscipula - translated into Russian as "a mousetrap."The fact that a botanist who discovered it, Arthur Dobbs made a mistake and instead muscicipula («trap flies") wrote muscipula.
Venus flytrap - low herbaceous plant having an outlet of 4-7 leaves growing from underground bulbous stem.Leaves of needles forming a trap formed only after the first flowering. During the life of the Venus flytrap get trapped in its three insects.
slam the trap mechanism is quite complex and still not fully und
erstood by researchers.Sheet plate flycatchers consist of two parts: the bottom, heart-shaped, performs photosynthesis, and the top is just a trap.On stalks are like two halves of the shell folds, fringed with long teeth that in closing the trap take a horizontal position, crossing each other, thereby forming a lattice.Because of this insect has flown will never be able to get out.
Along the edges of the leaflets are arranged glands that produce the sweet nectar that attracts prey.The trap closes, not when an insect flies in, and when it is carried away nectar, touches one of the three sensory hairs triggers located in the center of the lamina.These hairs are colored red, the color due to the presence of the pigment anthocyanin, which attracts insects.If the fly touches the trigger twice within 20 seconds, the trap slammed shut lightning.The speed of closing the valves is from 0.0040 to 0.7 seconds. Digestion victim takes 10 days, after this period there is just a shell of chitin.
