Carnivorous plant (carnivorous)




Carnivorous plants or plant-eating meat (sometimes called plant-eating insects) are plants that derive some or most of the nutrients (but not energy) of the inventory and consumption of animals or protozoans, most focusing on insects and other arthropods.
Carnivorous plants grow normally in places where the soil is thin or poor in nutrients, especially nitrogen, such as acidic bogs and rock serpentine. Charles Darwin wrote the first known treatise on carnivorous plants in 1875. [1]
Carnivorous plants believed to have evolved in at least 10 separate lineages of plants, which now accounts for more than a dozen species in 5 families.
These include about 625 species that attract and trap prey, produce digestive enzymes, and absorb the resulting available nutrients.
The insect-eating plants of the signs of God-making function on its ability Almighty, and Badi created insect-eating plants, these plants grow in the land of a few organic materials, so you see it has provided so that they can capture insects, and their bodies absorb. And no wonder that each type has mutated to suit the diet of mutation surprise the practitioner. In this our theme will be talking about some plant-eating insects and how to plant predation and prey survival, careful not to.
Predator or plant-eating insects are like all other plants produce their own food-sufficient in energy by converting light (the sun) to chemical energy (in the presence of water and some of the elements), but has mutated to enable members to grasp some insects and small animals and then Afterasha to be an additional source of nutrition, and the environmental basis for this is that these plants grow in poor soils and wetlands in nitrogen facilitator for the God-given parties in a particular way to be able to eventually eat small prey, recouping their lack of nitrogen, the most important characteristic of these plants is their ability to digest the prey's body. Is not a predator plant organ Himia, so how was able to digest the animal's body protein and fat?!?
Most plants are predatory digest its victims through the secretion of enzyme analyst, but some rely on enzymes produced by bacteria, the analysis of prey Vimits decaying plant particles.
Hand, there are predators depend on each of the secreted enzymes and enzymes to analyze the bacteria. One of the ways the so-called exotic bugs that crawl around Junkie trap plant predator addresses and hearty meal of insects in the trap pipe without falling, and then cast into the trap Bgaith who shall plant because it is absorbed and decomposed meal ready for digestion.

How to move those plants and applied to the prey with amazing speed and we know they do not have the muscle tissue?!
There are two ways for this:
I: movement is a result of the sudden shift in water pressure, when you touch the trap prey cells interior walls transfer water to the external walls yields a sharp contraction and fast.
II: produced by the growth of cells in one aspect of the probe faster than the other side resulting from the developing side dishes.
Certain types of carnivorous plants, insects and how to catch their prey:
Anisz in the plant, the leaves in the form of a jar lid is closed in the case of small paper, and then suddenly open the cover after completing the growth of the paper, and fill the jar with liquid water produces acid from glands located on the inner surface to attract insects which, if I stood on the edge, they glide Yesterday's surface, or attracted to the bottom of the jar bristles minutes, and when they fall into the liquid inside the jar, close the lid to prevent escape, and the plant secretes enzymes to digest the insect and then absorbed. In Aldrosera plant, covering many papers Bzoaid end edges venom glands secrete sticky substance acidic, if insects landed on top of these appendages, they are attached, and whenever you try to escape the tag of engagement increased until redundancies gather around, and the plant secretes digestive materials which melt body insect, and after the absorption due to redundancies moderation, and returns the paper to its original form.
If we take the largest size of the plants predatory *** comfort is the first vine may extend to ten meters, and in the vineyards there is this *** trap or traps to predict prey up to the size of the frog, and some in very rare cases may seize the birds or rodents, but these victims be very weak as a result of illness. The Venus fly-trap on the small size of the most intimidating the brutality of performance, and finds teeth of paper are applied quickly and terrifying to the capture of prey is believed to be about the tiger jaw breaker.
So that we know how to respond to the carnivorous plants from insects, we find that each type of method is different from other plants in the hunt prey, and this in fact a small plant size, member will predator does not exceed, the size of the palm or finger, in addition to these members for soft and thin with the exception of a few of them, and in all cases, Members are predators of these plants are the traps does not accept more than a small-sized frog patient, so you can not attack us.
Some types:
Venus fly-trap: - There is a plant in a small area of coastal areas in the states of North and South Carolina, in the United States. A plant carnivorous (eat meat). One where the insects between the papers and the Bhimha. This plant grows in the marshes that lack of nitrogen to the soil, so the insects replace nitrogen in food plants. Rising up Venus fly-trap to about 30 cm, and get the paper consists of moving the race valves Middle. And the upper surface of each valve three sensitive bristles, and the edges are surrounded by sharp spines. When an insect affecting one of these capillaries, closing valves so that further locking the insect inside.
Nada plant the sun: who lives in South Ofriqiahit sends this plant material for the adhesive to attach Sairath the victim is not able to escape and then apply it and devour it also Basarp Hadmp and get a nitrogen that is within the structure of the proteins important to the growth of this plant. Most of these plants live in a push to the soil element nitrogen.
