In the plant world, adaptive mechanisms and safeguards have created many plants are plentiful.Though always tied to the ground, unable to move, but they are not only the victims stood motionless waiting for the next dangerous look. In fact, some species grow spines to protect them from herbivores, even killing those species. Some plants even secrete compounds to warn fellow lurking danger.
According to the synthesis of the Britannica site, with 9 plants protection mechanism, in which only the so-called “spikes” in Vietnamese has several different types.
Type the name of thorns Thorn English is essentially the sharp twigs or stems (branch or stem). Thorns of the lemon trees, oranges, tangerines … of this type. Despite the “Every Rose has its Thorns” – Pink does not have spines, thorns of roses but not this kind.
Mechanism of thorns? Of course, then stabbed. Crashing into things harmful to them.
As said, the commission has a different kind of thorns, not like the kind just mentioned. It protrudes from the bark of the tree, such as freckles, but very sharp. They form a protective shield of trees. Often this type of very dense spikes and short, sharp, sharp, however, still have some kind of small hoppers that can squeeze into such spines and suck the sap, pretend to be a thorn to avoid the predators.
This type is the type commonly found thorns on a cactus. They help protect cells succulent plant from other species, while somewhat less cover the sun’s harsh desert (prickly cactus in the desert outside the usually smaller). According to scientific literature, the prickly cactus leaves main objective was to help the tree turn reduce evaporation while the arid desert life.
If unfortunately touch the nettles, you will know the plant hairs can cause pain like. Nettle and some others have a bristling coat to protect them. If moths landed on these feathered trees, sooner or later they will be few that fiber body piercing. Some plants are capable of spreading poison on the wounds they cause. More specific, some other types can cause permanent neurological damage and even lead to death.
5. Di compatriots:
Do not plant defense mechanisms also clearly revealing. If you see the types of spines and hairs that barrier, the cell is simple as that mines. These special cells containing defense compounds ranging from sharp crystals to the painful nature. Allergies are triggered when people first defense class has been broken. Mon tree of life (pictured) often contains simple cells secrete calcium oxalate crystals in the mouth of any animal to eat it, then secrete a similar enzyme poison of reptiles – lead to paralysis.
4. Student Union
Many plants need to be “mercenaries” to protect them. Some Acacia species in South America and Africa is both a home and is the food for the ants. These ants live in the trees and eat thorns that plants secrete substances as a food for them. Conversely, is protected from attackers trees from animals, plants, or fungi.They even bite the leaves of any kind of tree would dare enter the area surrounding our plant. In some experiments, when people away from the tree, the tree species is dying.
Shame tree (Mimosa pudica) is typical for this mechanism. We closed the leaves back when touched, making them look like dead, unattractive to other species.
2. Chemical Signals
Some crops are attacked by insects or suffer the harsh conditions such as drought can warn other plants by releasing organic compounds volatile (VOCs). These compounds are precipitated on some trees around. This may increase the amount of toxins to repel the enemy, or the tree itself will own secrete compounds to lure them into it. Some recent experiments have also shown that plants can communicate through chemical substances secreted by roots or even through a network of symbiotic fungi
It is well known that many plants are poisonous. But things stand with this species is not necessarily toxic to other species. Such as birds, are not affected by urushiol, the toxic ivy and even enjoy their consequences.Monarch butterfly earrings and eat plants absorbing Sub glycosides produced by trees in their tissues, making them poisonous to predators species. Of course, people took advantage of this to make a kind of toxic pesticides or other types of poison.
