A lot of people may wonder about one thing when they think about it – is there pain in plants? Some people think it’s actually a stupid question. After all, when we cut cauliflower or weed, we’ve never heard of plants struggling to escape.
So just through a certain external static state of the plant, can we directly assert that the plant does not feel pain? What’s more, if people who have learned some biological knowledge will know that plants are not like many animals – animals are generally used by the nervous system to transmit external signals to the brain or to the nerve center for processing. Then plants do not have vocal organs. Of course, there is no such nervous system. Can they feel pain?
The surface phenomenon often does not mean the most correct essence. It is a bit too subjective to judge whether a creature can feel pain only by ordinary phenomena. In 17th century Europe, people judged whether an object is a creature by the characteristic of whether it can make sound. Plants are regarded as creatures because there is a kind of plant called Datura, which is being used When it’s pulled out, it makes a scream like sound, so people think it’s a kind of creature.
The International Association for pain research has defined pain as the adverse feelings and feelings caused by real or potential body tissue damage. From this point of view, in fact, plants can feel pain. The research shows that when plants are injured, these injured tissues will release a kind of molecule, most of which are oligosaccharides and systemINS. These substances are enough to further activate the relevant defense elites – to produce some cyanide, tannin and other substances to resist external damage.
From this we can know that the bad feeling when the plant is injured will not make him scream or run away immediately, but various indicators in the body have changed greatly.
In addition, a study in 1998 showed that aspirin, a human painkiller, can also inhibit jasmonic acid produced by plants. This jasmonic acid is a kind of uncomfortable warning given by plant tissue when it is injured – it is already in danger.
Therefore, from the current research results, aspirin can be applied not only to human body, but also to plants.
All of the above are chemical signals. In addition, electrical signals are also generated when plants are injured. In 1992, scientists conducted an interesting experiment. They frostbitten part of tomato leaves, so the frostbitten part will transmit an electrical signal to other parts, which means that although the nervous system does not exist in plants, there is a kind of filament structure between cells, which means that the nerve system does not exist in plants Silk structure plays a very important role in electrical conduction, and it has a similar effect with animal nerve conduction system.
What’s more interesting is that plants are very intelligent – after all, they can also remember their own pain. Scientists have done a group of experiments. He once stabbed the right leaf of the seedling with a needle. After a week of stabbing, he found that the right leaf of the plant grew more slowly than the left leaf. So it means that the side of the leaf does not grow because of the injury, because the plant remembers a message that it was injured. It can feel pain, in order to avoid this pain, it will be forced to reverse the direction of growth to avoid more danger.
Now it’s finally clear that there’s pain in plants.
Before all kinds of evidences, we didn’t want to believe that only human beings or humanoid animals would have this kind of pain. But now if we can learn more about science, we will find that the wonder of nature is far more complex than we think.
