Backster stated that, to his immense surprise, "the tracing began to show a pattern typical of the response you get when you subject a human to emotional stimulation of short duration". Unfortunately, when scientists in the discipline of plant physiology attempted to repeat the experiments, using either identical or improved equipment, the results were uniformly negative. "Plant perception (a.k.a. As far as I know no reputable study has ever shown that plants can "feel pain". Share Tweet Donate. Plant perception or biocommunication is the paranormal idea that plants are sentient, that they respond to humans in a manner that amounts to ESP, and that they experience pain and fear. Mythbusters - Plants have feelings (primary perception) - YouTube. As soon as the plants hear the noises, they respond with several defense mechanisms [source: Feinberg]. Because a polygraph or 'lie detector' can measure electrical resistance, which would alter when the plant was watered, he attached a polygraph to one of the plant's leaves. [1], John M. Kmetz noted that Backster had not used proper controls in his experiments. His 1880 book The Power of Movement in Plants attempted to show how plant behavior adapted to any environment.

But how much do the re-searchers really know, and can they answer the perennial question, “Do plants feel pain?” This was a topic that interested Charles Darwin. After isolating the plant, the polygraph showed a response slightly less than one third of the time. The galvanometer showed a reaction about one third of the time. Uprooting a carrot or trimming a hedge is not a form of botanical torture, and you can bite into that apple without worry. However, it seems that many plants can perceive and communicate physical stimuli and damage in ways that are more sophisticated than previously … These are the same type of cells that transmit information from our senses, allowing us to smell, see, hear, […] Bose invented various devices and instruments to measure electrical responses in plants. Studies show that plants can feel a touch as light as a caterpillar’s footsteps. But let’s dive a bit deeper. Galston, Arthur W; Slayman, Clifford L. (1979). Vegetarianism is the equivalent of genocide against plants, due to the fact that you have to murder more plants to equal the amount of energy you would receive by eating a plant. Glutamate is the most important neurotransmitter in our central nervous system, and it plays exactly the same role in plants, except with one crucial difference: plants do … [9], According to biologist Patrick Geddes "In his investigations on response in general Bose had found that even ordinary plants and their different organs were sensitive— exhibiting, under mechanical or other stimuli, an electric response, indicative of excitation. The main highways of plant transport consist of vascular tissue – xylem cells transporting water and phloem cells transporting nutrients and minerals up and do… Arabidopsis (a mustard plant commonly used in scientific studies) sends out electrical signals from leaf to leaf when it is being eaten by caterpillars or aphids, signals to ramp up its chemical defenses against herbivory. Cusack, Anne E; Cusack, Michael J. Whether it is good for growth is another question entirely. Right? "[10] One visitor to his laboratory, the vegetarian playwright George Bernard Shaw, was intensely disturbed upon witnessing a demonstration in which a cabbage had "convulsions" as it boiled to death.

The idea is distinct from measured plant perception and chemical communication. The researchers grounded the plants to reduce electrical interference and rinsed them to remove dust particles. 2 comments. Not only do they hear (yes, it's true) and smell, they can also sense the presence of water, and even … Others argue that there cannot be pain without a brain to register the feeling. (2012). The science television show MythBusters did a similar experiment and concluded that plants reacted well to any type of music, whether rock, country, jazz, or classical. The experimenters, who were in the room with the plant, posited that the vibrations of their actions or the room itself could have affected the polygraph. These articles typically leverage the findings to push back at the ethics of not eating animals as if to say, if plants feel pain, then it’s really the same as eating meat, dairy, and eggs.

[7], Jagadish Chandra Bose began to conduct experiments on plants in the year 1900. None of these things are denied, BUT when it comes to feeling actual pain and physical and emotional suffering, you need a higher level of brain functioning than what plants possess and also need this handy thing called a nervous system. [17], The television show MythBusters also performed experiments (Season 4, Episode 18, 2006) to verify or disprove the concept. Scientists have also found that anesthetics work on plants. However, it seems that many plants can perceive and communicate physical stimuli and damage in ways that are more sophisticated than previously thought. Trees like to stand close together and cuddle. They can change the direction in which they grow to avoid obstacles. We just don’t know. Later experiments with an EEG failed to detect anything. Plants have pressure receptors that allow them to know when they're being touched or moved—mechanoreceptors. Biswal, Basanti; Krupinska, Karin; Biswal, Udaya C. (2013).

[11], In the 1960s Cleve Backster, an interrogation specialist with the CIA, conducted research that led him to believe that plants can communicate with other lifeforms. For some researchers, evidence of these complex communication systems -- emitting noises via gas when in distress -- signals that plants feel pain. Over the years, several studies have indicated that plants may respond to sound. First of all, vegetables do not have brains or a nervous system. We animals, being mobile, are, unlike plants, equipped with bodies with pain receptors for our survival, but even if plants are in some way able to feel distress, as vegans, we harm a tiny fraction of the plants that eating the flesh and secretions of animals requires. (1978). Mescher, Mark C; Moraes, Consuelo M. De. While these plants visibly display a clear sensory capacity, recent research has shown that other plants are able to perceive and respond to mechanical stimuli at a cellular level. Do plants feel pain? Given that plants do not have pain receptors, nerves, or a brain, they do not feel pain as we members of the animal kingdom understand it. If playback doesn't begin shortly This investigation used a total of 60 brine shrimp deliveries to boiling water while Backster's had used 13. What’s the Difference Between Angiosperms and Gymnosperms?
