Can Plants "Hear" Running Water? — In Defense of Plants. The peas were allowed to grow for five days and afterwards were checked to see which direction their roots were growing.
Amazingly, the peas seemed to be able to distinguish the sound of actual running water even when there was no moisture gradient present. Peas given the option of sitting or running water in a tube grew their roots towards the tube a majority of the time. Again, this was in the absence of any sort of water gradient in order to eliminate the chances that the peas were simply honing in on humidity. Interestingly, plants that were played the sound of running water and white noise through speakers seemed to do what they could to avoid the noise. Although the research did not investigate why the peas had an aversion to the recordings, Dr. BBC Radio 4 - The Life Scientific, Ottoline Leyser on how plants decide what to do. Untitled. Harvard John A. Paulson School of Engineering and Applied Sciences. It is well known that as plants grow, their stems and shoots respond to outside signals like light and gravity.
But if plants all have similar stimuli, why are there so many different stem shapes? Why does a weeping willow grow downwards while nearby poison ivy shoots upwards? Using simple mathematical ideas, researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) constructed a framework that explains and quantifies the different shapes of plant stems. The research is published in the Journal of the Royal Society Interface. “We have combined, in one theory, a plant’s ability to sense itself and its environment while being constrained by gravity and its elastic nature,” said L. The diversity of morphologies seen in your garden may follow from very simple causes. Plant-Perceiving Is Plant-Thinking.
There is nowadays a growing scientific consensus that plants are capable of sensing variations in their environment, from changes in light to humidity gradients, from gravitropism—or the pull of gravity determining the upward growth of shoots and the downward extension of roots—to varieties of touch.
Yet, the bone of contention, unlikely to be chewed through any time soon, is the so-called question of plant intelligence: Can plants think? In the conclusion to his influential book What a Plant Knows? Plant scientist Daniel Chamovitz veers on the side of caution. Rousseau’s Walnut and Willow Trees.

No one who is even cursorily familiar with the social and political thought of Jean-Jacques Rousseau would be surprised that he was an avid botanist and a lover of plants. It is easy to detect is a direct link between Rousseau’s ideal of a more simple and nature-bound human existence, his critique of alienation from nature, and his search for solitude, peace, and tranquility in the meadows and the woods, where he undertook his small botanical expeditions toward the end of his life.

Kat McGowan’s article goes over the history of the plant signalling field, explaining how the science of plant talk, once dismissed as hokey pseudo-research, is now challenging long-held definitions of communication and behavior as the sole province of animals. Thinking like a vegetable: how plants decide what to do. Plants Talk. Plants Listen. Here's How : Krulwich Wonders... They don't have eyes.
Or ears. Or what we would call a nervous system. But plants can talk. How Plants Secretly Talk to Each Other. Up in the northern Sierra Nevada, the ecologist Richard Karban is trying to learn an alien language.
The sagebrush plants that dot these slopes speak to one another, using words no human knows. Karban, who teaches at the University of California, Davis, is listening in, and he’s beginning to understand what they say. The evidence for plant communication is only a few decades old, but in that short time it has leapfrogged from electrifying discovery to decisive debunking to resurrection. Two studies published in 1983 demonstrated that willow trees, poplars and sugar maples can warn each other about insect attacks: Intact, undamaged trees near ones that are infested with hungry bugs begin pumping out bug-repelling chemicals to ward off attack.

Cahill Received August 6, 2014. Accepted November 11, 2014. Abstract. Plants Can Tell When They're Being Eaten. By Dan Nosowitz on October 20, 2014 Eating a leaf off a plant may not kill it, but that doesn't mean the plant likes it. The newest study to examine the intelligence (or at least behavior) of plants finds that plants can tell when they're being eaten -- and send out defenses to stop it from happening. We’ve been hearing for decades about the complex intelligence of plants; last year’s excellent New Yorker piece is a good place to start, if you want to learn more about the subject. But a new study, conducted by researchers at the University of Missouri, managed to figure out one new important element: plants can tell when they’re being eaten, and they don’t like it. The word “intelligence,” when applied to any non-human animal or plant, is imprecise and sort of meaningless; research done to determine “intelligence” mostly just aims to learn how similar the inner workings of another organism is to a human thought process.

No Face, but Plants Like Life Too. Los Angeles Review of Books - What Is Plant-Thinking?: Botany’s Copernican Revolution. Triptych image: Megan Cotts, "ECU" DID YOU KNOW that plants communicate with each other through the biochemical cues emitted by their roots? That, when attacked, they produce the same substances that function as painkillers in animals and humans? That they can distinguish blue colors from red in their environments, and their kin from a plant of a different species growing nearby? The current scientific paradigm shift in our understanding of plants is comparable in its magnitude and significance to what, at the end of the 18th century, Immanuel Kant called “the Copernican Revolution” in philosophy. With the discovery that the Earth revolved around the sun, and not vice versa, the original Copernican Revolution in astronomy signaled the end of the Ptolemaic geocentric model.
Do plants have their own form of conciousness? Story highlights Vitoria-Gasteiz, Spain - When, almost two months ago, I penned an op-ed titled If Peas Can Talk, Should We Eat Them? For "The Stone" philosophy section of New York Times, I did not expect that it would stir as much controversy as it did in the following weeks. My argument was attacked by everyone from Christian fundamentalists to vegans and from neuroscientists to humanist rationalists.
Since then I have responded to some of the criticisms in another Times piece, Is Plant Liberation on the Menu? , and participated in a debate on plant ethics with the animal rights advocate, Professor Gary Francione. If Peas Can Talk, Should We Eat Them? The Stone is a forum for contemporary philosophers and other thinkers on issues both timely and timeless.
