Can Plants Think?
I have an another question: can plants think? The Sleeping Grass and the Telegraph plant can move. But could plants think? I researched about it and I’ll give you the answer.
Plants do not have brains like human beings do. They cannot think like human beings either. They can, however, contain extremely complex mechanisms that allow them to do amazing things. Although plants don’t have brains, they can tell time! Plants have time-sensitive genes that let them know when to suppress growth.
After a certain number of cold days pass, for example, these genes stop suppressing growth and allow for new growth to begin. Similar mechanisms let plants know when to drop their leaves and seeds, as well as when to open and close their petals on a daily basis.
Carnivorous plants, such as the Venus flytrap, can lie in wait and spring closed to trap insects and sometimes even frogs. They don’t use brains to accomplish this complex task, though. Instead, finely-tuned hairs are triggered by their prey. When triggered, internal mechanisms cause the Venus flytrap’s unique leaves to snap shut quickly to trap its prey. This mechanism is so advanced that it requires two different hairs to be contacted within 20 seconds of each other in order to trigger the process. This prevents accidental triggering when no real prey is present.
Plants are able to remember information and react to it, thanks to an internal communications system that can be likened to a central nervous system in animals, according to a new study by a Polish plant biologist.
Plants “remember” information about light, and a certain type of cell transmits that information, much like nerves do in animals.
In the study, which was published in the early online version of the journal Plant Cell July 16, the researchers found that light shone on one leaf of an Arabidopsis thaliana plant caused the whole plant to respond. The response lasted even after the light source was taken away, suggesting the plant remembered the light input.
“The signaling continiues after the light is off; it is building short-term memory,” said the lead author, Stanislaw Karpinski, in an e-mail message. “The leaves are able to physiologically ‘memorize’ different excess light episodes and use this stored information, for example, for improving their acclimation and immune defenses.”
The leaves remember light quality as well as quantity, Karpinski added — different wavelengths of light produce a different response, suggesting the plants use the information to generate protective chemical reactions like pathogen defense or food production.
As reported by the BBC July 14, scientists found that light shining on a leaf cell triggered a cascade of events that was immediately signaled to the rest of the plant via a type of cell called a bundle sheath cell. Those cells exist in every part of a plant. Karpinski, of the Warsaw University of Life Sciences in Poland, measured the electrical signals from those cells, and compared it to finding a central nervous system for plants.
Simply, yes. Plants can think.
Some more questions about plants:
Can plants feel pain?
As far as I know no reputable study has ever shown that plants can “feel pain”. They lack the nervous system and brain necessary for this to happen. A plant can respond to stimuli, for example by turning towards the light or closing over a fly, but that is not the same thing.
Do plants respond to music?
Plants can perceive light, scent, touch, wind, even gravity, and are able to respond to sounds, too. No, music will not help plants grow—even classical—but other audio cues can help plants survive and thrive in their habitats.
Do plants have thought?
Plants are often thought of as inanimate objects, not living beings. … We’ve known for years that plants can sense light, because they grow toward the sun and artificial light. They can also smell chemicals released by other plants, triggering specific reactions in the plant. Plants can sense gravity, and can even hear.
Can plants communicate to each other?
Plants can communicate with insects as well, sending airborne messages that act as distress signals to predatory insects that kill herbivores. Maize attacked by beet armyworms releases a cloud of volatile chemicals that attracts wasps to lay eggs in the caterpillars’ bodies.
