The idea that plants have some degree of consciousness first took root in the early 2000s; the term "plant neurobiology" was 1 around the notion that some aspects of plant behavior could be 2 to intelligence in animals. 3 plants lack brains, the firing of electrical signals in their stems and leaves nonetheless triggered responses that 4 consciousness, researchers previously reported.
But such an idea is untrue, according to a new opinion article. Plant biology is complex and fascinating, but it 5 so greatly from that of animals that so-called 6 of plants' intelligence is inconclusive, the authors wrote.
Beginning in 2006, some scientists have 7 that plants possess neuron-like cells that interact with hormones and neurotransmitters, 8 "a plant nervous system, 9 to that in animals," said lead study author Lincoln Taiz. "They 10 claimed that plants have 'brain-like command centers' at their root tips."
This 11 makes sense if you simplify the workings of a complex brain, 12 it to an array of electrical pulses; cells in plants also communicate through electrical signals. 13 , the signaling in a plant is only 14 similar to the firing in a complex animal brain, which is more than "a mass of cells that communicate by electricity," Taiz said.
"For consciousness to evolve, a brain with a threshold 15 of complexity and capacity is required," he 16 . "Since plants don't have nervous systems, the 17 that they have consciousness are effectively zero."
And what's so great about consciousness, anyway? Plants can't run away from 18 , so investing energy in a body system which 19 a threat and can feel pain would be a very 20 evolutionary strategy, according to the article.
