The idea that plants have some degree of consciousness first took root in the early 2000s. The term “plant neurobiology” was  around the notion that some aspects of plant behavior could be  to intelligence in animals.  plants lack brains, the firing of electrical signals in their stems and leaves nonetheless triggered responses that  consciousness, researchers previously reported.

But such an idea is untrue, according to a new opinion article. Plant biology is complex and fascinating, but it  so greatly from that of animals that so-called  of plants' intelligence is inconclusive, the authors wrote.

Beginning in 2006, some scientists have  that plants possess neuron-like cells that interact with hormones and neurotransmitters,  “a plant nervous system,  to that in animals,” said lead study author Lincoln Taiz. “They  claimed that plants have 'brain-like command centers' at their root tips.”

This  makes sense if you simplify the workings of a complex brain,  it to an array of electrical pulses; cells in plants also communicate through electrical signals. , the signaling in a plant is only  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  of complexity and capacity is required,” he . “Since plants don't have nervous systems, the  that they have consciousness are effectively zero.”

And what's so great about consciousness, anyway? Plants can't run away from , so investing energy in a body system which  a threat and can feel pain would be a very  evolutionary strategy, according to the article.
