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 an
d 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.
