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.
