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 neurotran *** itters, ____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.

The idea that plants have some degree of consciousness first took root in the early 2000s; the term “plant neurobiology” was coined around the notion that some aspects of plant behavior could be compared to intelligence in animals. Though plants lack brains, the firing of electrical signals in their stems and leaves nonetheless triggered responses that hinted at consciousness, researchers previously reported.
But such an idea is untrue, according to a new opinion article. Plant biology is complex and fascinating, but it differs so greatly from that of animals that so- called evidence of plants’ intelligence is inconclusive, the authors wrote.
Beginning in 2006, some scientists have argued that plants possess neuron-like cells that interact with hormones and neurotran *** itters, forming “a plant nervous system,*** ogous to that in animals,” said lead study author Lincoln Taiz, “They even claimed that plants have “brain-like command centers” at their root tips.”
