Plant Neurobiology?

In reference to my July 25 post on "plant intelligence," coincidentally the September/October 2024 issue of SKEPTICAL INQUIRER contains an article by Massimo Pigliucci titled "Are Plants Conscious?" In his view, a science labeled "plant neurobiology," based on the idea that plants could have intelligence or consciousness, constitutes a "category mistake." Neuroscience studies "brains and their associated nervous systems," physical features of animals but not plants. He concedes that plants in a sense process information. As for responding to "environmental cues," he points out that all living creatures do that. He objects to conflating those general terms with the specific types of behavior we call "cognition" and "intelligence" in animals. Moreover, the claim that plants feel pain is extremely unlikely because, as far as anyone knows, pain and awareness of any other physical sensation require a nervous system. He proposes, "Plants are fascinating in part precisely because they are so different from animals."

If plants feel pain, by the way, consider the ethical implications of eating them. I'm reminded of the satirical song "Carrot Juice Is Murder," by the Arrogant Worms. "I've heard the screams of the vegetables, watching their skins being peeled. . . ."

The PBS network features a miniseries about the vegetable kingdom called GREEN PLANET, hosted by Sir David Attenborough:

Green Planet

Stop-motion photography produces sped-up films of plant growth to illustrate that these organisms are far from inert and passive. Attenborough's narration talks about phenomena such as seedlings and saplings competing with their neighbors for light and air, or fungus in the nests of leaf-cutter ants telling the ants what type of leaves it wants. That kind of language and the accompanying dynamic videos make it temptingly easy to view plants in anthropomorphic or at least theriomorphic terms.

Noticing how English ivy climbs our window screens seemingly overnight after heavy rains, regardless of how often it's trimmed back, I could easily imagine the vines have "conscious" intentions and preferences.
