Plants have neurons

I thought this would be an interesting addition to the science forum. Most of us humans don't realize that plants also have capabilities that are common in animal life. I think this topic could teach us a thing or two.

Plant perception (physiology)
This article is about the physiology of perception and response in multicellular plants. For "plant emotion" especially as applies to the work of Cleve Backster, see Plant perception (paranormal).

In botany, plant perception is the ability of plants to sense the environment and adjust their morphology, physiology and phenotype accordingly.[1] Research draws on the fields of plant physiology, ecology and molecular biology. Examples of stimuli which plants perceive and can react to include chemicals, gravity, light, moisture, infections, temperature, oxygen and carbon dioxide concentrations, parasite infestation, physical disruption, and touch. Plants have a variety of means to detect such stimuli and a variety of reaction responses or behaviors.

@cicerone imposter,
I read a good and long article by Michael Pollan about all this, very interesting. Hugely interesting.
I don't take it though that the scientists working on this call them neurons - close, re plant communication, but not neurons. Or maybe I somehow missed it.. but they seemed pretty clear about not calling them neurons.

Scientists debate a new way of understanding flora.

The article is one of their free ones.

@cicerone imposter,
Interestingly, this is in line with the work of Maturana, the Chilean biologist/philosopher who defined "cognition" as "the general life process" applicable to all life.

@ossobuco,
osso, I'm sure you are correct that it's really not neurons, because plants don't really have nerve cells - but something quite similar. They react to their environment in similar ways - especially for survival.

@cicerone imposter,
I don't want to reread the article at least right now. There is huge communication between plants, well explained there and it is similar in ways but still very different to the human neural system.

It's not Pollan's work, he is reporting the work of many scientists.

@ossobuco,
On my being correct - I'll bet you a beer of choice.

@cicerone imposter,
Moreso than simply reacting to environment evidently Cis there's widespread belief that they have feelings too

@dalehileman,
I remember many decades ago about plants to well when they listen to human voices and/or music.

@cicerone imposter,
That article goes into a lot of all this. I learned a lot in those 12 or so pages and won't read it again right now, but will read it again in a few weeks to consolidate my memory of the different aspects scientists are working on and their findings so far.

@ossobuco,
Yes, my sister is a vegan, and she'll flip when I share this with her.

A number of studies have shown that plants feel pain, and vegetables are picked and often eaten while still alive. Animal rights activists are often in the news, but has anyone ever protested for vegetable rights?
