Some plants emit a high frequency distress sound when they are placed under environmental stress, a team of researchers at Tel Aviv University in Israel has found.
The team, led by Itzhak Khait, examined the sounds emitted by tomato and tobacco plants when stressed by insufficient water or when their stems are cut. Microphones recorded ultrasonic sounds between 20 and 100 kilohertz emitted by the plants in both cases, the study found.
The sounds emitted by the stressed plants are at frequencies unable to be heard by humans, however the team of scientists believes some organisms can hear the sounds from up to several meters away.
A tomato plant emitted 25 ultrasonic distress sounds in the space of an hour when its stem was cut, according to the study. In contrast, tobacco plants emitted 15 distress sounds when their stems were cut.
When deprived of water, the tomato plants sent out 35 ultrasonic sounds in the course of an hour, while 11 were emitted by the tobacco plants. The team observed that the sounds released when the plants were deprived of water were louder compared to the ones when having their stems cut.
In comparison, plants not placed under any environmental stress emitted less than one distress sound per hour.
The authors noted that other plants and animalsand humans with the correct toolscould hear and listen to the plants silent screams. A moth, for example, may choose to lay its eggs elsewhere if it is able to detect that a plant is water-stressed, according to the study, which has not yet been published in a journal.
In other cases, plants could react accordingly to others which lack water, the authors suggest.
These findings can alter the way we think about the plant kingdom, which has been considered to be almost silent until now, the researchers write in their study.
The Tel Aviv University team then took the data and used it to train a machine-learning model to predict the possible frequencies plants could emit while undergoing different forms of environmental stress, such as during intense rain or wind.
The team also believes other plants may release distress sounds when placed under stress.
More investigation on plant bioacoustics in general and on sound emission in plants in particular may open new avenues for understanding plants and their interactions with the environment, and it may also have a significant impact on agriculture, the authors suggested.
The notion that sounds that drought-stressed plants make could be used in precision agriculture seems feasible if it is not too costly to set up the recording in a field situation, Anne Visscher, a fellow in the Department of Comparative Plant and Fungal Biology at the Royal Botanic Gardens in the UK told New Scientist.
How do they know it was the plant and not the shrimp that was screaming?...................
There was a TV episode which had this story line back in the 50’s or 60’s
“The Sound Machine” from the show Tales of the Unexpected

I love that movie............
There are seeds that require fire and some that need a digestive track to prepare them to sprout.
And it all works together!
So, you’re a grass mass murderer?............
Cleve Baxter, CIA scientist, inventor of the modern polygraph, documented, when wired up, plant stresses when next to other plants undergoing stress like digging up or striping leaves, that sort of thing.
Google Cleve Baxter and Plants to get many websites documenting his work.
Met him and he laments his polygraph being used as a tool to bully people.
Well, that crunching sound is them screaming in pain from being eaten alive!
One of the most extraordinary partnerships between an insect and the plant that it pollinates is that of the yucca and the yucca moth. They are so interdependent that one cannot live without the other. Actually, there are a number of species of yucca, each with its corresponding partner, a species of Tegeticula or Parategeticula moth. This mutually beneficial relationship probably started as a relationship of exploitation with the moth feeding on the yucca. This is still the case with a number of close relatives of Tegeticula, members of the Prodoxidae family.
I guess I’ll just have to eat nothing but steak from now on.................pity...............
Life in the Slaw Lane -Kip Adotta
It was Cucumber the first; summer was over.
I had just spinached a long day and I was busheled.
I’m the kinda guy that works hard for his celery and I don’t mind telling you I was feeling a bit wilted.
But I didn’t carrot all. ‘Cause, otherwise, things were vine.
I try never to disparagus and I don’t sweat the truffles.
I’m outstanding in my field and I know something good will turnip eventually.
A bunch of things were going grape, and soon, I’d be top banana.
At least, that’s my peeling.
But that’s enough corn; lend me your ear and lettuce continue:
After dressing, I stalked on over to the grain station.
I got there just in lime to catch the nine-elemon as it plowed toward the core of Appleton,
a lentil more than a melon-and-a-half Yeast of Cloveland.
CHORUS
Life in the slaw lane.
They say plants can’t feel no pain.
Life in the slaw lane.
I’ve got news for you:
They’re just as frail as you.
No one got off at Zucchini, so we continued on a rutaBaga.
Passing my usual stop, I got avoCado.
I hailed a passing Yellow Cabbage and told the driver to cart me off to Broccolyn.
I was going to meet my brother across from the eggplant where he had a job at the Saffron station pumpkin gas.
As soon as I saw his face, I knew he was in a yam.
He told me his wife had been raisin cane. Her name was Peaches:
a soiled but radishing beauty with HUGE goards.
My brother had always been a chestnut, but I could neve figured out why she picked him.
He was a skinny little string bean who had always suffered from cerebral parsley.
It was in our roots.
Sure, we had tried to weed it out, but the problem still romained.
He was used to having a tough row to how, but it irrigated me to see Artichoke,
and it bothered my brother to see his marriage going to seed.
CHORUS
Like most mapled couples, they had a lot of grilling to do.
Sure, they’d sown their wild oats, but just barley if you peas.
Finally, Peaches had given him an ultomato. She said, “I’m hip to your chive,
and you don’t stop smoking that herb, I’m gonna leaf ya for Basil, ya fruit!”
He said he didn’t realize it had kumquat so far.
Onion other hand, even though Peaches could be the pits, I knew she’d never call the fuzz.
CHORUS
So I said, “Hay, we’re not farm from the Mushroom! Let’s walk over.”
He said, “That’s a very rice place. That’s the same little bar where alfalfa my wife!”
When we got there, I pulled up a cherry and tried to produce small talk.
I told him I haven’t seen Olive; not since I shelled off for a trip to Macadamia when I told her, “We cantaloupe.”
The time just wasn’t ripe.
She knew what I mint.
When we left the Mushroom, we were pretty well-juiced.
I told Arti to say hello to the boysenBerry and that I’d orange to see him another thyme.
Well, it all came out in the morning peppers:
Arti caught Peaches that night with Basil, and Arti beat Basil bad,
leaving him with two beautiful acres.
Peaches? She was found in the garden; she’d been pruned.
CHORUS
Well, my little story is okra now.
Maybe it’s small potatoes. Me? Idaho.
My name? Wheat. My friends call me “Kernel”.
And that’s life in the slaw lane.
Thank you so mulch.
CHORUS
It’s a garden out there!
Probably the result of the study was “More $$$$tudy needed”.
Genesis 1
Then God said, Let us make mankind in our image, in our likeness, so that they may rule over the fish in the sea and the birds in the sky, over the livestock and all the wild animals, and over all the creatures that move along the ground. 27 So God created mankind in his own image, in the image of God he created them; male and female he created them. 28 God blessed them and said to them, Be fruitful and increase in number; fill the earth and subdue it. Rule over the fish in the sea and the birds in the sky and over every living creature that moves on the ground. 29 Then God said, I give you every seed-bearing plant on the face of the whole earth and every tree that has fruit with seed in it. They will be yours for food.
Back in the 70’s it was said that John Lennon went from full vegetarian to eating nothing but vitamins because he once heard a cornstalk sob when stripped of one of its ears.
Anyway, this sure sounds like a strong argument for Keto.
I make all of my vegetables beg for their lives.
Then I chop their heads off anyway.
