The new study ensures that plants are able to emit cries of pain or stress, especially tobacco and tomato plants. They can make different sounds when they are being cut or when they are starting to dehydrate. Depending on the threat you are facing, the sound will completely change.
The study was published on Cell and emerged to innovate the ideas we have of a plant.

Plants can scream in cases of pain and stress
These plants are capable of emitting signals that animals are capable of perceiving. According to the study, tomatoes that are not watered begin to emit sounds from the second day without water, although apparently everything is normal. That's what mathematician Lilach Hadany of Tel Aviv University, co-author of the study, said.
The sounds cannot be picked up by human hearing, but are similar to hearing popcorn popping and can be similar to the volume of human speech. These sounds will vary, as it depends on the plant and how it was injured, as the dehydrated plant and the cut plant emit different sounds.
Research tells us that organisms that can hear the sounds emitted to plants consider a landscape with lots of sounds and lots of information. Hadany, co-author of the research, is a leader in a laboratory at the University of Tel Aviv, in Israel, and indicated that she uses machines to identify the evolution of plants.
In the evolution of plants, there is also the acoustic field capable of producing sounds that the plant has. Recently, researcher Richard Karban, from the University of California, suggested another possibility. Research emerged stating that plants are able to send signals to other plants by releasing small chemicals into the air.
Bee sounds are picked up
In the same laboratory as Hadany, there are other studies indicating that plants are able to emit sounds, changing the behavior of other plants through what they are able to hear. The best part certainly comes now!
The team emitted the sound of bees buzzing near a particular bush of primrose plants. Upon hearing the sound, the flowers began to release the sweetest nectar, and this only happened when they heard the buzzing of the bees.
This indicates that the flowers were able to “hear” the sound of the bees, and this is one explanation for understanding why the insects are buzzing near the flowers.
The team published the study in Ecology Latters https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6852653/ in 2019. For Hadany, listening and knowing how to interpret what plants say is extremely important, as they have a greater need to interact and respond to the environment.
