If you inflict pain on a plant, it "screams". This is stated in a Science Alert article, reports UNN.
Details
It is noted that this cannot be called a scream in the traditional sense of the word. Rather, plants emit cracking or clicking sounds at ultrasonic frequencies outside the range of human hearing, which are amplified when the plant is stressed. This may be one way plants communicate their pain to the world around them.
Even in a quiet place, there are actually sounds we don't hear, and these sounds carry information. There are animals that can hear these sounds, so there is a possibility that there is a lot of acoustic interaction. Plants are constantly interacting with insects and other animals, and many of these organisms use sound to communicate, so it would be wrong for plants not to use sound at all
The publication points out that plants under stress are not as passive as we think. They undergo quite dramatic changes, one of the most noticeable of which is the release of quite powerful aromas. They can also change their color and shape.
These changes may signal danger to other plants nearby, which in turn increase their own defenses
The authors add that plants under stress produce an average of about 40 clicks per hour, depending on the species. And plants deprived of water start clicking even more often before visible signs of dehydration appear.
Let us remind you
Earlier we reported on what to pay attention to in May and how to alleviate symptoms during the allergy season. In particular, in May, allergy sufferers should beware of pollen from trees, meadow grasses and cereals, especially rye. It is important to monitor the allergen forecast and follow the recommendations of doctors.
