Remember being surprised during school days after learning that plants are living beings? Well, they continue to surprise us even after all these years.
A new study has revealed that plants communicate when they're stressed or when they cry. The researchers at Tel Aviv University have recorded ultrasound crackles that are unheard of by humans when they're stressed.
These sounds were recorded for the first time. The sounds were distinctly emitted by the plants and resemble like popping of popcorn. The sounds are similar to human speech but at high frequencies. Therefore, they are unheard by the human ear.
The study was carried out using tobacco and tomato plants inside an acoustic chamber and in a greenhouse. The physiological parameters were also tracked. Other plants like wheat, cactus, corn, and henbit were also analyzed. The setting of the plants was changed. Some plants were untouched, some were not watered for five days, and the stem of some plants was cut.
The sounds were recorded at frequencies of 20-250 kilohertz. A human ear can only hear a frequency of up to 16 kilohertz. Artificial intelligence was used to analyze different types of sounds between different plants.
