Plant ‘cries’: Recalling J.C. Bose

Researchers from Tel Aviv University in Israel claimed to have been able to hear the sounds emitted by distressed plants.

Details about News

When under stress, such as when they were thirsty, the researchers claimed that these plants have been producing very identifiable, high-pitched ultrasonic sounds.
This was the first time that any form of noise from plants had been discovered.

Jagadish Chandra Bose (1858-1937)

He was a physicist-turned-biologist who demonstrated more than a century ago that plants could sense pleasure and suffering in the same way that animals could.
He created the crescograph, a tool for gauging plant growth.
For his work on wireless signal transmission and on the physiology of plants, Jagadish Chandra Bose is best known.
He was also one of the pioneers in the development of solid state physics.
The p-type and n-type semiconductors were what he had expected.
Many people agree that Bose was the first to produce electromagnetic signals in the microwave region.
The invention of radio receivers by him, which allowed for wireless telegraphy, was a first.

His research on plants

Bose's straightforward studies showed that the reactions of plant and animal tissues to external stimuli were remarkably comparable. Later, using extremely advanced tools, biophysicists amply illustrated this principle.

Controversy

The "intermediates in a continuum that extended between animals and the non-living materials," according to Bose, were plants.

ethical perspective

He was approached by a powerful businessman in Europe who offered to help him patent his invention. Bose not only turned down the offer but also the idea of profiting from science since he found it repugnant.
