Question

Which scientist proved that even plants have feelings like human beings?
A. APJ Abdul kalam
B. Jagadish Chandra Bose
C. Hargobhid Khorana
D. SS Abhyankar

Answer 1

Hint: The paranormal belief that plants are sentient, that they respond to people in a way that resembles ESP, and that they experience a spectrum of emotions or parapsychological states is known as plant perception or biocommunication. The scientific community considers paranormal claims about plant sensing to be pseudoscience since plants lack neural systems. Plants' ability to detect and respond to the environment via chemical and associated cues differs from such paranormal assertions.

Complete step-by-step solution:
The idea that plants can sense emotions was first reported in 1848, when Gustav Fechner, an experimental psychologist, proposed that plants can sense emotions and that talking, paying attention, having a positive attitude, and loving may encourage healthy development. In the year 1900, Jagadish Chandra Bose began conducting plant research. Bose produced a number of methods and tools for measuring plant electrical reactions. According to his research, an electrical spasm happens as a plant reaches the end of its life cycle. Bose utilised his innovation to bring people to the world of plants. The Crescograph, his creation, demonstrated how plants move.
A system of gears and a smoked glass plate in the Bose Crescograph record the movement of a plant's tip on a magnetic scale of \[\dfrac{1}{{10000}}\]..
The plate catches the plant's reflection and is tagged according to the plant's movement.
The plant was immersed in a poisonous substance called bromide. A luminous spot on the smoked plate represented the plant's pulse beat. When the plant began to take in the toxin, the spots became unstable, demonstrating that plants had life.
Hence, option (B) is correct.

Note: Sir Jagadish Chandra Bose was a scientist, physicist, botanist, and early science fiction writer who lived from 30 November 1858 to 23 November 1937. He pioneered the study of radio and microwave optics, made substantial contributions to plant science, and established the Indian subcontinent's experimental science foundations. He was called one of the "Fathers of Radio Science" by IEEE. Bose is widely regarded as the creator of Bengali science fiction, as well as the inventor of the crescograph, a device for monitoring plant development.
