Question

Which of the following Indian scientists discovered that stimuli in plants are due to electrical impulses?
1. C. V. Raman
2. J. C. Bose
3. Hargobind Khurana
4. Y. Subba Rao

Answer 1

Correct Answer - Option 2 : J. C. Bose

The correct answer is J. C. Bose.

• J C Bose was born on 30 November 1858 in Munshiganj, Bengal Presidency, British India. The place is now in Bangladesh.
• Bose invented the Mercury Coherer which is a radio wave receiver. This device was used by Guglielmo Marconi to build a radio. Bose was thus a key figure in the invention of the modern radio and also in sonic technology.
• Bose contributed significantly to the development of remote wireless signalling. He was also one of the pioneers of wireless communications.
• In 1894, Bose demonstrated in Calcutta that communications signals can be transmitted without wires by sending electromagnetic waves 75 feet passing through walls and remotely ringing a bell and igniting some gunpowder.
• Acharya Bose was also renowned for his work on the physiology of plants.
• He was the first person to prove that plants feel pain and understand affection.
• He demonstrated the electrical nature of plant stimuli (like wounds, chemical agents, etc.).
• He researched the seasonal effect on plants and also the effect of chemical inhibitors and temperature on plants. Thus, he contributed significantly to agriculture also.

Name	Discovery
C. V. Raman	In 1928, C.V.Raman discovered the inelastic scattering of photons from the molecules such that they are excited to higher levels, known as Raman scattering. It is also known as the Raman effect.
Hargobind Khurana	Har Gobind Khorana's work on electron diffraction got him the 1968 Nobel Prize in Physiology or Medicine. He shared the award with Robert W Holley and Marshall W Nirenberg "for their interpretation of the genetic code and its function in protein synthesis".
Y. Subba Rao	He discovered the function of adenosine triphosphate as an energy source in the cell.
