Answer 1

Answer:

Jagdish Chandra Boss

Sir Jagadish Chandra Bose is one of the most prominent first Indian scientists who proved by experimentation that both animals and plants share much in common. He demonstrated that plants are also sensitive to heat, cold, light, noise and various other external stimuli. Bose contrived a very sophisticated instrument called the crescograph, which could record and observe plants minute responses to external stimulants. It was capable of magnifying the motion of plant tissues to about 10,000 times of their actual size and, in doing so, found many similarities between plants and other living organisms

Answer 2

Answer:

In 1895 in Calcutta, he publicly demonstrated wireless transmission of electromagnetic waves for the first time anywhere in the world, using the waves to ring a distant bell and thereby to explode some gunpowder, according to a biography at Christ's College, University of Cambridge, where he studied natural sciences.
