J C BOSE'S EXPERIMENTS ON GROWTH AND REACTION OF A PLANT
Answers
Answer:
Bose used his invention to introduce the world of plants to the humans. His invention - the Crescograph - showed how plants move
The Bose Crescograph has a series of gears and a smoked glass plate that record the movement of a plant's tip under a magnetic scale of 1/10000
The plate catches the reflection of the plant and it was marked according to the movement of the plantThe plant was dipped in bromide, a poison. The pulse beat of the plant was shown as a light spot on the smoked plate. The spots became unsteady once the plant started to take in the poison, proving that plants have life
Bose showed how plants behave differently under different environmental factors such as temperature, chemicals, electricity, gases, and humidity
He showed the electrical nature of conduction among several stimuli in plants, which were earlier believed to have a chemical nature
Bose was the first to study the action of microwaves in plant tissues and the changes in the plant cell membrane potential
Through this study, he proved that plants are sensitive to pain and affection

Jagadish Chandra Bose was more than just a botanist. He was a polymath adept in mathematics, electromagnetism, microwave technology. He is even given the credit to be the first to successfully use microwaves as radio signals.
Here are some amazing facts you must know about Jagadish Chandra Bose:
In November 1895, Bose presented a public demonstration at Town Hall in Calcutta where he sent an electromagnetic wave across 75 feet, passing through walls to remotely ring a bell and to explode some gunpowder
Bose is known as the father of wireless communication. He had invented the Mercury Coherer, a radio wave receiver that was used by Guglielmo Marconi to build an operational two-way radio
The science behind capturing radio waves was first demonstrated by Bose. While Marconi was celebrated for his
invention, Bose remained unknown to many, as he never patented his work
Bose was appointed as a professor in Presidency College (now University) in Calcutta by the order of Lord Ripon on his return from London
Being a colonised Indian, Bose was denied access to laboratories. He would conduct his experiments only at his place. He would work inside a 24-square-feet room, which is hardly enough for any scientific experiment
He was considered as the pioneer of Bengali science fiction. His book 'Polatok Toofan' (Absconding Storm) described how a cyclone could be averted by using a bottle of hair oil. It explained how oil changes the surface tension and holds water
His book 'Niruddesher Kahini' (Story of the Untraceable) was the first major Bengali science fiction
Jagadish Chandra Bose was one of the most influential teachers of his time. Two of his students were Meghnad Saha and Satyendra Nath Bose
There is a small crater on the moon named after Jagadish Chandra Bose. The Bose Crater is located at the far side of the moon close to Crater Bhabha and Crater Adler and has a diameter of 91 kilometres
