Sir Jagadish Chandra Bose, CSI, CIE, FRS, also spelled Jagdish and Jagadis was a polymath, physicist, biologist, biophysicist, botanist and archaeologist, as well as an early writer of science fiction.
Jagdish Chandra Bose 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 Crescograph which could record and observe the minute responses because of external stimulants. It was capable of magnifying the motion of plant tissues to about 10,000 times of their actual size, which found many similarities between plants and other living organisms.
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 is how he proved that plant’s have life:
- 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 caught the reflection of the plant and it was marked according to the movement of the plant
- The 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 take in the poison, proving that plants have life
- Bose showed how plants behave differently under different environmental factor 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.
