Jagdish Chandra Bose was a great Scientist. He thought that there was a similarity in the behaviour of both plants and living things. They could also become ‘tired’, ‘depressed’ or ‘happy’. This was contrary to the common belief. So people laughed at him. But Bose wanted to prove the truth of his belief. He invented a machine called Crescograph. This machine could measure the growth of plants. It showed that the plants were capable of feeling. They reacted to manures, noise and other stimuli. It also showed that plants had a keen sense of sight. They had a special sense with which they knew that a stranger was coming.
