Complete answer:

Crescograph is a device for measuring the growth in plants.
It was invented in the early twentieth century by Sir Jagdish Chandra Bose who is one of India’s greatest scientists and is best known for his work in biophysics and plant science.
Crescograph is an Indian invention whose main purpose was to make the growth of the plants visible.
Bose uses a series of clockwork gears and a smoked glass plate to record the movement of the tip of a plant. He experimented with temperature, chemicals, gases, and electricity.
Additional information:

2. Bose subsequently made several pioneering discoveries in plant physiology.
3. He started the investigation of radio and microwave optics
