What it is
The crescograph is an instrument that records plant growth using a system of gears and a smoked-glass plate, able to magnify the movement of a plant's tip up to 10,000 times to study how its growth rate varies under different stimuli.
What it led to
- quantitative experimental plant physiology
- studies on plant response to external stimuli
- precision scientific instrumentation in biology
- recognition of J. C. Bose as a pioneer of biophysics
