• D) Satyendra Nath Bose

The instrument known as the “Crescograph” was invented by Jagadish Chandra Bose. This remarkable device was designed to measure the growth of plants and their responses to various stimuli. Bose, a pioneering scientist in the field of plant physiology, made significant contributions to our understanding of how plants react to their environment.

Understanding the Crescograph

The Crescograph is an ingenious instrument that allows scientists to observe and record the minute movements of plants. It operates on the principle of amplifying these movements, which are often imperceptible to the naked eye. By doing so, it provides valuable insights into how plants grow and respond to factors like light, gravity, and touch.

How the Crescograph Works

• Amplification: The Crescograph uses a system of levers to magnify the small movements of plant growth. This amplification allows researchers to see changes that occur over time.
• Recording: The device is equipped with a recording mechanism that captures the growth patterns, enabling scientists to analyze the data later.
• Stimuli Response: By applying different stimuli, such as light or mechanical pressure, researchers can observe how plants react, providing insights into their behavior and adaptability.

Jagadish Chandra Bose's Contributions

Bose was not only the inventor of the Crescograph but also a trailblazer in the field of biophysics. His work laid the foundation for future studies in plant physiology and bioengineering. He was among the first to demonstrate that plants have life processes similar to animals, which was a groundbreaking idea at the time.

Legacy and Impact

The impact of the Crescograph extends beyond just measuring plant growth. It has inspired further research into plant behavior and has influenced various fields, including agriculture and environmental science. Bose's innovative approach to studying plants opened up new avenues for understanding the complexities of life.

In summary, the Crescograph is a testament to Jagadish Chandra Bose's ingenuity and his significant contributions to science. His work continues to inspire scientists and researchers today, highlighting the intricate relationships between plants and their environments.
