Which instrument is used to measure the growth of plant ?

The correct answer is Crescograph.

Key Points

• A Crescograph is an instrument used to measure the growth rate of plants.
• It was invented by Indian scientist Jagadish Chandra Bose, who is renowned for his pioneering work in plant physiology.
• The device can magnify plant growth up to 10,000 times, allowing precise measurement of minute growth changes.
• The Crescograph primarily works by recording changes in plant length or girth over time, using a lever system or electronic sensors.
• This instrument has helped establish the concept that plants respond to external stimuli, similar to living beings.

Additional Information

• Jagadish Chandra Bose:
  • He was a physicist, biologist, botanist, and inventor, known for his contributions to plant physiology and wireless communication.
  • Bose demonstrated that plants have life and can feel sensations using instruments like the Crescograph.
• Plant Growth Measurement:
  • Plant growth is typically measured in terms of changes in height, girth, or biomass over time.
  • Advanced techniques use sensors, lasers, and imaging systems for real-time monitoring.
• Other Instruments for Plant Studies:
  • Photosynthesis Meter: Measures the rate of photosynthesis in plants.
  • Chlorophyll Meter: Determines the chlorophyll content in plant leaves.
  • Soil Moisture Sensor: Monitors water content in the soil for plant growth analysis.
• Applications of Crescograph:
  • Used in research to understand plant responses to various stimuli like light, temperature, and chemicals.
  • Helps in studying the impact of environmental factors on plant growth.
