Question

Identify the experiment.

• A. Carbon dioxide is produced during respiration in germinating seeds.
• B. Heat is evolved produced during respiration.
• C. Oxygen is produced when seeds are germinating.
• D. Carbon dioxide is absorbed during the germination of seeds.

Answer 1

The correct option is B

Heat is evolved produced during respiration.

The image is the apparatus set up for the experiment to demonstrate the energy produced in the form of heat during the respiration. There is no change in temperature in the thermometer placed in dry seeds while the temperature rises in another thermometer which is fitted in the thermos containing germinating seeds as germinating seeds are respiring.
