Question

The objective of the above experimental setup is

• A. To demonstrate aerobic respiration
• B. To demonstrate anaerobic respiration
• C. To demonstrate the process of photolysis
  
• D. None of these

Answer 1

The correct option is B To demonstrate anaerobic respiration

The objective of the above experimental setup is to demonstrate anaerobic respiration. Anaerobic respiration is a type of respiration in which the food gets oxidised and energy is released in absence of oxygen. In this process, ethyl alcohol and CO${}_2$ are formed along with the release of energy. In this experimental setup, the germinating seeds respire in the absence of oxygen and produce CO${}_2$ which gets accumulated above the mercury.
