In order to study and prove a particular physiological process in plants, the following experiment was set up. Study the same and then answer the question that follows:
What is the function of soda lime in the bottle 'A' and why is limewater placed in bottle 'B'?

उत्तर
Soda-lime is kept in bottle 'A' so as to check the (presence of) passage of CO2 present in bottle 'B'. This is because soda lime has a tendency to absorb CO2 present in the air.
The limewater present in bottle 'B' shows that no CO2 is entering bottle C with the air passing through bottle C.
