Question

Why are germinating seeds taken in the experiment ? What would happen if germiatimg seeds are replaced by boiled seeds?

Answer 1

if boiled seeds are taken then there will be no respiration by the boiled seeds .

Answer 2

germinating seeds are taken in this experiment because they respire continuosly to release CO2. hence this would be absorbed by the KOH solution and the experiment can be completed.

But if boiling seeds are taken, as they do not respire to release CO2

there would be no absorption by KOH and hence no rise in water level in the bent glass tube [experiment observation].

Hey you reader hope you have a great day ahead......
