A) some germinated seeds were kept in a round bottomed flask &some freshly prepared lime water was taken in a test tube.B) The aim of to connect glass tube to whole set up.C) The germinating seeds in the conical flask release CO2 during respiration, which is absorbed by the KOH solution kept in the small test tube. This creates a partial vacuum in the flask that forces the water up the delivery tube. Thus, it proves that germinating seeds produce carbon dioxide during respiration.
