Question

4. During an experiment,some germinated seeds were kept in a round bottomed flask &
some freshly prepared lime water was taken in a test tube. The flask and the test tube
were connected by a glass tube and the whole set up was kept in this way for 2 hours.
What happens after 2 hours?What was the aim of this experiment?
Write a conclusion in brief.
​

Answer 1

Explanation:

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.
