Experiment to prove that carbon dioxide is produced during respiration in germinating seeds
Answers
Answer:
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.
Explanation:
Suspend a small test tube containing 20% potassium hydroxide. Dip the free end of the bent tube in a beaker of coloured water. Carbon dioxide released during the aerobic respiration is absorbed by potassium hydroxide and creates a vacuum and causes rise of water in the bent tube.

ANSWER
Put some germinating seeds in a conical flask.
The conical flask is fitted to a delivery tube bent twice at right angles by means of cork.
Suspend a small test tube containing 20% potassium hydroxide.
Dip the free end of the bent tube in a beaker of coloured water.
Leave it for a day. Note the changes.
The germinating seeds respires aerobically by utilizing the oxygen in the flask.
Carbon dioxide released during the aerobic respiration is absorbed by potassium hydroxide and creates a vacuum and causes rise of water in the bent tube.
If we put a burning candle in the setup, the candle extinguishes which proves oxygen is utilized by germinating seed for respiration.
