The experimental setup consists of a conical flask, beaker a cork and a glass tube bent at right angle.
Carbon dioxide evolved in respiration is absorbed by KOH solution.
Therefore water level in bent tube rises.
The rise in water level indicates that carbon dioxide is produced in germinating seeds during respiration.
This creates a vacuum and so the air pulls the water up in the bent tube.
