Answer:

Here is your answer

It is observed that water rises in the tube. The rise in the level of water is due to a partial vacuum created in the flask because the gas produced during respiration is absorbed by KOH. This shows that germinating seeds produce CO2 during aerobic respiration as KOH can absorb CO2.
