Question

What happens to carbon dioxide that is given out by germinating seeds while performing the respiration experiment?

Solution

Carbon dioxide given by germinating seeds is absorbed by Potassium hydroxide during respiration experiment. This creates a vacuum in the conical flask. The air present in the bent glass tube moves into the conical flask.
