Question

Experiment to prove that carbon dioxide is produced during respiration in germinating seeds if seeds are not kept moist during experiment

Answer 1

The rise in the level of water indicates that CO2 is produced by germinating seeds during respiration. Actually, thegerminating seeds respire andproduce CO2, which is absorbed byKOH solution. This creates a vacuum in the conical flask. The air present in the bent glass tube moves into the conical flask.
