प्रश्न
In order to study and prove a particular physiological process in plants, the following experiment was set up. Study the same and then answer the question that follow:
What change would you expect to observe in bottle 'D'?
उत्तर
The bottle 'D' having limewater will show that CO2 is produced due to respiration taking place in bottle 'C' having germinating seeds in it. Due to the CO2 produced in bottle C, the limewater turns milky, which passes through bottle 'D'.
