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:
If bottle 'C' was fitted with a 3-holed rubber stopper and a thermometer was introduced in such a way that its bulb reaches close to the germinating seeds, what would you observe? Why?
उत्तर
By introducing a thermometer in bottle 'C', the change in temperature is checked or observed. If respiration takes place, there will be a rise in temperature and if there is no rise in temperature, no respiration occurs. Therefore, a three-holed rubber stopper and a thermometer were introduced.
