Question
Write any two limitations of using a Ganong's potometer to demonstrate the uptake of water.
Solution
The limitations of using Ganong's potometer to demonstrate the uptake of water are:
- One of the biggest disadvantages is that correctly setting up and calibrating can take some time and effort, which can be inconvenient if you need to gather data rapidly.
- Because the potometer relies on the plant's water intake to measure transpiration, variations in soil moisture or root pressure can skew your results.
- Air bubbles in the tubing or leaks in the system can potentially interfere with your measurements.

The apparatus shown in the following diagram is Garreau’s potometer designed to demonstrate unequal transpiration from the two surfaces of a dorsiventral leaf Before keeping the leaf in between the cups, anhydrous calcium chloride (CaCl2) contained in two small vials were weighed and placed in both the cups. The ends of the cups were closed with corks through which two mercury manometers were connected. After few hours, CaCl2 vials were taken out and weighed again.
What is the purpose of keeping CaCl2 vials inside the cup?
The apparatus used to measure the rate of transpiration is ______.
