उत्तर
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.
