WebbIt is invented by a scientist named Ganong and therefore, it is also known as Ganong's potometer. Working principle: The basic working principle is the amount of water absorbed by plants is equal to the amount of water that transpires in the form of water vapor. This is because the absorption of water-dependent on the transpiration pull. WebbThe whole apparatus is filled with water and the joints are made air tight. The apparatus is placed in the sunlight. Air bubble enters the tube and after this lower end of the tube is …

Porometer - an overview ScienceDirect Topics

Webb2 You must cut the shoots under water and you must assemble the potometer under water. This requires a large sink. If air gets into the xylem vessels of the plant, it can form air locks which will prevent the plant taking up water and so prevent steady transpiration. 3 The potometers should be left for the leaves to dry. WebbFig. 5.1. Principles of operation of three types of diffusion porometer: (a) non-aspirated or non-ventilated, (b) aspirated by a fan within the chamber and (c) aspirated by pushing air through a by-pass containing the sensor and back into the chamber. Aspirated porometers have a much lower boundary-layer resistance and this increases the ... solve 18-2w 4w

Principle of working of all potometers is - Toppr

WebbPotometer is the device used to measure the rate of transpiration. It works on the principle that the amount of water absorbed equals the amount transpired so it measures the amount of water absorbed. Test: Transpiration & Root Pressure - Question 6. Save.
