उत्तर
The rate of transpiration is determined with a/an potometer.
Explanation:
A potometer (such as Ganong’s potometer) is a specialised laboratory instrument used to measure the rate of water uptake by a leafy shoot, which is directly proportional to the rate of transpiration. It functions by tracking the movement of a tiny air bubble along a graduated capillary tube as the plant transpires and draws water. In contrast, evaporimeters and atmometers measure overall evaporation from open surfaces, while a perimeter is used in ophthalmology to test visual fields.
