Which instrument is used to measure the rate of transpiration by measuring the amount of water absorbed?
Show answer and explanation
Correct answer: Potometer
A potometer (such as Ganong's potometer) measures the rate of water uptake by a plant shoot. Since almost all water absorbed is transpired, it is a reliable tool for estimating transpiration rates.
