The correct answer is:
amount of water absorbed equals the amount transpired
A potometer is a device, which is used to measure water uptake by shoot during transpiration. It is also known as transpirometer. The Ganong's potometer is used to measure the transpiration rate in a laboratory (Ref. to Fig. 27.5)
