Question

What is the purpose of the reservoir in Ganong's potometer??

Answer 1

The reservoir in Ganong's potometer helps us to reset the bubbles and introduce them in the setup

Hope u have got your answer

Answer 2

Reservoir helps the air bubble to travel back to the start of the measuring scale when the experiment is repeated.

This also helps in determining :

● water absorbed by the plant

● transpiration rate in a plant

Photometer is a device which is solely used for the purpose to find out the rate of transpiration in a plant. But this device is not easy to set up because an air bubble in the xylem of the plant can prove to be really problematic in its setup.
