A Potometer is a device used for measuring the rate of water uptake of a leafy shoot. The causes of this water uptake are photosynthesis and transpiration. You measure the volume of water by calculating the rate of movement of the air bubbles and hence the rate of transpiration. Using the formula:
distance moved by air bubble/time take for the air bubble to move that distance.
The units of measurement are cm/s.
how do you measure the volume of water that is being transpired?
