WebOct 28, 2024 · A potometer is a device used for measuring the rate of water uptake of a leafy shoot. The reasons for water uptake are for photosynthesis and transpiration. Potometers are often difficult to set up, as measurement-altering air bubbles in the xylem of the plant or in the apparatus must be eliminated. WebHow does a potometer work GCSE? As water is transpired from the leaves, the shoot absorbs water from the potometer. The distance the air bubble moves in a certain period of time can be used to calculate the rate of water uptake. The apparatus is set up under water to prevent the entry of any unwanted air bubbles.
