Potometer practical method
Did you know?
WebA potometer provides an indirect measurement of the transpiration rate – it measures how fast water is absorbed, which is related to how fast water vapour is being lost. It cannot measure how fast water vapour is being given off directly. As the leafy twig transpires, the air bubble moves to towards the plant.
