Which instrument is used to estimate the rate of transpiration in plants?

Answer and explanation

Correct answer: Potometer

Direct answer: B, potometer. A potometer is used to estimate the rate of transpiration by measuring the rate at which a leafy shoot takes up water. The water uptake is used as an indirect indicator because most of the water absorbed by a healthy shoot is lost through transpiration, although the instrument does not measure vapor loss from leaves directly. A barometer measures atmospheric pressure, so it cannot measure plant water uptake. A thermometer measures temperature. A hygrometer measures humidity in air. Therefore B is the only suitable choice. Memory cue: potometer begins with “poto,” associated with water uptake by a plant; remember that it estimates transpiration rather than measuring it perfectly and directly.
