Experiments on Stomata and Transpiration: 12 Experiments

WebTranspiration can be described as the loss of water from a plant into the atmosphere, through evaporation from the leaves. Water evaporates from tiny pores in the epidermis of leaves called stomata. These pores have special structures that enable them to be either open or closed, depending on certain conditions. Definition: Transpiration WebThe rate of transpiration can be estimated in two ways: Indirectly - by measuring the distance the water level drops in the graduated tube over a measured length of time.

WebThe difference between the two weighings is a measure of the amount of water lost from the leaf surfaces. As the areas are the same, this is also a quantitative measure of the differential rates of transpiration from the two surfaces. Experiment # IX. Measurement of Transpiration Rates—Quantitative: Nearly fill a 500-ml conical flask with water. WebOccasionally, researchers learning how to measure leaf transpiration ask us if they can estimate the transpiration from a single leaf by simply measuring its stomatal conductance. Unfortunately, the answer is no. This article illustrates why that’s true and what you’ll need to do to estimate the total conductance, and therefore, the
