Apparatus used for measuring the rate of water uptake of a leafy shoot. The causes of water uptake are photosynthesis and transpiration. For demonstration of transpiration rates and rates of water absorption by a cut shoot under various external conditions. A plant shoot is sealed into a stopper which fits the end tube and whole apparatus is filled with water, the open end of the capillary tube, which is graduated in millimeter, dipping into beaker of water. The position of the air bubble may easily be adjusted by opening the glass stopcock to admit water from the reservoir.
