Detailed explanation-1: -A potometer is a device, which is used to measure water uptake by the plant shoot during transpiration. It is also known as transpirometer. Ganong’s potometer is used to measure the transpiration rate in a laboratory.
Detailed explanation-2: -A potometer or transpirometer is a device used to measure the rate of water uptake of a leafy shoot. The causes of water uptake are photosynthesis and transpiration. There are two main types of potometers the bubble potometer and the mass potometer.
Detailed explanation-3: -A simple potometer is a piece of capillary tubing to which a plant has been connected. The water uptake is measured by recording the time taken for a bubble in the tube to move a set distance. To find the rate of water uptake of a plant.
Detailed explanation-4: -A simple potometer comprises: a container of water. a capillary tube. rubber tubing to connect the capillary tube to the stem of the leafy shoot.
Detailed explanation-5: -The “Potetometer, ” an Instrument for Measuring the Transpiration of Water by Plants.
