Detailed explanation-1: -Under normal circumstances, the rate of water uptake gives a measure of the rate of transpiration. 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.
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 potometer’ (from Greek = drunken, and = measure), sometimes known as transpirometer, is a device used for measuring the rate of water uptake of a leafy shoot which is almost equal to the water lost through transpiration. The causes of water uptake are photosynthesis and transpiration.
