Detailed explanation-1: -Investigating transpiration 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: -Potometer is an apparatus that is used for the measurement of transpiration. It measures the rate of water update which is equal to the rate of water lost through tranpiration. It is also known as a transpirometer.
Detailed explanation-3: -Potometer. A potometer can be used to measure the rate of transpiration that’s proportional to water uptake.
Detailed explanation-4: -The instrument used for measuring the rate of transpiration is called a potometer.
