Detailed explanation-1: -The potometer does not measure the rate of transpiration accurately because not all of the water that is taken by the plant is used for transpiration (water taken might be used for photosynthesis or by the cells to maintain turgidity). The potometer measures the rate of uptake of water.
Detailed explanation-2: -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-3: -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-4: -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-5: -Potometer. A potometer can be used to measure the rate of transpiration that’s proportional to water uptake.
