The potometer
Webb27 dec. 2024 · GCSE Biology Transport Systems Measuring Water Uptake. Under normal circumstances, the rate of transpiration can be measured by the uptake of water. This is because if water leaves the plant, then water is taken up the xylem. A potometer measures the rate of water uptake of a leafy shoot. It can be used to observe the rate of … WebbAnother type of potometer is the 'Mass Potometer' This consists of a plant shoot held securely in a sealed beaker. The bottom of the shoot must be in contact with the water. The whole device is weighed at fixed intervals. The loss in weight represents the water lost through transpiration and not specifically the water taken up by the shoot.
