Tools, Techniques and Assessment in Biology: A Course ...
Using a potometer to investigate transpiration Introduction A potometer is an instrument which, strictly speaking, measures the uptake of water by a leafy shoot. However, of the volume of water taken up by a plant, only a very small percentage ...

Razor blade A potometer is a device for measuring the rate of water uptake by an isolated leafy shoot. The water in the xylem elements in the shoot is continuous with the water filling a capillary tube attached to its cut end. The rate at which a ...

Biology: A Functional Approach. Students' Manual - Halaman 120
Two types of potometer are illustrated in Figure 12.1. In both cases water uptake is measured by timing how long it takes for an air bubble to pass along the graduated capillary tube. Procedure SETTING UP THE POTOMETER Q Immerse the ...

Biology for AQA.: Separate award
Many of them use a piece of apparatus known as a potometer (Figure 3). A potometer can be used to show how the uptake of water by the plant changes with different conditions, giving a good idea of the amount of water lost by the plant in ...

Biology: A Modern Introduction - Halaman 89
A potometer was assembled, as shown in Figure 7.7. The time for a bubble to travel 50 mm along the capillary tube was found under the following conditions: plant leaves enclosed in a plastic bag (left for 30 minutes before readings taken), ...

Genetics Classical To Modern - Halaman 4-37
The instrument used to measure and/or compare the rate of transpiration is known as potometer. Many different types of potometers are available. These include simple potometer, Fanner's potometer, Ganong's potometer, Bose's potometer, ...
Measuring transpiration rates A potometer is used to measure transpiration rates (Fig 12.9). It contains a leafy shoot, the stem of which was cut and fixed into the potometer under water to stop any air entering its xylem vessels. All the joints are ...

Advanced Biology - Halaman 276
Measuring transpiration rates directly can be difficult, but they are often estimated using a simple potometer (figure 2). The potometer actually measures water uptake. Estimates of transpiration assume that the water lost by transpiration equals ...
