What is the apparatus shown below .State it's purpose
State the use of
1.capillary tube
2.scale
3.water reservoir
What happen to movement of air bubbles the apparatus is kept under the following conditions
1.in sunlight
2.in the dark
3.in front of a fan
(a) = Ganong potometer.
To measure water up take during transpiration.
(b) 1 = It is done by lifting the bent capillary tube above the coloured water so that air may be sucked in due to suction pull and is again dipped into water.
2 = To measure water uptake during transpiration.
3 = It help in pushing back the bubble by releasing water to resart the experiment.
