Q. The experimental set up shown in the adjacent diagram is for
A) The demonstration of development of suction force due to transpiration
B) Measuring the rate of transpiration
C) The demonstration of ascent of sap
D) The demonstration of anaerobic respiration
Explanation
The experimental set up shown in the diagram is simple potometer used for measuring the rate of transpiration. In simple potometer, when water is lost by the plant, it is taken from the glass tube and as a result, the mercury column rises.
