Answer 2

Answer:

Amount of water absorbed equals the amount transpired.

Explanation:

• Potometer is an instrument  or apparatus  with the help of which, rate of transpiration can be measured.
• Main types of potometers are as under: Simple potometer, Farmer’s potometer and Ganong’s potometer.
• The whole instrument is made of glass and consists of a  long tube, having a  side tube, bent  at right angles.  
• A  fresh  plant shoot  is  cut  under  water and  is inserted into the side tube through a cork, fitted into the mouth of this tube.
• The whole apparatus is filled with water and the  joints are made  air  tight.
• The apparatus is placed in the sunlight.
• Air bubble enters the tube and after  this  lower  end  of  the  tube  is  placed  in  the  beaker, containing water.
• Water is absorbed by the shoot and is transpired through the leaves.
• Transpiration pull is created and the air bubble begins to move alongwith the transpiration pull.
• Readings are taken for the air bubble and thus amount of water absorbed and transpired is calculated.
