Comment on the experimental setup.
(a) What does the setup demonstrate?
(b) What will happen to the level of water if a blower is placed close to setup.
(c) Will the mercury level fluctuate (go up/ down) if phenyl mercuric acetate is sprayed on leaves?
Answer
(a) The changes in the process of transpiration due to fluctuation in the wind speed are demonstrated
(b) If the blower is closer, the wind speed will increase thus lowering the level of water and subsequently increasing the speed of transpiration.
(c) Mercury level would decrease if phenyl mercuric is spayed as it will lower the speed of transpiration.
