Comment on the experimental set-up.
(i) What does the set-up demonstrate?
(ii) What will happen to the level of water if a blower is placed close to set-up?
(iii) Will the mercury level fluctuate (go up/down) if phenyl mercuric acetate is sprayed on leaves?
(i) This set-up demonstrates transpiration pull.
(ii) Water will rise up due to activity of blowers the rate of transpiration increases
(iii) The mercury level goes down, if phenyl mercuric acetate is sprayed on the leaves. When
mercuric acid is sprayed on the leaves the stomata gets blocked and rate of transpiration decreases.
