$III$. Abscisic acid $(ABA)$ affects the mechanism of opening and closing of stomata.
$IV$. Starch of guard cells is converted into $PEP$ (phosphoenolpyruvate) ions by the process of hydrolysis.
$V$. Potometer works on the principle of potential difference between the tip of the tube and that of the plant.
$VI$. Transpiration rate is directly proportional to the relative humidity.

$A$ twig kept in water having some salt remains fresh for a longer period due to

What will be the effect of water deficit (in soil) on the rate of transpiration?

Both evaporation and transpiration involve the loss of water in vapor form. However,they are different because.......
