The continuous excretion of watery substance from the stump of a well-watered pot plant after cutting off the shoot slightly above the base is due to:

Which two statements are wrong for transpiration pull theory?
$(i)$ There is a continuous network of water channels from the root hairs to the tips of the leaves.
$(ii)$ Due to adhesive force between molecules of water,the water column has a great tensile strength.
$(iii)$ There is a cohesive force between the wall of the xylem vessels and water.
$(iv)$ Transpiration pull is strong enough to pull up the column of water to a great height.

Will the ascent of sap be possible without the cohesion and adhesion of the water molecules? Explain.

$A$ mutant plant is unable to produce materials or precursors that form the Casparian strip. This plant would be:
