In the process of ascent of sap, the water and dissolved minerals absorbed by the root system of plants are transported towards which direction?

Water molecules are highly polar. The polar end of a molecule attracts opposite charges on another water molecule (acting like a magnet). How would you explain this property of water with reference to the upward movement of water? Comment on the upward movement of water given the intermolecular hydrogen bonding in water.

Which of the following processes is important for the transportation of water from root to leaf?

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.

The plant undergoes wilting when

$A$ botanist discovered a mutant plant that was unable to produce materials that form the $Casparian$ strip. This plant would be:
