In tall trees,the water column in the xylem does not break due to its weight because of:

How are water and ions absorbed in roots? Explain with a diagram.

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:

What is the force developed in the cortex of the root that pushes water from the soil into the xylem of the root?

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.

Assertion : Upward movement of water is called ascent of sap.
Reason : Upward movement of water occurs through xylem and phloem.
