What is the primary cause of 'Root Pressure' in plants?
Show answer and explanation
Correct answer: Active absorption of ions into the vascular tissues followed by water
As various ions from the soil are actively transported into the vascular tissues of the roots, water follows (its potential gradient) and increases the pressure inside the xylem. This positive pressure is called root pressure.
