The movement of ions into the 'free space' or 'outer space' of the cell without the expenditure of metabolic energy is known as:
Show answer and explanation
Correct answer: Active ion uptake into vascular tissues drawing water by osmosis
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.
