Question

Absorption of minerals by the epidermal cells of root and root hair causes the water to enter from surrounding soil into roots. It further reaches the root xylem. Thus, due to a continuous uptake of water by root cells, a water pressure is created in the root xylem. This pressure is called as________

• A. Osmotic pressure
• B. Root pressure
• C. Turgor pressure
• D. Wall pressure

Answer 1

The correct option is B

Root pressure

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.
