The force by which water move upwards into tracheary elements of xylem in the root region is A) Transpiration pull B) Root pressure C) Turgor pressure D) Imbibition pressure
Option B) Root pressure is the force in root region that helps to drive water or sap upwards into tracheary elements of xylem. Water is absorbed through the root hairs from the soil. During low transpiration there is no transpiration pull that time root pressure increases and water moves upwards in xylem elements
