Ions having high concentration in cell sap
WebNa + /K + -ATPase activity is exquisitely sensitive to intracellular sodium concentrations; in cortical tubules, the early Na + /K + -ATPase response to aldosterone is blocked by amiloride, suggesting that the increased activity is secondary to the sodium influx at the apical membrane. WebSolutions. ( 1) If the cell sap of the root hair cells contain high concentration of ions, will create an osmotic gradient resulting in endosmosis and conduction of water from the root …
