In a hair root cell what absorbs water

WebRoot hairs function as tiny osmotic systems. Each root hair has a thin permeable cell wall, a semipermeable cytoplasm and an osmotically active cell sap present in the central vacuole. Because of the latter a root hair cell has a water potential of -3 to -8 bars. Water potential of the soil water is -.1 to – .3 bars.
