Water is taken up by the root hair by osmosis. It can happen by active and passive absorption.
Explanation:
The root hairs are hydrophilic structures which actively absorb water present in soil. Water can be absorbed by two modes, that is active and passive absorption.
The theory of active osmotic absorption in plants was proposed by Atkins in 1916 and by Priestly in 1923.
Root hairs are extended structures of roots to facilitate increased water absorption from the surface area present.
Root cells act as active osmotic pressure systems, xylem absorbs water. Absorption happens by concentration gradient in the presence of capillary action for the water to be pulled up and supplied throughout the plant. The water is then used during photosynthesis to produce energy.
