Question

Describe how root hair helps in the absorption of water from the soil

Answer 1

Dear student,
Roots have numerous root hairs that increase the surface area for the absorption of water and minerals. These root hairs are in contact with the water present in the soil. Water enters the cells of the root hair by the process of osmosis. Osmosis is the movement of water from a region of higher concentration to a region of lower concentration through a semi-permeable membrane. Hence, they perform the function of absorption.
