Detailed explanation-1: -Root hair cells improve plant water absorption by increasing root surface area to volume ratio which allows the root hair cell to take in more water. The large vacuole inside root hair cells makes this intake much more efficient.
Detailed explanation-2: -Root hair absorbs water from soil through osmosis. Water will be absorbed by root hairs by osmosis as the environment in the soil is hypotonic. This kind of absorption takes place passively. The water can easily move from the region of higher concentration to the low concentration without expenditure of energy.
Detailed explanation-3: -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.
Detailed explanation-4: -Root hairs collect water and mineral nutrients in the soil which is sent throughout the plant.
