Detailed explanation-1: -Root hairs are the small tubular extensions of the root surface which help in the absorption of water and minerals from the soil. It increases the surface area for absorption. More number of root hairs will increase the surface area and increase water absorption also.
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: -Their distinctive lateral elongation increases the surface of exchange between the plant’s root system and the soil. The main function of root hairs is the uptake of water and nutrients from the rhizosphere.
Detailed explanation-4: -Root hairs collect water and minerals that are present in the soil. They also increase the surface area for absorption.
Detailed explanation-5: -Root hairs collect water and mineral nutrients in the soil which is sent throughout the plant.
