Detailed explanation-1: -Water is absorbed by the root hair cells by a process called osmosis. The concentration of the water molecules in the soil is usually higher than it is inside the root hair cells. So water is absorbed by the root hair cells from outside.

Detailed explanation-2: -Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption. They also contain lots of mitochondria, which release energy from glucose during respiration in order to provide the energy needed for active transport.

Detailed explanation-3: -Maximum water absorption occurs via root hair cells only. Root hairs are long, thin, and can easily penetrate between tiny soil particles. Complete answer: Root hairs prevent bacterial entry in xylem sap. Root hairs cover a large surface area for water absorption.

Detailed explanation-4: -Complete answer:-Plants absorb water from the soil with the help of roots. It also absorbs minerals in organic form through root hairs. The water and minerals get transported by xylem vessels.
