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.

Detailed explanation-2: -Root hair cells are specialized epidermal cells that greatly increase the surface area of roots. As such, they are widely believed to play an important role in plant nutrition by facilitating the absorption of water and nutrients.

Detailed explanation-3: -Root hairs collect water and minerals that are present in the soil. They also increase the surface area for absorption.

Detailed explanation-4: -Roots possess hair-like projections called root hairs, which protrude from their surface. The root hairs aid the plant absorb more nutrients and water as they enhance the available surface area.

Detailed explanation-5: -Root Hairs They greatly increase the surface area of the root to provide a larger surface to absorb water and nutrients.
