Detailed explanation-1: -Roots have hairlike projections called root hairs protruding from their surface. These root hairs help the plant absorb more nutrients and water because they increase the available surface area.
Detailed explanation-2: -Root hair cells have long projections that increase the surface area that the plant can use to absorb water and minerals.
Detailed explanation-3: -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. Through the root hairs, the roots of many plants possess a mycorrhizal relationship with the fungi for greater absorption.
Detailed explanation-4: -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-5: -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.
