Detailed explanation-1: -Osmosis helps plants to absorb water and minerals from the soil. Q. The essential functions of roots are anchorage and absorption of water and minerals in the terrestrial plant.

Detailed explanation-2: -Water moves from the soil to the roots, stems, and ultimately the leaves, where transpiration occurs. The roots absorb enough water to compensate for water lost to transpiration. Rapid absorption is aided by root hairs, which extend from epidermal cells, increasing surface area (Figure 17.1.

Detailed explanation-3: -Water is constantly being absorbed by the roots due to the negative water potential in the root cells. This movement of water into the roots can cause the water pressure inside the roots to become high, resulting in a force that ‘pushes’ water up the stem xylem.
