Water will be absorbed by root hair when: - BYJU

WebWater enters the root hair cells by osmosis. This happens because soil water has a higher water potential than the cytoplasm of the root hair cell. Minerals enter by active transport. WebMay 4, 2024 · 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 17.1.4. 1 ).
