Turgidity – keeps cells firm and plants upright. Growth – supports height increase, new leaves, and root development. Solvent – dissolves chemicals inside the plant for metabolic processes. Cooling – regulates plant temperature. Transport – moves nutrients and dissolved substances throughout the plant. How To Know When Plants Need Water The most obvious sign of water stress is wilting — when non‑woody parts lose rigidity and droop. But waiting until wilting occurs can permanent...
