Explanation:
Detailed explanation-1: -Turgor pressure is key to the plant’s vital processes. It makes the plant cell stiff and rigid. Without it, the plant cell becomes flaccid. Prolonged flaccidity could lead to the wilting of plants.
Detailed explanation-2: -Leaf turgor pressure in hydrated leaves (∼0.6 megapascal) decreased to zero upon wilting.
Detailed explanation-3: -Leaf dehydration decreases water potential and cell turgor pressure. Therefore, changes in cell turgor pressure may regulate water transport across plant cell membranes.
