Give two examples
The two examples of turgor movements in plants are:
1. The rapid dropping of the leaves of the touch-me-not plant (Mimosa pudica) where if one of the leaves is touched, the leaflet folds up and the entire leaf droops. In these plants, the stimulus of touch leads to the loss of turgor at the base of the leaflets and consecutively the base of the petioles.
2. The sun facilitates the suction pull of water from the soil thus keeping the cells turgid in the morning by transpiration but soon the leaves wilt due to loss of turgidity during the night. Thus some plants show sleep movements at night due to the loss of turgor pressure.
