... turgor pressure in the upper epidermal cells. Recent studies indicate that the pressure loss may be in the layer of mesophyll cells underlying the upper epidermis. When these cells suddenly become flaccid, the leaf ... . This is followed by a rapid shuttling of water molecules from parenchyma cells in one half of the pulvinus to cells in the other half. This action results in loss of turgor ...
