The correct answer is: A change in the turgidity of the guard cells
The immediate cause of the opening or closing of stomata is a change in the turgidity of the guard cells. The increase in turgidity within the guard cells leads to the opening of the stomata, and the loss of turgor causes the stomata to close.
