The answer would be ions
The gradient of ion concentration from intracellular compared to the extracellular will determine the resting potential of the cells. The movement of the ion itself will induce the action potential in nerve cells. Natrium/sodium and Kalium/Potassium ion have a big role in this mechanism.
The cell surface membranes of cells of flower, though semi-permeable, allows water to pass through cell via aqua proteins embedded in the membrane.
This is true since water goes from inside of cell to the extracellular environment when water potential inside the cell is higher than water potential outside the cell via process of osmosis (water goes from an area of high water potential down a concentration gradient to an area of low water potential). Cells in the flower became plasmolysed (cell surface membranes tear away from the cell walls) as the volume of water in cell decreases.
Hope this helps! :)
