It moves through the osmosis of water in individual cells. Some become more
filled with water and others less filled and this puts pressure in different
places in the plant. This is controlled by hormones in the plant.
The cells that are responsible for the movement of this plant are govern by
a chemical reaction and a series of rapid water movement in and out of
cells. The same mechanism that keeps celery crisp. Water balloons the
cells to a rigid condition and when the water leaves the cell the cell
becomes limp. Much like wilting of a plant. If you want a more technical
term, it would be osmosis and osmotic pressure differences.
