According to one theory, in sunlight, the concentration of potassium ions (K+) increases in the guard cells. A Labeled Diagram of the Plant Cell and Functions of its Organelles. When the two guard cells are turgid (swollen with water), the stoma is open, and, when the two guard cells are flaccid, it is closed. guard cells have chloroplasts, and open and close the stoma. The width may vary from a few microns to 50 microns. The pore is formed by a pair of cells known as guard cells. Based on Plant Development.
