The vacuole in stomatal cells of Allium undergoes major changes in shape during differentiation, switching from a globular form in new guard mother cells to a network of interconnected tubules and chambers, and then back to a globular form as guard cells mature. In addition, vacuolar network elements exhibit characteristic movements and rearrangements.
