A crushed (semi-circular) tannin vacuole is observable in the motor cell of the Mimosa main pulvinus immediately after stimulation. If the motor cell is then soaked in tap water for 15 to 20 minutes, the tannin vacuole begins to take a spherical shape. Before stimulation, using anesthetized material, spherical tannin vacuoles are observable.
In the presence of 0.01 M EDTA, the recovery of the tannin vacuole is accompanied by an increase in volume and surface area. But in the presence of CaCl2, the recovery process of the tannin vacuole scarcely is accompanied by changes in its volume and surface area. In the medium containing CaCl2 the recovery to a spherical shape is made by 15 to 25 minutes, while in the medium containing KCl it takes 30 to 40 minutes.
