| Secretory cells either contain many small vacuoles or a single larger vacuole with flocculent contents and numerous vesicles. |
| The amount of contractile vacuoles can tailor in accordance with suctorian species, age and size. |
| The cytoplasm contains, in addition to digestive vacuoles, contractile vacuoles which probably function in the control of osmotic pressures. |
| The columnar or cuboidal biliary-type cells were pseudostratified and often contained mucin vacuoles. |
| In some simple organisms, such as amoeba, water is actively excreted from the cell in vacuoles. |
| The epithelial cells lining the cyst contained abundant mucin vacuoles that filled the cytoplasm of the luminal half of the cells. |
