Intercalated Cells. This type cell is found in the late distal tubule and is represented by the IC box. Its main function is acid-base balance. The basolateral border of this cell is freely permeable to hydrogen and potassium.
For example, vacuoles in stomata cells contain large numbers of potassium ions, which can be pumped in or out to open or close the stomata. Animal Cells In animal cells, vacuoles serve more subordinate roles, such as assisting in endo- and exocytosis or basic storage of food and waste. Central Vacuole The central vacuole is found only in plant cells. It is filled with water and is pressurised, like a balloon. This forces all the other organelles within the cell out toward the cell wall. This pressure is called turgor pressure and is what gives plants their crisp and firm structure.
