WebThe interior of the cell contains cytoplasm, a jelly-like fluid substance. Toward the posterior of the cell is a star-like structure, the . contractile vacuole. This organelle helps the cell . remove excess water. Without it, the euglena could take in so much water via osmosis that the cell would burst. WebThe first region is where the excess water enters through the pores due to osmosis. The swelling process takes place and eventually the structure of contractile vacuole is dissociated. The contractile vacuole moves to the edge of the cell and thus bursts out and expel the excess/ surplus water and the cycle repeats back. Webowing to the excess of total ions within the cell. The cell will swell indefinitely. Figure 3b depicts the opposite case. There is now no fixed anion, but a pump ensures that sodium ions are kept out of the cell, bringing about an excess of fixed cation outside the cell and hence a Donnan potential.
