The vegetative plant vacuole occupies >90% of the volume in mature plant cells. Vacuoles play fundamental roles in adjusting cellular homeostasis and allowing cell growth. The composition of the vacuole and the regulation of its volume depend on the coordinated activities of the transporters and channels localized in the membrane (named tonoplast) surrounding the vacuole. While the ...

After plasmolysis the gap between the cell wall and the cell membrane in a plant cell is filled with hypertonic solution. This is because as the solution surrounding the cell is hypertonic, exosmosis takes place and the space between the cell wall and cytoplasm is filled with solutes, as most of the water drains away and hence the concentration inside the cell becomes more and becomes hypertonic. Importance of plasmolysis. Living cells show plasmolysis . It can, therefore, determine whether a cell is living or dead. The method of salting prevents the plants to grow in the cracks of the walls. This treatment causes plasmolysis in the root cells leading to the death of the plant. (plăz-mŏl′ĭ-sĭs) n. pl. plas·mol·y·ses (-sēz′) Shrinkage or contraction of the protoplasm away from the wall of a living plant or bacterial cell, caused by loss of water through osmosis. When a plant cell is placed in hypertonic solution, the plant cell loses water and hence it loses the turgor pressure. This makes the cell flaccid. The plant cells wilt in this condition. Further water loss results in plasmolysis. At this point, the pressure decreases to an extent where the protoplasm of the cell peels away from the cell wall.

In contrast, plant cells placed into a hypertonic solution shrivel as water exits, and the membrane pulls away from the cell wall. When the plasma membrane and cell wall separate (split) from one another, the effect is called plasmolysis . The initial stage of plasmolysis where the protoplasm just starts leaving the cell wall is called incipient plasmolysis. Reverse plasmolysis: When a completely plasmolysed cell is again placed in water or a hypotonic solution, endosmosis takes place and the protoplasm regains its original state and shape. i.e., the cell becomes fully turgid.
