Give demonstration of endosmosis and exusmosis

Endosmosis

Exosmosis

(Endo = inside)

The solvent moves out of the cell.

(Exo = outside)

Osmosis towards the inside of a cell.

Occurs when there is lower osmotic pressure.

Occurs when the osmotic pressure is higher.

Hypotonic solutions induce endosmosis in <a href="https://byjus.com/biology/cells/">cells </a>(distilled water is hypotonic because it contains no solute).

Hypertonic solutions induce exosmosis in cells (Intravenous Fluid is often hypertonic as it has many solutes).

Higher water potential of the surrounding areas when compared to the cytosol (the watery part of cytoplasm in a cell).

Lower water potential of the surrounding areas when compared to the cytosol.

As a result, the cell swells.

As a result, the cell shrinks.

Example: Raisins swell when placed in normal water.

Example: Raisins shrivel when placed in the concentrated salt solution.
