Science IX B Types of Osmosis
When the Molecules of the Solvent Passes through a solution with low density/concentration to a solution of a higher density/concentration through a semi-permeable membrane
In Simple Words, A Special type of Diffusion.
Osmosis are of two types:
Endosmosis– When a substance is placed in a hypotonic solution, the solvent molecules move inside the cell and the cell becomes turgid or undergoes deplasmolysis. This is known as endosmosis.
(A hypotonic solution is the one that has a higher solute concentration inside the cell than outside.
Hypotonic: Less Solvent (amount) /More Solute (More water, Etc))
Exosmosis– When a substance is placed in a hypertonic solution, the solvent molecules move outside the cell and the cell becomes flaccid or undergoes plasmolysis. This is known as exosmosis.
(A hypertonic solution is one that has a higher solute concentration outside the cell than inside.
Hypertonic: More Solvent (amount) /Less Solute (Less Water, Etc))
Netural: An isotonic solution is one that has the same concentration of solutes both inside and outside the cell.
Isotonic: Same Solvent (amount) /Same Solute (Same Water, Etc)
