Question

What is osmosis?? Hlo guys..​

Answer 1

$\huge \sf{ \underline{Answer :-}}$

Osmosis is a passive process and happens without any expenditure of energy. It involves the movement of molecules from a region of higher concentration to lower concentration until the concentrations become equal on either side of the membrane.

Any solvent can undergo the process of osmosis including gases and supercritical liquids.

There are three different types of solutions:

Isotonic Solution.

• An isotonic solution is one that has the same concentration of solutes both inside and outside the cell.

Hypertonic Solution.

• A hypertonic solution is one that has a higher solute concentration outside the cell than inside.

Hypotonic Solution.

• A hypotonic solution is the one that has a higher solute concentration inside the cell than outside.

Osmosis is 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.

• 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.
