example osmosis with an example
Answers
Answer:
An example of osmosis occurs when a sugar solution and water, top, are separated by a semipermeable membrane. The solution's large sugar molecules cannot pass through the membrane into the water. Small water molecules move through the membrane until equilibrium is established, bottom.
⭐️ 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.
Example - The absorption of water from the soil is due to osmosis.
⭐️Osmotic Solutions
An Isotonic solution is one that has the same concentration of solutes both inside and outside the cell.
A Hypertonic solution is one that has a higher solute concentration outside the cell than inside.
A Hypotonic solution is the one that has a higher solute concentration inside the cell than outside.
⭐️Types of Osmosis
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.
