what is osmosis what is osomis
Answers
Answer:
Osmosis is the spontaneous net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides.
Explanation:
What is Osmosis?
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.
Osmotic Solutions:
There are three different types of solutions:
1.Isotonic Solution
2.Hypertonic Solution
3.Hypotonic Solution
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.
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.
