explain the process of osomis in details
Answers
Answer:
Osmosis is a process which occurs when there is a difference in solute concentration between two solutions separated by a semipermeable membrane. A semipermeable membrane allows passage of water but not of solutes. The passage of water occurs because of a pressure difference of water between the two solutions.
Explanation:
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.
Osmotic Solutions
There are three different types of solutions:
Isotonic Solution
Hypertonic Solution
Hypotonic Solution
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.
Osmotic Pressure
Osmotic pressure is the pressure required to stop water from diffusing through a membrane by osmosis. It is determined by the concentration of the solute
