✒️ The word Plasmolysis was generally derived from a Latin and Greek word plasma – The mould and lusis – loosening.

✒️ Types of Plasmolysis :–

✏️ Concave Plasmolysis.

✏️ Convex Plasmolysis.

✒️ Conditions of Plasmolysis :–

✏️ Isotonic: External solution balances the osmotic pressure of the cytoplasm.

✏️ Hypotonic: External solution is more dillute than the cytoplasm (cell swells).

✏️ Hypertonic: External solution is more concentrated (cells shrink).

$\Huge{\orange{\underline{\textsf{Plasmolysis\::-}}}}$

$\boxdot\:$It it is defined as shrinkage of protoplasm or cytoplasm due to hypertonic solution. it is collectively called as plasmolysis.

$\boxdot\:$Plasmolysis takes place through exosmosis.

$\boxdot\:$Plasmolysis consist of incipient plasmolysis and total total plasmolysis. At initial stage shrinkage of cytoplasm start this phenomenon is known as incipient plasmolysis and if plasmolysis results into circular ring formation approx. This phenomenon is collectively known as total plasmolysis.

$\boxdot\:$In plasmolysis hypertonic solution is placed in between protoplasm and cell wall.

$\boxdot\:$Plasmolysis determines the living and nonliving cells.

$\boxdot\:$Plasmolysis has diverse significant which are :-

• In the preparation of pickles plasmolysis is involved.

• For the preservation of fishes and meat.
