Explain the types of osmosis.

Explanation

Types of osmosis : (i) Based on the direction of movement of water or solvent in an osmotic system two types of osmosis can occur they are Endosmosis and Exosmosis.
(ii) Endosmosis : Endosmosis is defined as the osmotic entry of solvent into a cell or a system when it is placed in a pure water or hypotonic solution. For example dry raisins (high solute and low solvent ) placed in the water , it swells up due to turgidity.
(iii) Exosmosis : Exosmosis is defined as the osmotic withdrawal of water from a cell or system when it is placed in a hypertonic solution. Exosmosis in a plant cell leads to plasmolysis.
