Introductory Crop Physiology

Exosmosis.

• If the plant cell is placed in hypertonic solution (whose OP is higher than cell sap) the water comes out of the cell sap into the outer solution and the cell becomes flaccid. This process is known as exosmosis.
• During the exosmosis, the cell membrane will be separated from the cell wall and this condition is called as plasmolysis. In the case of isotonic solution, cell (or) tissue will remain as such as there is no movement of water molecules..
