Short / Long answer type questions .
Cell is called an osmotic system. Explain

Answer 1

A cell is an osmotic system. The net movement of the cell sap depends on the type of solution present in the surrounding.

If the osmotic concentration of the solution is less than that of the cell sap, the solution is called a hypotonic solution. This causes endosmosis and thus swelling of the cell takes place.

If the osmotic concentration of the solution is more than that of the cell sap, the solution is called hypertonic solution., This causes the exosmosis and thus the cell shrinks.

If the osmotic concentration of both the solution as well as the cell sap is same, no net movement takes place. No net change occurs in the cell.
