Question

Exosmosis tends to cause the shrinkage of the cell whereas endosmosis tends to swells up the cell.

• A. True
• B. False

Answer 1

The correct option is A True

Exosmosis and endosmosis:

1. These are the two types of osmosis that depend on the concentration of solution and direction of flow of solvent from the cell sap.
2. When a cell is placed in a hypotonic solution the water molecules move inside the cell which is called endosmosis.
3. When a cell is placed in a hypertonic solution the water molecules ooze out of the cell which is called exosmosis.
4. Endosmosis results in turgidity of the cell as water molecules move inside the cell causing the cell to swell up.
5. Exosmosis results in flaccidity of the cell as water molecules move out of the cell causing the cell to shrink and become flaccid.

Final answer: The given statement is true.
