उत्तर
Deplasmolysis occurs when a plasmolysed cell is placed in Tap water.
Explanation:
One hypotonic solution is tap water. Because the concentration of water outside the cell is higher, water moves within the cell. Subsequently, the cell expands and turns turgid. This is known as deplasmolysis.

The figure given below is a diagrammatic representation of a part of the cross-section of the root in the root hair zone. Study the same and then answer the questions that follow:
- The parts labelled as 1, 2, 3 and 4 are:
- Root hair, Xylem vessel, Soil particles, Cortex respectively.
- Xylem vessel, Soil particles, Root hair, Cortex respectively.

- Active transport
- Osmosis
- Passive absorption
- The kind of force which exists between a liquid and any surface is called as:
