Answer

### Step-by-Step Solution to the Question: What shall be the sequence of events during wilting of a plant?

1. **Understanding Wilting**:
- Wilting is the process where a plant loses its rigidity and becomes limp. This typically occurs when the plant does not have enough water.

2. **Exosmosis**:
- The first event in the wilting process is exosmosis, which is the movement of water from inside the plant cells to the outside environment. This occurs when the plant is in a state of water deficit.

3. **Plasmolysis**:
- Following exosmosis, plasmolysis occurs. This is the phenomenon where the protoplasm (the living part of the cell) pulls away from the cell wall due to the loss of water. This shrinkage leads to the drooping of leaves.

4. **Temporary Wilting**:
- As the cells lose water and plasmolysis occurs, the plant may initially experience temporary wilting. This means that the plant can recover if it is re-watered soon enough.

5. **Permanent Wilting**:
- If the water deficit continues and the plant does not receive water, it may enter a state of permanent wilting. In this state, the plant cannot recover even if water is provided later, and it may eventually die.

### Final Sequence of Events:
- Exosmosis → Plasmolysis → Temporary Wilting → Permanent Wilting

### Answer:
The correct sequence of events during wilting of a plant is: **Exosmosis, Plasmolysis, Temporary Wilting, Permanent Wilting**.
