When a plant wilts, sequence of events will be as

Options

A. Exosmosis, deplasmolysis, plasmolysis, temporary and permanent wilting
B. Exosmosis, plasmolysis, deplasmolysis, temporary and permanent wilting
C. Exosmosis, temporary and permanent wilting
D. None of the above

Answer

### Step-by-Step Solution

1. **Understanding Wilting**:
- Wilting occurs when a plant loses turgor pressure due to water loss. This can happen due to various factors such as heat, drought, or disease.

2. **Sequence of Events**:
- The sequence of events leading to wilting can be broken down as follows:
- **Exosmosis**: This is the process where water moves out of the plant cells into the surrounding environment. This typically occurs when the surrounding soil is dry, leading to a loss of water from the plant.
- **Plasmolysis**: Following exosmosis, the plant cells begin to shrink as they lose water. This process is called plasmolysis, where the cell membrane pulls away from the cell wall due to the loss of turgor pressure.
- **Wilting**: As a result of exosmosis and plasmolysis, the plant will start to wilt. This can be temporary if water is available again, or it can lead to permanent wilting if the water loss continues.

3. **Identifying the Correct Sequence**:
- The correct sequence of events when a plant wilts is:
1. Exosmosis
2. Plasmolysis
3. Temporary and Permanent Wilting

4. **Conclusion**:
- Based on the options provided, the correct answer is the second option: exosmosis, plasmolysis, temporary and permanent wilting.
