Temporary wilting is due to

Options

A. Photosynthesis
B. Transpiration
C. Respiration
D. Absortion of water

Answer

### Step-by-Step Solution:

1. **Understanding Temporary Wilting**:
- Temporary wilting refers to a short-term loss of turgidity in plant cells. Turgidity is the state of being swollen or firm due to the presence of water in the vacuoles of plant cells.

2. **Identifying the Cause**:
- The question asks for the cause of temporary wilting. The options provided are:
- A) Photosynthesis
- B) Transpiration
- C) Respiration
- D) Absorption of water

3. **Analyzing the Options**:
- **Photosynthesis**: This process involves the conversion of light energy into chemical energy (food) and does not directly cause wilting.
- **Transpiration**: This is the process where water vapor is lost from the plant, primarily through stomata in the leaves. If the rate of transpiration exceeds the rate of water absorption from the soil, it can lead to temporary wilting.
- **Respiration**: This process involves breaking down glucose for energy and is not directly related to wilting.
- **Absorption of Water**: While this is essential for maintaining turgidity, if the absorption rate is low compared to transpiration, it will not prevent wilting.

4. **Conclusion**:
- Since temporary wilting occurs when the rate of transpiration is greater than the rate of water absorption, the correct answer is **B) Transpiration**.
