The following percentage of water absorbed by herbaceous plants is lost in transpiration

Options

A. 80
B. 60
C. 99
D. 40

Answer

To solve the question regarding the percentage of water absorbed by herbaceous plants that is lost in transpiration, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Transpiration**:
- Transpiration is the process by which plants lose water, primarily through small openings on their leaves called stomata. This process is crucial for maintaining water and nutrient flow within the plant.

2. **Water Absorption in Herbaceous Plants**:
- Herbaceous plants are non-woody plants that typically have a high surface area for transpiration. They absorb water mainly through their roots.

3. **Percentage of Water Lost**:
- Studies indicate that a significant percentage of the water absorbed by these plants is lost through transpiration.

4. **Analyzing the Options**:
- The options given are 80%, 60%, 99%, and 40%.

5. **Identifying the Correct Percentage**:
- Research and studies show that approximately 99% of the water absorbed by herbaceous plants is lost through transpiration. This is a well-documented figure in plant physiology.

6. **Conclusion**:
- Therefore, the correct answer to the question is 99%.

### Final Answer:
The percentage of water absorbed by herbaceous plants that is lost in transpiration is **99%**.
