How much of absorbed water is lost during transpiration in a plant?

Options

A. `90%`
B. `98-99%`
C. `99.9%`
D. `90-95%`

Answer

**Step-by-Step Solution:**

1. **Understanding Transpiration**: Transpiration is the process through which plants lose water in the form of vapor. This primarily occurs through small openings on the leaves called stomata.

2. **Water Absorption**: Plants absorb water from the soil through their roots. This absorbed water is essential for various physiological processes within the plant.

3. **Percentage of Water Lost**: Research and estimates indicate that a significant portion of the water absorbed by plants is lost through transpiration.

4. **Estimation of Water Loss**: It is estimated that around 90-99% of the absorbed water is lost during transpiration. More specifically, the most commonly cited figure is that approximately 98-99% of the absorbed water is lost.

5. **Conclusion**: Therefore, the correct answer to the question is that **98-99% of absorbed water is lost during transpiration in a plant**.
