Water lost by transpiration is

Options

A. pure water
B. rich in dissolved salts
C. rich in dissolved minerals
D. none of the above .

Answer

**Step-by-Step Solution:**

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

2. **Water Absorption and Transport**:
- Water is absorbed by the roots from the soil and transported to the leaves through specialized tissues known as xylem. The xylem plays a crucial role in moving water from the roots to the leaves.

3. **Water Loss Mechanism**:
- In the leaves, water vapor escapes into the atmosphere through the stomata. This process contributes significantly to the moisture in the atmosphere.

4. **Nature of Water Lost**:
- The water that is lost through transpiration is essentially pure water. It does not contain significant amounts of dissolved salts or minerals because these substances are retained in the plant for its physiological needs.

5. **Conclusion**:
- Based on the above points, the correct answer to the question "Water lost by transpiration is" is **pure water**.

**Final Answer**: Water lost by transpiration is **pure water**.
