Water lost in guttation is

Options

A. Pure water
B. Impure water
C. In the form of vapour from
D. Either ( pure water ) or (Impure water )

Answer

To solve the question regarding the nature of water lost in guttation, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Guttation**:
- Guttation is the process by which plants lose water in the form of liquid droplets. This occurs primarily at night when the soil moisture is high and the transpiration rate is low.

**Hint**: Remember that guttation involves the loss of water as droplets, not vapor.

2. **Identifying the Structures Involved**:
- The water droplets in guttation are expelled through specialized pores known as hydathodes, which are located at the edges of leaves.

**Hint**: Hydathodes are key structures for guttation; think about where they are found on the plant.

3. **Analyzing the Composition of Guttation Water**:
- The water lost during guttation is not pure. It contains both organic and inorganic substances dissolved in it, making it impure.

**Hint**: Consider what substances might be present in the water that plants take up from the soil.

4. **Differentiating Guttation from Transpiration**:
- It's important to differentiate guttation from transpiration. Transpiration is the loss of water in the form of vapor and is generally considered to be pure water because it primarily consists of water molecules without dissolved substances.

**Hint**: Recall that transpiration occurs through stomata and involves water vapor, while guttation involves liquid droplets.

5. **Conclusion**:
- Based on the analysis, the water lost in guttation is classified as impure water due to the presence of various dissolved substances.

**Hint**: The correct answer to the question is that water lost in guttation is impure water.

### Final Answer:
Water lost in guttation is impure water.
