Loss of water in its liquid phase from the margin of leaves is called

Options

A. Guttation
B. Cuticular transpiration
C. Lenticular transpiration
D. Root pressure

Answer

To solve the question, "Loss of water in its liquid phase from the margin of leaves is called," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the specific term that describes the loss of water in liquid form from the edges of leaves.

2. **Identifying Key Terms**: The key terms here are "loss of water," "liquid phase," and "margin of leaves."

3. **Exploring the Options**:
- **Guttation**: This refers to the process where water is expelled from the leaves in the form of liquid droplets. It occurs through specialized structures called hydrothodes, which are located at the margins or tips of leaves.
- **Cuticular Transpiration**: This is the loss of water vapor through the cuticle, which is a protective layer on the leaves, not in liquid form.
- **Lenticular Transpiration**: This refers to the loss of water vapor through lenticels, which are small openings in the bark of woody plants, also not in liquid form.
- **Root Pressure**: This is the pressure generated in the roots that helps in the upward movement of water, but it does not refer to the loss of water from leaves.

4. **Analyzing the Options**:
- Guttation is the only process that involves the loss of water in liquid form from the leaves.
- The other options (cuticular transpiration, lenticular transpiration, and root pressure) do not describe the loss of water in liquid form from the margins of leaves.

5. **Conclusion**: Based on the analysis, the correct answer to the question is **Guttation**.

### Final Answer:
**Guttation**
