Lose of water from tips of leaves is

Options

A. Transpiration
B. Guttation
C. Bleeding
D. Respiration

Answer

To solve the question "Loss of water from tips of leaves is", we need to analyze the given options one by one.

### Step-by-Step Solution:

1. **Identify the Options**: The options provided are:
- A) Transpiration
- B) Gutation
- C) Bleeding
- D) Respiration

2. **Define Transpiration**:
- Transpiration is the process of water vapor loss from the aerial parts of the plant, primarily through the stomata in leaves. It is a crucial process for water regulation and nutrient transport in plants.

3. **Define Gutation**:
- Gutation is the process where water is expelled from the tips or edges of leaves in the form of droplets. This occurs through specialized pores called hydathodes, usually under conditions of high humidity or when the soil moisture is high.

4. **Define Bleeding**:
- Bleeding, or exudation, refers to the loss of fluids from the plant due to injury or damage. This fluid can be sap or other substances and is not specifically related to water loss from leaves.

5. **Define Respiration**:
- Respiration is a metabolic process where plants convert glucose and oxygen into energy (ATP), releasing carbon dioxide and water as by-products. It does not involve the loss of water from leaves.

6. **Determine the Correct Answer**:
- Based on the definitions, the loss of water from the tips of leaves is specifically described by gutation, as it involves the expulsion of water droplets from the leaf tips through hydathodes.

### Conclusion:
The correct answer to the question "Loss of water from tips of leaves is" is **B) Gutation**.
