Options

A. It occurs in liquid form
B. It occurs in vapour from
C. It occurs during day time
D. It is controlled by stomata

Answer

To understand how guttation differs from transpiration, we can break down the characteristics of each process step by step.

### Step-by-Step Solution:

1. **Definition of Guttation**:
- Guttation is the process by which water is exuded from the plant in the form of liquid droplets. This typically occurs at night or early morning when the humidity is high and transpiration rates are low.

2. **Definition of Transpiration**:
- Transpiration is the process of water vapor loss from the plant, primarily through small openings called stomata. This process usually occurs during the day when the stomata are open to facilitate gas exchange.

3. **Form of Water Loss**:
- **Guttation**: Water is lost in the form of liquid droplets.
- **Transpiration**: Water is lost in the form of vapor.

4. **Pores Involved**:
- **Guttation**: The loss of water occurs through specialized structures called hydathodes.
- **Transpiration**: The loss of water occurs through stomata.

5. **Time of Occurrence**:
- **Guttation**: Typically occurs during the night or early morning when transpiration is minimal.
- **Transpiration**: Primarily occurs during the day when stomata are open.

6. **Composition of Water Lost**:
- **Guttation**: The water lost can contain dissolved organic and inorganic substances, making it impure.
- **Transpiration**: The water lost is generally pure, as it is mostly free of solutes.

### Summary of Differences:
- **Form of Water**: Guttation (liquid droplets) vs. Transpiration (water vapor).
- **Pores**: Guttation (hydathodes) vs. Transpiration (stomata).
- **Time**: Guttation (night/early morning) vs. Transpiration (daytime).
- **Water Composition**: Guttation (impure water) vs. Transpiration (pure water).

### Final Answer:
Guttation differs from transpiration in that it involves the loss of liquid water through hydathodes, occurs primarily at night, and the water lost can contain impurities, whereas transpiration involves the loss of water vapor through stomata during the day and typically involves pure water.
