Differentiate between guttation and transpiration.

Explanation

**Step-by-Step Solution:**

1. **Definition of Transpiration**:
- Transpiration is the process by which water vapor is lost from the aerial parts of the plant, primarily through small openings called stomata. This process mainly occurs during the daytime when the temperature is high, and the plant is actively photosynthesizing.

2. **Mechanism of Transpiration**:
- Water is absorbed by the roots from the soil and moves upward through the plant to the leaves. In the leaves, water evaporates into the atmosphere in the form of vapor through the stomata. This loss of water vapor creates a negative pressure (transpirational pull) that helps in the upward movement of water and nutrients from the roots.
