Guttation is the result of

Options

A. Diffusion
B. transpiration
C. Osmosis
D. Root pressure

Answer

**Step-by-Step Solution:**

1. **Understand Guttation**: Guttation is defined as the process by which plants excrete excess water from their leaf tips. This typically occurs when the soil is moist, and the plant roots absorb more water than the plant can use.

2. **Differentiate Guttation from Transpiration**: It is important to note that guttation is different from transpiration. Transpiration involves the loss of water vapor from the stomata of leaves and is influenced by factors such as sunlight and humidity, while guttation does not depend on these factors.

3. **Role of Root Pressure**: Guttation occurs as a result of root pressure. When the soil is saturated with water, the roots continue to absorb water, leading to an increase in pressure within the roots. This pressure forces water upward through the plant and eventually causes excess water to be expelled from the leaf tips.

4. **Conclusion**: Based on the explanation, the correct answer to the question "Guttation is the result of" is **Root Pressure**.
