Guttation takes place through

Options

A. cuticle
B. stomata
C. lenticels
D. hydathodes

Answer

**Step-by-Step Solution:**

1. **Understanding Guttation**: Guttation is the process where water droplets are expelled from the leaves of plants, typically occurring at night or early in the morning. This phenomenon is often observed as small droplets on the leaf tips or edges.

2. **Identifying the Structures Involved**: The water that is expelled during guttation comes from specialized structures in the plant known as hydathodes. Hydathodes are specialized pores located on the leaf margins or tips.

3. **Function of Hydathodes**: Hydathodes allow for the release of excess water from the plant, particularly when the soil moisture is high, and transpiration is low. This process is different from transpiration, which occurs through stomata during the daytime.

4. **Evaluating the Options**:
- **Cuticle**: This is a waxy layer on the surface of leaves that helps reduce water loss. It does not facilitate guttation.
- **Stomata**: These are openings that allow for gas exchange and transpiration, but they are not involved in guttation.
- **Lenticels**: These are small openings in the stems of plants that allow for gas exchange, similar to stomata, but they do not play a role in guttation.
- **Hydathodes**: These are the correct structures through which guttation occurs.

5. **Conclusion**: Guttation takes place through hydathodes, which are specialized structures in the leaves that allow for the expulsion of excess water.

**Final Answer**: Guttation takes place through hydathodes.
