Which phenomenon is related to the epithem tissue in the tip of grass blades?

Options

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

Answer

To solve the question regarding the phenomenon related to the epithelium tissue in the tip of grass blades, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about a specific phenomenon associated with the epithelium tissue at the tips of grass blades. We need to identify which of the given options (Exudation, Guttation, Transpiration, and Bleeding) is correct.

2. **Defining the Options**:
- **Exudation**: This generally refers to the process of a substance being released from a plant or tissue, but it is not specific to the tips of grass blades.
- **Guttation**: This is the process where drops of xylem sap are exuded from the tips or edges of leaves, particularly in certain vascular plants, including grasses.
- **Transpiration**: This is the loss of water vapor from the aerial parts of plants, primarily through stomata, and is not related to liquid droplets at the tips.
- **Bleeding**: This usually refers to the loss of sap from cut or damaged areas of a plant and is not specific to the tips of leaves.

3. **Identifying the Correct Phenomenon**: Among the options, Guttation is specifically characterized by the exudation of liquid droplets from the tips of leaves, which is associated with the epithelium tissue at the tips of grass blades.

4. **Understanding Guttation**: Guttation occurs due to root pressure, especially during the night or early morning when evaporation rates are low. The excess water in the plant is forced out through specialized structures called hydathodes, which are located at the leaf margins.

5. **Conclusion**: Based on the definitions and characteristics of each option, the correct answer to the question is **Guttation**.

### Final Answer:
The phenomenon related to the epithelium tissue in the tip of grass blades is **Guttation**.
