Loss of water in the form of liquid droplets around special openings of veins near the tip of grass blades is called

Options

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

Answer

To solve the question regarding the loss of water in the form of liquid droplets around special openings of veins near the tip of grass blades, we can analyze the options provided:

1. **Exudation**: This term refers to the process of liquid being released from a plant, but it is not specifically related to the loss of water droplets from the tips of grass blades.

2. **Guttation**: This is the process where water is lost from the plant in the form of liquid droplets, typically through specialized openings called hydathodes, which are often found at the tips of leaves. This is the correct answer to the question.

3. **Transpiration**: This process involves the loss of water vapor from the plant, primarily through stomata. While it is a form of water loss, it does not involve liquid droplets and occurs mainly during the day when the stomata are open.

4. **Imbibition**: This refers to the absorption of water by a substance, such as seeds or dry plant material. It does not relate to the loss of water, so it is not applicable in this context.

Based on this analysis, the correct answer to the question is **Guttation**.

### Step-by-Step Solution:
1. **Identify the Process**: The question asks about the loss of water in the form of liquid droplets.
2. **Evaluate Options**:
- Exudation: Not specific to droplets from grass blades.
- Guttation: Correctly describes the process of liquid water loss from the tips of leaves.
- Transpiration: Involves water vapor loss, not droplets.
- Imbibition: Refers to water absorption, not loss.
3. **Select the Correct Answer**: The correct answer is **Guttation**.
