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 act of exuding or releasing substances. In the context of plants, it generally refers to the release of fluids, but it does not specifically describe the process of water loss in droplets. Therefore, this option is incorrect.

2. **Guttation**: This is the process we are looking for. Guttation is the exudation of water in the form of liquid droplets from the specialized openings called hydathodes, which are found at the tips of vascular plants like grass. This process occurs when the soil moisture is high, and the plant roots absorb more water than the plant can transpire. Thus, the excess water is expelled as droplets. Hence, this option is correct.

3. **Transpiration**: This is the process of water loss from plants, but it occurs in the form of water vapor through small openings called stomata. Since the question specifically asks about liquid droplets, this option is incorrect.

4. **Imbibation**: This refers to the absorption of water by a substance, typically resulting in swelling. It does not involve the loss of water, so this option is also incorrect.

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

### Step-by-Step Solution:
1. **Identify the process**: Understand that the question is asking about a specific process related to water loss in plants.
2. **Evaluate the options**: Go through each option provided and analyze their definitions and relevance to the question.
3. **Determine the correct term**: Recognize that guttation specifically refers to the loss of water in liquid droplet form from special openings in the plant.
4. **Conclude with the answer**: Confirm that the correct answer is guttation.
