Which type of water is used by the plants ?

Options

A. Gravitational water
B. Capillary water
C. hygroscopic water
D. chemically bound water

Answer

To answer the question "Which type of water is used by the plants?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Types of Water in Soil**:
- There are different types of water that can be found in soil: gravitational water, capillary water, hygroscopic water, and chemically bound water.

2. **Identify the Role of Root Hairs**:
- Plants absorb water primarily through their roots, specifically through structures called root hairs. These root hairs are tiny extensions that increase the surface area for absorption.

3. **Determine the Type of Water Absorbed**:
- Among the types of water mentioned, only a small fraction of the total water in the soil can be absorbed by plants. This fraction is known as capillary water.

4. **Characteristics of Capillary Water**:
- Capillary water is found in thin layers around soil particles and fills the spaces between them. It is the water that is available for plants to absorb.

5. **Conclusion**:
- Based on the information gathered, the type of water that plants primarily use is **capillary water**.

### Final Answer:
Plants primarily use **capillary water** for their absorption needs.
