Water absorbed by root in order to meet the requirement of transpiration is due to

Options

A. Transpiration pull
B. Osmosis
C. Imbibition
D. Plasmolysis

Answer

To answer the question "Water absorbed by root in order to meet the requirement of transpiration is due to," we need to analyze the options provided and understand the processes involved in water absorption by roots.

### Step-by-Step Solution:

1. **Understanding Transpiration**:
- Transpiration is the process where water is lost from the aerial parts of the plant, primarily through small openings called stomata on leaves. This loss of water creates a negative pressure within the plant.

**Hint**: Remember that transpiration is about water loss, not absorption.

2. **Identifying the Role of Transpiration Pull**:
- The negative pressure created by transpiration results in a "transpiration pull," which helps in drawing water upward from the roots through the xylem vessels. However, this pull does not directly cause water absorption at the roots.

**Hint**: Transpiration pull helps move water but does not explain how water enters the roots.

3. **Understanding Osmosis**:
- Osmosis is the movement of water across a semi-permeable membrane from an area of higher water concentration (or lower solute concentration) to an area of lower water concentration (or higher solute concentration). In the case of roots, water moves from the soil (high water concentration) into the root cells (low water concentration).

**Hint**: Focus on how water moves into the roots; think about concentration gradients.

4. **Analyzing Other Options**:
- **Emission**: This term does not relate to the absorption of water by roots.
- **Plasmolysis**: This is the process where cells lose water and shrink, which is the opposite of absorption.
- **Imbibition**: This refers to the absorption of water by solids, not specifically by roots.

**Hint**: Eliminate options that do not pertain to the absorption process.

5. **Conclusion**:
- Based on the understanding of osmosis and the role of transpiration, the correct answer to the question is **osmosis**. This process is responsible for the absorption of water by the roots to meet the plant's transpiration needs.

### Final Answer:
Water absorbed by root in order to meet the requirement of transpiration is due to **osmosis**.
