Select the matched ones (i) Guttation-Water loss in liquid phase (ii) Adhesion- Mutual attraction between water molecules (iii) Imbibition-Absorption of water by dry wood (iv) Hypotonic solution-Cells shrink

Options

A. I,ii and and iii only
B. ii and iv only
C. iii and iv only
D. I and iii only

Answer

To solve the question, we need to evaluate each statement and determine if they are correctly matched. Let's analyze each option step by step.

### Step-by-Step Solution:

1. **Guttation - Water loss in liquid phase**
- Guttation refers to the exudation of water droplets from the edges of leaves, especially during the night or early morning. This process involves the loss of water in liquid form, making this statement correct.
- **Conclusion**: This statement is **correct**.

2. **Adhesion - Mutual attraction between water molecules**
- Adhesion is the attraction between different types of molecules, such as water molecules and the molecules of the xylem vessels. The mutual attraction between water molecules themselves is referred to as cohesion, not adhesion. Therefore, this statement is incorrect.
- **Conclusion**: This statement is **incorrect**.

3. **Imbibition - Absorption of water by dry wood**
- Imbibition is the process where a dry substance, such as wood, absorbs water and swells. This is a correct definition of imbibition.
- **Conclusion**: This statement is **correct**.

4. **Hypotonic solution - Cells shrink**
- In a hypotonic solution, the concentration of solutes outside the cell is lower than inside the cell. Water moves into the cell, causing it to swell, not shrink. Therefore, this statement is incorrect.
- **Conclusion**: This statement is **incorrect**.

### Final Evaluation:
- The matched statements are:
- (i) Guttation - Water loss in liquid phase (Correct)
- (ii) Adhesion - Mutual attraction between water molecules (Incorrect)
- (iii) Imbibition - Absorption of water by dry wood (Correct)
- (iv) Hypotonic solution - Cells shrink (Incorrect)

Thus, the correct matched statements are (i) and (iii).

### Answer:
The matched ones are (i) Guttation - Water loss in liquid phase and (iii) Imbibition - Absorption of water by dry wood.
