Select an incorrect statement

Options

A. The uptake of water through xylem vessels is possible in large-sized plants through capillarity.
B. Capillarity refers to a rise in water due to the forces of adhesion and cohesion.
C. Adhesive forces attract molecules of different kinds
D. Cohesive forces attract molecules of the same kind to each other.

Answer

To solve the question of selecting an incorrect statement regarding transport in plants, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Statement Analysis**:
- **Statement 1**: "The uptake of water through xylem vessels is possible in large-sized plants through capillarity."
- **Analysis**: This statement is incorrect. While capillarity plays a role in water movement, it is not sufficient for the uptake of water in large plants. The primary mechanisms for water transport in tall plants are root pressure and the cohesion-tension theory (transpiration pull), not just capillarity.

2. **Statement 2**: "Capillarity refers to rise in water due to force of adhesion and cohesion."
- **Analysis**: This statement is correct. Capillarity is indeed the result of both adhesion (water molecules sticking to the walls of the xylem) and cohesion (water molecules sticking to each other), which allows water to rise in narrow tubes.

3. **Statement 3**: "Adhesive forces attract molecules of different types."
- **Analysis**: This statement is also correct. Adhesion refers to the attraction between water molecules and different surfaces, such as the walls of xylem vessels.

4. **Statement 4**: "Cohesion means the attraction between the same kind of molecules."
- **Analysis**: This statement is correct. Cohesion is the attraction between similar molecules, such as water molecules attracting each other.

5. **Conclusion**:
- After analyzing all statements, we find that the first statement is incorrect. The other three statements are correct.

### Final Answer:
The incorrect statement is **Statement 1**: "The uptake of water through xylem vessels is possible in large-sized plants through capillarity."
