Select an incorrect staments.

Options

A. Diffusion in the movement of molecules by random thermal agitation.
B. Diffusion in the movement of molecules by random thermal agitation.
C. Channels are transmembrane proteins that function as selective pores
D. Aquaporins form hydrophobic transmembrane channels for the passage of water.

Explanation

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

### Step-by-Step Solution:

1. **Analyze the First Statement:**
- The statement mentions that diffusion is the movement of molecules by random thermal agitation and is a type of passive transport.
- **Evaluation:** This statement is correct. Diffusion does occur without the need for ATP and moves molecules from a region of higher concentration to a region of lower concentration.

2. **Analyze the Second Statement:**
- The second statement also discusses diffusion and mentions the movement of molecules by random thermal fission.
- **Evaluation:** This statement is also correct. Like the first statement, it describes diffusion accurately, emphasizing its role in gaseous movement in plants.

3. **Analyze the Third Statement:**
- The third statement states that channels are transmembrane proteins that function as selective pores.
- **Evaluation:** This statement is correct. Channels indeed serve as selective pores in the membrane, facilitating the transport of specific molecules.

4. **Analyze the Fourth Statement:**
- The fourth statement discusses aquaporins, stating that they form hydrophobic transmembrane channels for the passage of water.
- **Evaluation:** This statement is incorrect. Aquaporins actually form hydrophilic transmembrane channels that allow water to pass through, not hydrophobic channels.

### Conclusion:
The incorrect statement is the fourth one regarding aquaporins.

### Final Answer:
The incorrect statement is: "Aquaporins form hydrophobic transmembrane channels for the passage of water."
