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 an incorrect statement regarding transport in plants, we will analyze each statement provided.

### Step-by-Step Solution:

1. **Understanding Diffusion**:
- The first statement claims that "diffusion is the movement of molecules by random thermal agitation."
- **Analysis**: This statement is correct. Diffusion involves the movement of molecules from a region of higher concentration to a region of lower concentration due to random thermal motion.

2. **Reiterating Diffusion**:
- The second statement is similar to the first, stating the same definition of diffusion.
- **Analysis**: This statement is also correct for the same reasons as the first.

3. **Transmembrane Proteins and Channels**:
- The third statement mentions that "channels are transmembrane proteins that function as selective modes."
- **Analysis**: This statement is correct. Transmembrane proteins, including channels, facilitate the selective transport of substances across the membrane.

4. **Aquaporins and Their Function**:
- The fourth statement states that "aquaporins form hydrophobic transmembrane channels for the passage of water."
- **Analysis**: This statement is incorrect. Aquaporins are indeed transmembrane proteins that facilitate the passage of water, but they form hydrophilic channels, not hydrophobic ones.

### Conclusion:
- The incorrect statement is the fourth one, which mischaracterizes the nature of aquaporins.

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