Select the incorrect statement from the following ?

Options

A. Phloem translocates the food material in bidirectional manner.
B. Short distance transport in plants occurs by diffusion and cytoplasmic streaming
C. Transport through xylem occurs in bidirectional manner
D. Xylem transports the water, minerals and some organic nitrogen

Answer

To solve the question of selecting the incorrect statement from the given options, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Analyze the First Statement**:
- The first statement claims that "the phloem translocates food in a bidirectional manner."
- This statement is true. Phloem is responsible for transporting food (sugars) produced in the leaves to various parts of the plant, including storage organs, and it can transport in both directions depending on the plant's needs.

2. **Analyze the Second Statement**:
- The second statement states that "short distance transport in plants occurs by diffusion in cytoplasmic stream."
- This statement is also true. Diffusion is indeed a passive transport mechanism that allows substances to move over short distances within the plant cells.

3. **Analyze the Third Statement**:
- The third statement says, "transport to xylem occurs in a bidirectional manner."
- This statement is incorrect. Xylem primarily transports water and minerals from the roots upwards to the stems and leaves. It does not transport in a bidirectional manner; the movement is unidirectional (from roots to leaves).

4. **Conclusion**:
- After analyzing all three statements, the incorrect statement is the third one: "transport to xylem occurs in a bidirectional manner."

### Final Answer:
The incorrect statement is: **"Transport to xylem occurs in a bidirectional manner."**
