Select the incorrect statement w.r.t. plant body of bryophytes.

Options

A. It is thallus like and may be prostrate or erect
B. It lack true roots, stems or leaves
C. Xylem and phloem are present
D. It is attached to substratum by unicellular or multicellular rhizoids

Answer

To solve the question of selecting the incorrect statement regarding the plant body of bryophytes, we can analyze each statement provided in the options.

### Step-by-Step Solution:

1. **Understanding Bryophytes**:
- Bryophytes are non-vascular plants that include mosses, liverworts, and hornworts. They typically have a simple structure and lack true vascular tissues.

2. **Analyzing the First Statement**:
- **Statement**: "It is thallus-like and may be prostate or erect."
- **Evaluation**: This statement is correct. Bryophytes can have a thallus structure, which can either lie flat on the ground (prostrate) or grow upright (erect).

3. **Analyzing the Second Statement**:
- **Statement**: "It lacks true roots, stem, or leaves."
- **Evaluation**: This statement is also correct. Bryophytes do not have true roots, stems, or leaves as found in higher plants. Instead, they have structures that perform similar functions but are not classified as true roots, stems, or leaves.

4. **Analyzing the Third Statement**:
- **Statement**: "Xylem and phloem are present."
- **Evaluation**: This statement is incorrect. Bryophytes do not have xylem and phloem, which are the vascular tissues responsible for the transport of water and nutrients in vascular plants. Instead, they rely on diffusion for the movement of water and nutrients.

5. **Analyzing the Fourth Statement**:
- **Statement**: "It is attached to substratum by unicellular and multicellular rhizoids."
- **Evaluation**: This statement is correct. Bryophytes are anchored to their substrate by rhizoids, which can be unicellular or multicellular.

6. **Conclusion**:
- The incorrect statement regarding the plant body of bryophytes is the third statement: "Xylem and phloem are present."

### Final Answer:
The incorrect statement with respect to the plant body of bryophytes is: **"Xylem and phloem are present."**
