Select an incorrect statement for bryophytes

Options

A. Plant body of bryophytes is more differentiated than that of algae.
B. They may possess root-like, leaf-like or stem-like structures
C. Sex organs in bryophytes are multicellular
D. Female sex organ called archegonium is flask-shaped and produces multiple eggs

Answer

To solve the question "Select an incorrect statement for bryophytes," we will analyze each of the provided statements regarding bryophytes and determine which one is incorrect.

### Step-by-Step Solution:

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

2. **Evaluating the Statements**:
- **Statement 1**: "The plant body of bryophytes is more differentiated than that of algae."
- This statement is **true**. Bryophytes have a more complex structure than algae, even though they are still relatively simple compared to higher plants.

- **Statement 2**: "They may possess root-like, leaf-like or stem-like structures."
- This statement is also **true**. Bryophytes have structures that resemble roots (rhizoids), leaves, and stems, although they are not true roots, leaves, or stems.

- **Statement 3**: "Sex organs in bryophytes are multicellular."
- This statement is **true**. The sex organs in bryophytes, such as antheridia (male) and archegonia (female), are indeed multicellular.

- **Statement 4**: "The female sex organ called archegonium is flask-shaped and produces multiple eggs."
- This statement is **incorrect**. The archegonium is flask-shaped and produces **only one egg** (oosphere), not multiple eggs.

3. **Conclusion**:
- The incorrect statement regarding bryophytes is the fourth one: "The female sex organ called archegonium is flask-shaped and produces multiple eggs."

### Final Answer:
The incorrect statement for bryophytes is: "The female sex organ called archegonium is flask-shaped and produces multiple eggs."
