Bryophytes can be distinguished from algae/fungi/thallophytes because they have

Options

A. thallus,haploid ,gametophytic body
B. chloroplast
C. no conducting tissue
D. sterile jacket of cells around multicellular sex organs.

Answer

To distinguish bryophytes from algae, fungi, and thallophytes, we can analyze the characteristics of these groups step by step:

### Step-by-Step Solution:

1. **Understanding Bryophytes**:
- Bryophytes are non-vascular plants that include mosses, liverworts, and hornworts. They have a dominant gametophyte stage in their life cycle.

2. **Comparing with Algae and Fungi**:
- Algae and fungi are part of thallophytes. Thallophytes are characterized by a thallus-like body, which means they do not have differentiated structures like roots, stems, or leaves.

3. **Thallus Structure**:
- Both bryophytes and thallophytes have a thallus-like body. However, bryophytes have structures that resemble roots (rhizoids), stems, and leaves, even though they are not true roots, stems, or leaves.

4. **Gametophytic Body**:
- Both bryophytes and thallophytes have a haploid gametophytic body. Therefore, this characteristic does not distinguish bryophytes from thallophytes.

5. **Presence of Chloroplasts**:
- Both bryophytes and thallophytes contain chloroplasts, which are essential for photosynthesis. This characteristic is not unique to bryophytes.

6. **Conducting Tissue**:
- Bryophytes do not have true vascular tissues (xylem and phloem), similar to thallophytes. Thus, the absence of conducting tissue does not serve as a distinguishing feature.

7. **Multicellular Sex Organs**:
- A key distinguishing feature of bryophytes is that they have multicellular sex organs (archegonia for female and antheridia for male) that are surrounded by a sterile jacket of cells. This structure is not found in thallophytes.

8. **Conclusion**:
- The correct distinguishing feature of bryophytes from algae, fungi, and thallophytes is the presence of a sterile jacket of cells around their multicellular sex organs.

### Final Answer:
Bryophytes can be distinguished from algae, fungi, and thallophytes because they have a **sterile jacket of cells around multicellular sex organs**.
