Bryophytes differ from thallophytes in having :-

Options

A. Embryo
B. Rhizoids
C. Sterile jacket around sex organs
D. All the above

Answer

To answer the question "Bryophytes differ from thallophytes in having:", we need to analyze the characteristics of both groups of plants.

### Step-by-Step Solution:

1. **Identify the Groups**:
- Bryophytes include mosses and liverworts.
- Thallophytes include algae.

2. **Understand Basic Structures**:
- Thallophytes (algae) have a simple thalloid body and lack true roots, stems, or leaves.
- Bryophytes, on the other hand, have more complex structures.

3. **Examine Reproductive Structures**:
- Bryophytes possess specialized reproductive organs: male (antheridium) and female (archegonium).
- Thallophytes do not have such specialized structures.

4. **Sterile Jacket Presence**:
- In bryophytes, both the antheridium and archegonium are surrounded by a sterile jacket layer. This layer provides protection to the reproductive cells.
- Thallophytes do not have this feature.

5. **Conclusion**:
- The key difference is that bryophytes have a sterile jacket around their sex organs, which is not present in thallophytes.

### Final Answer:
Bryophytes differ from thallophytes in having a sterile jacket around their reproductive organs.
