Bryophytes are close to pteridophytes in having

Options

A. multicellualr jacketed sex organs
B. flagellated oosphere
C. mitospores in life cycle
D. all of the above

Answer

To solve the question "Bryophytes are close to pteridophytes in having," we need to analyze the options provided and determine which characteristic is shared between bryophytes and pteridophytes.

### Step-by-Step Solution:

1. **Understanding Bryophytes and Pteridophytes**:
- Bryophytes are non-vascular plants that include mosses, liverworts, and hornworts. They reproduce via spores and have structures called gametangia for sexual reproduction.
- Pteridophytes are vascular plants that include ferns and their relatives. They also reproduce via spores but have more complex structures.

2. **Analyzing the Options**:
- **Option A: Multicellular jacketed sex organs**:
- Bryophytes possess multicellular sex organs known as archegonia (female) and antheridia (male), which are surrounded by a layer of sterile cells providing protection.
- Pteridophytes also have multicellular jacketed sex organs.
- This option is likely to be correct.

- **Option B: Flagellated oospere**:
- The oosphere is the female gamete in bryophytes, which is indeed flagellated in some species. However, this characteristic is not shared with pteridophytes, as their gametes are not flagellated.
- This option is incorrect.

- **Option C: Mitospores in life cycle**:
- Mitospores are characteristic of algae and are not found in either bryophytes or pteridophytes.
- This option is incorrect.

- **Option D: All of the above**:
- Since options B and C are incorrect, this option cannot be correct.

3. **Conclusion**:
- The only correct option that indicates a shared characteristic between bryophytes and pteridophytes is **Option A: Multicellular jacketed sex organs**.

### Final Answer:
Bryophytes are close to pteridophytes in having **multicellular jacketed sex organs**.
