The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks about the sex organs called antheridia and archegonia. We need to identify which organism possesses these structures. 2. **Identifying the Options**: The options provided are: - Spirogyra - Mucor - Moss - Pyxinia 3. **Analyzing Each Option**: - **Spirogyra**: This organism reproduces sexually through the fusion of isogametes, which are morphologically similar. It does not have specialized sex organs like antheridia and archegonia. - **Mucor**: In Mucor, sexual reproduction occurs via gametangial conjugation, where two hyphae of opposite strains come together. Again, it does not have antheridia or archegonia. - **Moss**: Mosses are bryophytes that possess both antheridia (the male sex organ) and archegonia (the female sex organ). These structures are responsible for producing male and female gametes respectively. - **Pyxinia**: This organism does not have antheridia and archegonia as its sex organs; instead, it has spermatia and hyphae. 4. **Conclusion**: Based on the analysis, the correct answer is **Moss**, as it is the only organism listed that has both antheridia and archegonia as its sex organs. 5. **Final Answer**: Antheridia and archegonia are sex organs of **Moss**. ---
