Spirogyra differs from Mucor in having

Options

A. Zygosporangia
B. Uninuclear gametangia
C. Anisogametes
D. Multicellular gametes.

Answer

**Step-by-Step Solution:**

1. **Identify the Organisms**: Understand that Spirogyra and Mucor are two different types of organisms. Spirogyra is a green alga, while Mucor is a fungus.

2. **Understand Their Classification**:
- Spirogyra belongs to the kingdom Plantae (specifically the division Chlorophyta).
- Mucor belongs to the kingdom Fungi (specifically the class Zygomycetes).

3. **Reproductive Structures**:
- In Spirogyra, the reproductive structures are known as gametangia, which are uninuclear (containing one nucleus).
- In Mucor, the reproductive structures are also called gametangia, but they are multinucleate (containing multiple nuclei).

4. **Sexual Reproduction**:
- Spirogyra reproduces sexually through the fusion of gametes produced in its uninuclear gametangia.
- Mucor reproduces sexually through the fusion of its multinucleate gametangia, leading to the formation of zygospores.

5. **Conclusion**: The key difference between Spirogyra and Mucor in terms of their reproductive structures is that Spirogyra has uninuclear gametangia, while Mucor has multinucleate gametangia.

6. **Final Answer**: Therefore, Spirogyra differs from Mucor in having **uninuclear gametangia**.
