Answer

**Step-by-Step Solution:**

1. **Understanding Conjugation in Spirogyra**:
- Spirogyra is a filamentous green alga that reproduces sexually through a process called conjugation.

2. **Definition of Conjugation**:
- Conjugation involves the fusion of adjacent cells from the same filament. This process leads to the formation of gametes.

3. **Formation of Gametes**:
- During conjugation, one cell acts as the male gamete and the other as the female gamete. The male gamete migrates to the female gamete.

4. **Protoplast Formation**:
- As the male gamete migrates, both gametes develop protoplasts (the living part of the cell).

5. **Fusion of Gametes**:
- The fusion of the male and female protoplasts occurs, resulting in the formation of a zygote.

6. **Product of Conjugation**:
- The final product of this conjugation process is called a zygospore.

7. **Conclusion**:
- Therefore, the product of conjugation in Spirogyra is known as zygospores.

**Final Answer**: The product of conjugation of Spirogyra is called zygospores.
