The correct Answer is:
**Step-by-Step Solution:** 1. **Identify the Organism:** - Spirogyra is a type of green algae that belongs to the division Chlorophyta. 2. **Understand the Structure:** - Spirogyra has chloroplasts that are arranged in a spiral or ribbon-like shape. This allows it to perform photosynthesis. 3. **Modes of Reproduction:** - Spirogyra can reproduce in two ways: asexually and sexually. 4. **Asexual Reproduction:** - The asexual mode of reproduction in Spirogyra occurs through fragmentation. In this process, the organism breaks into smaller pieces, and each piece can grow into a new individual. 5. **Sexual Reproduction:** - The sexual mode of reproduction occurs through a process called conjugation. In conjugation, two filaments of Spirogyra align and fuse, leading to the formation of a zygote. 6. **Determine the Most Common Mode:** - While Spirogyra can reproduce both asexually (by fragmentation) and sexually (by conjugation), fragmentation is the most common mode of reproduction. 7. **Conclusion:** - Therefore, the most common mode of reproduction in Spirogyra is fragmentation. **Final Answer:** The most common mode of reproduction in Spirogyra is **fragmentation**. ---
