The correct Answer is:
**Step-by-Step Solution:** 1. **Identify the Organism**: The question refers to Spirogyra, which is a filamentous green algae known for its spiral chloroplasts. 2. **Understand the Structure**: Spirogyra consists of unbranched cylindrical cells that form filaments. These cells are essential for the growth and length of the filament. 3. **Cell Division Process**: The length of Spirogyra filaments increases primarily through cell division. The type of division that occurs in these cells is called transverse division. 4. **Identify the Cells Involved**: The cells that undergo division to increase the length of the filament are referred to as "every green cell." These green cells are the unbranched cylindrical cells that make up the filament. 5. **Conclusion**: Therefore, the correct answer to the question is that Spirogyra filaments increase in length due to division in every green cell. **Final Answer**: Every green cell. ---
