The correct Answer is:
**Step-by-Step Solution:** 1. **Identify the Organism**: The question asks about Ulothrix, which is a genus of filamentous green algae. 2. **Understand the Characteristics of Ulothrix**: Ulothrix is characterized by non-branching filamentous structures and contains chlorophyll, allowing it to perform photosynthesis. It thrives in both fresh and marine waters and can survive in low temperatures. 3. **Reproductive Methods**: Ulothrix primarily reproduces vegetatively, but it also has a sexual reproduction phase. 4. **Type of Gametes Produced**: In sexual reproduction, Ulothrix produces isogametes. Isogametes are gametes that are similar in shape and size, and in the case of Ulothrix, they are motile and bi-flagellated. 5. **Fusion of Gametes**: The isogametes produced by Ulothrix fuse to form a diploid zygote, which will then develop into a new individual. 6. **Elimination of Other Options**: - Heterogametes refer to gametes that are different in size and shape, which does not apply to Ulothrix. - Basidiospores are spores produced by fungi, not by algae. - Anisogametes are gametes that differ in size and shape, which is also not the case for Ulothrix. 7. **Conclusion**: Therefore, the correct answer is that Ulothrix filaments produce isogametes. ---
