Sexual reproduction takes place through fusion of two gametes. These gametes can be flagellated and similar in size (as in Ulothrix) or non-flagellated (non-motile) but similar in size (as in Spirogyra). Such reproduction is called isogamous

Understanding Sexual Reproduction in Algae
Sexual reproduction is a crucial process in many organisms, including algae. In this context, the question pertains to the type of gametes produced during sexual reproduction.
Non-Flagellated Gametes
- Non-flagellated gametes are gametes that do not possess flagella for motility.
- In many algae, gametes can be either flagellated or non-flagellated, depending on the species.
Similar-Sized Gametes
- Similar-sized gametes refer to isogamous reproduction, where both male and female gametes are morphologically identical.
- This is contrasted with anisogamous reproduction, where the gametes differ in size (e.g., larger female gametes and smaller male gametes).
Identifying the Correct Option: Spirogyra
- Spirogyra is a filamentous green algae that reproduces sexually through a process called conjugation.
- In Spirogyra, both gametes are non-flagellated and of similar size, thereby fulfilling the criteria of the question.
- The conjugation leads to the formation of a zygospore, which can develop into a new organism.
Other Options Explained
- Chlamydomonas: Produces flagellated gametes; not non-flagellated.
- Volvox: Has flagellated sperm and larger non-flagellated eggs.
- Fucus: Exhibits anisogamy with distinct male and female gametes.
Conclusion
Therefore, the correct answer is option 'C' - Spirogyra, as it uniquely demonstrates sexual reproduction using non-flagellated, similar-sized gametes. This distinct reproductive strategy is essential for genetic diversity in the species.
