The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Swarm Spores**: First, we need to identify what swarm spores are. Swarm spores are also known as flagella or zoospores. They are characterized by having flagella, which are tail-like structures that enable movement. 2. **Characteristics of Swarm Spores**: These spores are motile, meaning they can move from one location to another. This motility is crucial for their role in reproduction. 3. **Examining Different Organisms**: - **Penicillium**: This organism reproduces asexually and produces non-motile spores called conidia. Therefore, it cannot be the answer. - **Rhizopus**: Known as bread mold, Rhizopus also reproduces asexually and produces sporangia, which are haploid spores. This means it does not produce swarm spores. - **Aspergillus**: Similar to the previous two, Aspergillus reproduces asexually and produces conidia, which are also non-motile spores. Thus, it is not the correct answer. - **Chlamydomonas**: This organism can reproduce both asexually and sexually. In its sexual reproduction, it produces zoospores, which are motile and have flagella. This aligns with the definition of swarm spores. 4. **Conclusion**: Based on the analysis of the different organisms, the correct answer to the question "Swarm spores are produced by" is **Chlamydomonas**. ---
