Swarm spores are produced by

Options

A. Pencillium
B. Rhizopus
C. Aspergillus
D. Chlamydomonas

Answer

**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**.
