The common mode of reproduction in Rhizopus is by

Options

A. Sporangiospores
B. Oidia
C. Plasmospores
D. Zoospores.

Answer

### Step-by-Step Solution:

1. **Understanding Rhizopus**:
- Rhizopus is a genus of fungi that typically grows as filamentous structures. These structures are known as hyphae, which are branching and lack cross walls (septae).

2. **Reproductive Methods**:
- Rhizopus can reproduce both asexually and sexually. It is important to identify the common mode of reproduction.

3. **Asexual Reproduction**:
- In asexual reproduction, Rhizopus primarily forms asexual spores. The specific type of asexual spores produced by Rhizopus is called sporangiospores.

4. **Formation of Sporangiospores**:
- Sporangiospores are produced inside a specialized structure known as a sporangium. The sporangium is bulbous and spherical in shape.

5. **Conclusion**:
- Therefore, the common mode of reproduction in Rhizopus is by sporangiospores, which are produced in the sporangium.

### Final Answer:
The common mode of reproduction in Rhizopus is by **sporangiospores**.
