In which of the following asexual reproduction, a maternal cell produ8ces innumerable unicellular unincleate offspring

Options

A. Sporulation
B. Fragmentation
C. Pathenogenesis
D. Multiple fission

Answer

To solve the question regarding which type of asexual reproduction involves a maternal cell producing innumerable unicellular uninucleate offspring, we can analyze the provided options step by step.

### Step-by-Step Solution:

1. **Understand the Options**:
- **Sporulation**: This process involves the formation of spores. Spores are produced by the parent organism and can develop into new individuals when conditions are favorable. However, they are not unicellular uninucleate offspring directly produced from a maternal cell.

- **Fragmentation**: In fragmentation, the parent organism breaks into pieces (fragments), and each fragment can grow into a new individual. This method does not specifically produce unicellular uninucleate offspring, as the fragments can be multicellular.

- **Parthenogenesis**: This is a form of asexual reproduction where an egg develops into an embryo without fertilization. While it can produce offspring, it typically involves the development of a single egg into a multicellular organism, not numerous unicellular uninucleate offspring.

- **Multiple Fission**: In this process, a single maternal cell undergoes multiple divisions to produce many offspring simultaneously. The nucleus of the parent cell divides several times (often by amitosis), resulting in several nuclei, and then the cytoplasm divides, creating multiple unicellular uninucleate offspring.

2. **Identify the Correct Answer**:
- After analyzing all options, **Multiple Fission** is the only process that fits the description of a maternal cell producing innumerable unicellular uninucleate offspring.

3. **Conclusion**:
- Therefore, the correct answer to the question is **Option D: Multiple Fission**.
