Neurospora forms :

Options

A. Endogenous asexual and exogenous sexual spore
B. Conidia as asexual and basidiospore as sexual spore
C. Exogenous asexual and endogenous sexual spore
D. Zoospore as asexual and ascospore as sexual spore

Answer

**Step-by-Step Solution:**

1. **Understanding Neurospora**: Neurospora is a genus of fungi that is commonly used in genetic studies. It reproduces both asexually and sexually.

2. **Identifying Spores**:
- Asexual spores are produced without the fusion of gametes. In Neurospora, the main type of asexual spores produced are called **conidia**.
- Sexual spores are produced through the fusion of gametes. In Neurospora, the sexual spores are known as **ascospores**.

3. **Evaluating the Options**:
- **Option 1**: Endogenous asexual and exogenous sexual spores. This is incorrect because Neurospora produces exogenous asexual spores (conidia) and endogenous sexual spores (asci containing ascospores).
- **Option 2**: Conidia are asexual and vesidospore as sexual spores. This is incorrect because while conidia are indeed asexual spores, the term "vesidospore" is not applicable; the correct term is ascospores for sexual reproduction.
- **Option 3**: Exogenous asexual and endogenous sexual spores. This is incorrect because Neurospora produces exogenous asexual spores (conidia) and endogenous sexual spores (asci containing ascospores).
- **Option 4**: Zoospores as asexual and escospore as sexual spore. This is incorrect because Neurospora does not produce zoospores; it produces conidia as asexual spores and ascospores as sexual spores.

4. **Conclusion**: The correct classification for Neurospora is that it forms **conidia** as asexual spores and **ascospores** as sexual spores.

**Final Answer**: Neurospora forms conidia (asexual spores) and ascospores (sexual spores).
