Which of the following spores are produced endogenously?

Options

A. Zoospores and Conidia
B. Conidia and aplanospores
C. Aplanospores and zoospores
D. Aplanospore, zoospores and conidia

Answer

To determine which spores are produced endogenously, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Types of Spores**:
- Spores can be classified based on their mode of production into two main types: endogenous and exogenous.
- Endogenous spores are produced within a structure, while exogenous spores are produced outside of a structure.

2. **Identify Endogenous Spores**:
- Endogenous spores include:
- **Zoospores**: These are motile spores that are produced within a sporangium. They are typically flagellated and can move in water.
- **Aplanospores**: These are non-motile spores that are also produced within a sporangium.

3. **Identify Exogenous Spores**:
- Exogenous spores include:
- **Conidia**: These are asexual spores that are produced externally on specialized structures.

4. **Conclusion**:
- Based on the definitions and classifications, the spores that are produced endogenously are **zoospores** and **aplanospores**.

### Final Answer:
The spores that are produced endogenously are **zoospores** and **aplanospores**.
