Choose odd one w.r.t. spore produced in the life cycle of Penicilium

Options

A. Meiospore as ascospore
B. Exogenously produced conidia
C. Endogenous sexual spore
D. Black coloured telutospores

Answer

To determine the odd one out with respect to the spores produced in the life cycle of Penicillium, we need to analyze the options provided and their relevance to Penicillium's reproductive structures.

### Step-by-Step Solution:

1. **Identify the Types of Spores**:
- The question asks us to consider the different types of spores produced in the life cycle of Penicillium. The options include:
- Meiospores
- Exogenously produced conidia
- Endogenous sexual spores
- Black colored telutospores

2. **Analyze Meiospores**:
- Meiospores are produced through meiosis, which is a form of sexual reproduction. In fungi, these spores are involved in the formation of gametes. In the context of Penicillium, meiospores can be considered a part of its reproductive cycle.

3. **Analyze Exogenously Produced Conidia**:
- Conidia are asexual spores produced externally (exogenously) on specialized structures. In Penicillium, conidia are the primary means of asexual reproduction, making this option relevant to the life cycle of Penicillium.

4. **Analyze Endogenous Sexual Spores**:
- Endogenous sexual spores are produced internally (endogenously) and involve the transfer of genetic material through structures called gametangia. This is also relevant to the reproductive cycle of Penicillium.

5. **Analyze Black Colored Telutospores**:
- Telutospores are a type of spore found in certain fungi, particularly in the Basidiomycetes. They are characterized by their thick walls and specific structures, which are not present in Penicillium. This makes telutospores distinct from the other types of spores mentioned.

6. **Conclusion**:
- Based on the analysis, the odd one out with respect to the spores produced in the life cycle of Penicillium is the **black colored telutospores**. This is because they are not produced by Penicillium, while the other three types of spores are associated with its life cycle.

### Final Answer:
The odd one out is **black colored telutospores**.
