The conidiophores of Penicillium are

Options

A. uninucleate and colourless
B. uninucleate and pigmented
C. binucleate and pigmented
D. binucleate and colourless

Answer

To answer the question about the conidiophores of Penicillium, we can break down the information step by step.

### Step-by-Step Solution:

1. **Understanding Conidiophores**:
- Conidiophores are specialized structures in fungi that produce conidia, which are asexual spores. In the case of Penicillium, these structures are crucial for reproduction.

2. **Characteristics of Conidiophores**:
- Conidiophores are erect branches of mycelium. This means they stand upright and are part of the fungal body.
- They are responsible for the formation of conidia, which are produced in chains.

3. **Structure of Conidiophores**:
- The conidiophores of Penicillium are typically **uninucleate**, meaning they contain a single nucleus.
- They are also **pigmented**, which gives them color and can be important for their function.

4. **Absence of Food Cells**:
- Conidiophores lack food cells, which means they do not store nutrients in the same way that some other fungal structures might.

5. **Growth Orientation**:
- Conidiophores grow vertically, which is important for the dispersal of conidia into the environment.

6. **Conclusion**:
- Based on the characteristics discussed, the correct description of the conidiophores of Penicillium is that they are **uninucleate and pigmented**.

### Final Answer:
The conidiophores of Penicillium are **uninucleate and pigmented**.
