Ultimate branches of conidiophore in Penicillium is

Options

A. Rami
B. Phialide
C. Sterigmata
D. Metulae

Answer

To answer the question about the ultimate branches of conidiophore in Penicillium, we will follow these steps:

### Step-by-Step Solution:

1. **Understanding Conidiophores**: Conidiophores are specialized structures in fungi that produce conidia (asexual spores). In Penicillium, these structures are branched.

2. **Identifying the Structure**: The conidiophore in Penicillium has a branched structure, which means it has multiple extensions or branches.

3. **Naming the Branches**: The branches of the conidiophore are referred to by specific names. The main branches are called "rami."

4. **Further Branching**: From the rami, there are smaller branches called "metulae." These are the structures that come off the main branches.

5. **Final Structure**: At the terminal ends of the metulae, there are bottle-shaped structures known as "sterigmata." These sterigmata are responsible for producing the conidia.

6. **Conclusion**: The ultimate branches of the conidiophore in Penicillium are the metulae, as they are the last branching before the formation of sterigmata.

### Final Answer:
The ultimate branches of conidiophore in Penicillium are **Metulae**.
