The branches of conidiophores of Penicillium end in conidia bearing bottle shapad structures which are called.

Options

A. Metulae
B. Sterigmata
C. Paraphyses
D. Ramenta.

Answer

To solve the question regarding the branches of conidiophores of Penicillium and the bottle-shaped structures they bear, 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 (asexual spores).
- In Penicillium, these structures are often branched.

**Hint**: Remember that conidiophores are essential for asexual reproduction in fungi.

2. **Identifying the Branches**:
- The branches of conidiophores in Penicillium are referred to as "metulae."
- However, the question specifically asks about the structures that bear the conidia.

**Hint**: Focus on the specific function of the branches in relation to conidia.

3. **Recognizing the Bottle-Shaped Structures**:
- The terminal ends of the branches (metulae) produce conidia through structures that are bottle-shaped.
- These bottle-shaped structures are known as "sterigmata."

**Hint**: Think about the shape and function of the structures that directly produce the spores.

4. **Evaluating the Options**:
- The options given are: Metulae, Sterigmata, Paraphysis, and Ruminata.
- Since we have identified that the bottle-shaped structures are called sterigmata, we can conclude that this is the correct answer.

**Hint**: Eliminate the options one by one based on their definitions and functions in fungi.

5. **Final Answer**:
- The branches of conidiophores of Penicillium end in conidia-bearing bottle-shaped structures called **sterigmata**.

### Summary:
The correct answer to the question is **sterigmata**, which are the bottle-shaped structures at the ends of the branches of conidiophores in Penicillium that bear conidia.
