The yeasts differ from Penicillium in being

Options

A. unicellular
B. multicellular
C. parasitic
D. saprophytic

Answer

To answer the question "The yeasts differ from Penicillium in being," we will analyze the characteristics of both yeasts and Penicillium step by step.

### Step-by-Step Solution:

1. **Identify the Organisms**:
- Yeasts are a type of fungus that are primarily unicellular.
- Penicillium is a genus of fungi that is typically multicellular.

2. **Understand the Structure**:
- Yeasts are composed of single cells, meaning they do not form complex structures.
- Penicillium, on the other hand, consists of a network of filaments called hyphae, which are multicellular.

3. **Review the Options**:
- Option A: Unicellular
- Option B: Multicellular
- Option C: Parasitic
- Option D: Separative

4. **Analyze the Differences**:
- Since yeasts are unicellular, they differ from Penicillium, which is multicellular.
- This means that the main distinction between the two is their cellular structure.

5. **Select the Correct Answer**:
- Based on the analysis, the correct answer is **Option A: Unicellular**. This indicates that yeasts differ from Penicillium in being unicellular.

### Final Answer:
The yeasts differ from Penicillium in being **unicellular** (Option A).
