Choose the wrong statement with regard to the members of fungi

Options

A. Yeast is unicellular and useful in fermentation
B. Penicillium is multicellular and produces antibiotics
C. Neurospora is used in the study of biochemical genetics
D. Morels and truffles are poisonous mushrooms

Answer

To solve the question "Choose the wrong statement with regard to the members of fungi," we will analyze each statement provided and determine which one is incorrect.

### Step-by-Step Solution:

1. **Identify the Groups of Fungi**:
- The kingdom Fungi is divided into several groups, including:
- Phycomycetes (lower fungi)
- Ascomycetes (sac fungi)
- Basidiomycetes (club fungi)
- Deuteromycetes (fungi imperfecti)

2. **Evaluate the First Statement**:
- "Yeast is unicellular and used in fermentation."
- Yeast, specifically Saccharomyces cerevisiae, is indeed a unicellular fungus used in fermentation processes like brewing and baking.
- **Conclusion**: This statement is **true**.

3. **Evaluate the Second Statement**:
- "Penicillium is multicellular and produces antibiotic."
- Penicillium is a genus of fungi that is multicellular and is known for producing the antibiotic penicillin.
- **Conclusion**: This statement is **true**.

4. **Evaluate the Third Statement**:
- "Neurospora is used for the study of biochemical genetics."
- Neurospora is a model organism in genetics and is often referred to as the "Drosophila of the plant kingdom" because of its use in genetic studies.
- **Conclusion**: This statement is **true**.

5. **Evaluate the Fourth Statement**:
- "Morals and truffles are poisonous mushrooms."
- Morals and truffles are actually edible fungi and belong to the Ascomycetes group. They are not poisonous.
- **Conclusion**: This statement is **false**.

### Final Answer:
The wrong statement with regard to the members of fungi is: **"Morals and truffles are poisonous mushrooms."**
