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 regarding the wrong statement about fungal species, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Evaluate the First Statement:**
- The statement claims that yeast is unicellular and belongs to Ascomycetes.
- **Analysis:** This is true. Yeast is indeed a unicellular fungus and is classified under the Ascomycetes group. Yeast is widely used in fermentation processes.
- **Conclusion:** This statement is correct.

2. **Evaluate the Second Statement:**
- The statement mentions that Penicillium is multicellular and produces antibiotics.
- **Analysis:** This is also true. Penicillium is a multicellular fungus that belongs to the Ascomycetes and is known for producing the antibiotic penicillin.
- **Conclusion:** This statement is correct.

3. **Evaluate the Third Statement:**
- The statement states that Neurospora is used in the study of biochemical genetics.
- **Analysis:** This is correct as well. Neurospora, a genus of fungi in the Ascomycetes, is often used as a model organism in genetic studies, similar to how Drosophila is used in animal genetics.
- **Conclusion:** This statement is correct.

4. **Evaluate the Fourth Statement:**
- The statement claims that Morals and Truffles are poisonous mushrooms.
- **Analysis:** This statement is incorrect. Morals and Truffles are actually edible fungi and are not poisonous. They are considered delicacies in many cuisines.
- **Conclusion:** This statement is wrong.

### Final Answer:
The wrong statement regarding fungal species is: **"Morals and Truffles are poisonous mushrooms."**
