Yeast and Penicillium/penicillin producing fungus are included under

Options

A. Basidiomycetes
B. Zygomycetes
C. Ascomycetes
D. Phycomycetes

Answer

**Step-by-Step Solution:**

1. **Identify the Organisms**: The question mentions yeast and a fungus that produces penicillin. Yeast is a type of fungus, and the penicillin-producing fungus is commonly known as Penicillium.

2. **Classify Yeast**: Yeast is classified as a unicellular fungus. It belongs to the group of fungi known as Ascomycetes.

3. **Understand Ascomycetes**: Ascomycetes, also known as sac fungi or spore shooters, are characterized by the production of microscopic spores in specialized structures called asci. This group includes various fungi, including yeast and Penicillium.

4. **Review Other Options**: The question provides other classifications such as Basidiomycetes, Lichomycetes, and Zygomycetes.
- Basidiomycetes include mushrooms and are not the correct classification for yeast and Penicillium.
- Lichomycetes refers to a group that includes pin molds, which also do not include yeast or Penicillium.
- Zygomycetes includes molds like Rhizopus, which is not related to yeast or Penicillium.

5. **Conclusion**: Since both yeast and the penicillin-producing fungus (Penicillium) belong to the Ascomycetes group, the correct answer is Ascomycetes.

**Final Answer**: Yeast and Penicillium/penicillin producing fungus are included under Ascomycetes.
