Which of the following statement is true about fungi imperfecti

Options

A. They do not have sexual phase
B. They include toad stools , puff balls and stink horns
C. They do not include Aspergillus , the fungus used in making soya sauce
D. They include species that prey on nematodes.

Answer

To determine which statement is true about fungi imperfecti (Deuteromycetes), we can analyze each option provided:

1. **Statement Analysis**:
- **Option 1**: "They do not have a sexual phase."
- This statement is true. Fungi imperfecti, or Deuteromycetes, are characterized by their lack of a known sexual reproductive stage. They primarily reproduce asexually through conidia.

- **Option 2**: "They include toadstools, puffballs, and stinkhorns."
- This statement is false. Toadstools, puffballs, and stinkhorns belong to the class Basidiomycetes, not Deuteromycetes.

- **Option 3**: "They do not include Aspergillus, the fungus used in making soya sauce."
- This statement is also false. Aspergillus is indeed a member of the Deuteromycetes and is used in the fermentation process for making soya sauce.

- **Option 4**: "They include species that prey on nematodes."
- This statement is incorrect. While some fungi do prey on nematodes, this characteristic is not typical of Deuteromycetes.

2. **Conclusion**:
- Based on the analysis, the correct statement about fungi imperfecti is **Option 1**: "They do not have a sexual phase."
