In about 20 out of 15000 species of lichens, the fungal partner is:
Correct answer: A. Ascomycetes
- A. Ascomycetes
- B. Zygomycetes
- C. Basidiomycetes
- D. Imperfect fungi
Explanation
In lichens, the fungal partner is usually an Ascomycete, which forms a symbiotic relationship with an algal or cyanobacterial partner. Although Basidiomycetes can also form lichens, this is much less common. Zygomycetes and imperfect fungi are not typically involved in lichen formation, with Ascomycetes being the dominant group in the vast majority of lichen species.
