• B.
  All of the above
  
• C.
  Mode of spore formation
  
• D.
  Morphology of mycelium to class
  

Answer 1

The correct option is B

All of the above

Classification of kingdom Fungi

• The members of kingdom Fungi are classified into four classes based on the morphology of mycelium, mode of spore formation, and fruiting body.

• These classes are Deuteromycetes, Phycomycetes, Ascomycetes, and Basidiomycetes.

Classification based on morphology of mycelium

• The classification is based on the morphology of mycelium.

• In Phycomycetes, the hyphae of fungi are without septa i.e. aseptate mycelium.

• Ascomycetes, Basidiomycetes, and Deuteromycetes have septate mycelium.

Classification based on spore formation

• Fungi are classified based on the whether the mode of spore formation is sexual or asexual.

• The spores formed by sexual reproduction in Phycomycetes, Ascomycetes, and Basidiomycetes are zygospores, ascospores, and basidiospores, respectively.

• There is an absence of sexual phase in Deuteromycetes. Class Phycomycetes also produce spores asexually called sporangiospores, whereas the class Ascomycetes, Basidiomycetes, and Deuteromycetes produce conidiospores.

Classification based on fruiting bodies

• The fruiting bodies are the sporophytes in which spores are formed during reproduction.

• The fruiting bodies of Phycomycetes, Ascomycetes, and Basidiomycetes are called sporocarp, ascocarp, and basidiocarp respectively.
