B) Alternaria

C) Colletotricum

D) All the above

Show Answer

Answer:

Correct Answer: D

Solution:

The term “Fungi Imperfecti” or “Deuteromycota” is used to describe fungi that do not fit into the commonly established taxonomic classifications of fungi that are based on the structures used in sexual reproduction. This is because their sexual form of reproduction has either not been observed or does not exist.

Option A) Fusarium: Fusarium is a genus of fungi widely distributed in soil and associated with plants. Most species are harmless saprobes, and are relatively abundant members of the soil microbial community. Some species produce mycotoxins in cereal crops that can affect human and animal health if they enter the food chain.

Option B) Alternaria: Alternaria is a genus of ascomycete fungi. Alternaria species are known as major plant pathogens. They are also common allergens in humans, growing indoors and causing hay fever or hypersensitivity reactions that sometimes lead to asthma.

Option C) Colletotrichum: Colletotrichum is a genus of fungi that are plant pathogens. They cause diseases in many types of plants, which can lead to significant crop losses.

All these fungi are part of the group known as Fungi Imperfecti or Deuteromycota because their sexual form of reproduction has not been observed. Therefore, the correct answer is D) All the above.
