Which one single organism or the pair of organisms is correctly assigned to its or their named taxonomic group?

  1. Paramecium and Plasmodium belong to the same kingdom as that of Penicillium.
  2. Lichen is a composite organism formed from the symbiotic association of an alga and a protozoan.
  3. Yeast used in making bread and beer is a fungus.
  4. Nostoc and Anabaena are examples of protista.

Answer

(3) Yeast used in making bread and beer is a fungus.

Solution

(1) Paramecium and Plasmodium are protozoans (Protista), whereas Penicillium is a fungus ⇒ incorrect.

(2) As per NCERT, lichens are symbiotic associations between algae and fungi ⇒ incorrect.

(3) Yeast ( Saccharomyces), used in making bread and beer, is a unicellular fungus (Ascomycetes) ⇒ correct.

(4) Nostoc and Anabaena are cyanobacteria (Monera) ⇒ incorrect.

Answer: (3)
