Question:

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

Options:

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 algae and a protozoan
3. Yeast used in making bread and beer is a fungus
4. _Nostoc_ and _Anabaena_ are examples of Protista

Solution:

(3) Yeast or saccharomyces cerevisiae is a fungus of class-Ascomycetes. Saccharomyces sp. are widely used in baking and brewing industries. Paramecium and Plasmodium belong to kingdom-Protista, Penicillium belongs to kingdom-fungi. Lichen is a composite organism formed from the symbiotic association of algae and fungi. _Nostoc_ and _Anabaena_ are examples of cyanobacteria or blue-green algae.
