NEET Questions / Botany / Diversity in Living World / Taxonomic Categories
A taxonomist is studying a newly discovered organism. They find it to be eukaryotic, multicellular, heterotrophic, with chitinous cell walls and exhibiting absorptive nutrition. Based solely on these characteristics, to which of the following taxonomic groups could the organism most precisely be assigned?
Kingdom Fungi
Phylum Basidiomycota
Domain Eukarya
Class Ascomycetes
While classifying organisms, which of the following presents the biggest challenge to a strictly phylogenetic system of classification?
Convergent evolution
Horizontal gene transfer
Fossil record incompleteness
Morphological similarities in unrelated species
Consider the hierarchical categories: Family, Order, Genus, and Species. Which represents the most inclusive category followed by the most exclusive in the correct order?
Genus, Family
Family, Species
Order, Species
Species, Order
Which statement correctly explains the relationship between taxonomic categories and phylogenetic classification?
Taxonomic categories are arbitrary and have no relationship to phylogeny.
Taxonomic categories always perfectly match the branching patterns of phylogenetic trees.
Taxonomic categories ideally reflect evolutionary relationships revealed through phylogenetic analysis.
Phylogenetic analysis is used to create taxonomic categories, but they don't necessarily reflect evolutionary relationships.
Polyphyletic groups are problematic in taxonomy because they:
Include all descendants of a common ancestor.
Include the most recent common ancestor and all its descendants.
Do not include the most recent common ancestor of all members.
Represent a single evolutionary lineage.
Which of the following is not a valid reason why the morphological species concept can be problematic?
It can be difficult to distinguish between intraspecific variation and interspecific differences.
Cryptic species may be morphologically identical but reproductively isolated.
It requires detailed genetic analysis.
Morphological traits can be influenced by environmental factors leading to phenotypic plasticity.
Which of the following taxonomic categories represents the highest level of diversity?
Phylum
Class
Kingdom
Order
A taxon is:
Specifically a group of species
Only used for plants
A group of organisms at any level of taxonomic hierarchy
Only used for animals
Which taxonomic category is immediately below 'Class' in the hierarchical classification?
Family
Genus
Order
Phylum
Which of these represents the correct hierarchical sequence (from broader to narrower)?
Order, Class, Phylum
Class, Phylum, Order
Phylum, Class, Order
Order, Phylum, Class
