Prepare for NEET with Botany-specific practice questions. Covering all major Botany chapters, this is perfect for your NEET Biology needs.
While creating a phylogenetic tree for a genus of insects, a taxonomist finds conflicting information between a recently published monograph and a classical museum catalogue. Which resource should be prioritized and why?
The museum catalogue, due to its historical precedence and established nomenclature.
The monograph, as it likely incorporates newer molecular data and revised classifications.
Equal weight to both, synthesizing the information.
Neither, consult a field guide for practical identification.
A taxonomist discovers a new species of insect. Phylogenetic analysis places it within the order Coleoptera, but its morphology is so unique it warrants a new family. Which of the following taxonomic ranks will not necessarily be assigned a new name for this insect?
Order
Family
Genus
Species
The polyphyletic grouping of organisms is based on:
Shared ancestral characteristics.
Homologous characteristics derived from a common ancestor.
Analogous characteristics due to convergent evolution.
A combination of ancestral and derived characteristics.
Which of the following is not a limitation of classical taxonomy?
It relies heavily on morphological characteristics, which can be subject to convergent evolution.
It may not accurately reflect evolutionary relationships.
It can be difficult to distinguish between homologous and analogous traits.
It incorporates molecular data for a more comprehensive analysis.
A scientist is constructing a phylogenetic tree using cladistics. Which type of character would be considered the most informative for resolving evolutionary relationships within a group?
Plesiomorphy
Symplesiomorphy
Autapomorphy
Synapomorphy
Systematics includes:
Only taxonomy
Only identification
Taxonomy, evolutionary relationships, and phylogenetic classification
Only nomenclature
Biosystematics aims at
The classification of organism based on their evolutionary history and establishing their phylogeny on the totality of various parameters from all fields of studies
Identification and arrangements of organism on the basis of their cytological characteristics
The classification of organisms based on broad morphological characters
Delimiting various taxa of organisms and establishing their relationships
In which of the following, all listed genera belong to the same class of algae?
Chara,Fucus,Polysiphonia
Volvox,Spirogyra,Chlamydomonas
Porphyra,Ectocarpus,Ulothrix
Sargassum,Laminaria,Gracillaria

Select the incorrect statement
In multicellular organism growth and reproduction are not synonymous
A scientific name should be printed in italics according to binomical nomenclature
A museum has preserved plant and animals specimens
Taxonomy includes phylogeny as the basis of classification of orgnamisms
