Q-1: What is Taxonomy?
Ans- Taxonomy is the scientific study of classifying based on shared characteristics, naming them systematically, and placing them into a hierarchical structure, forming the foundation of biosystematics and biodiversity studies.
Q-2: Define biosystematics.
Ans. Biosystematics integrates taxonomy with evolutionary biology, genetics, and ecology to understand organismal relationships, variations, and speciation, providing insights into natural classification and the evolutionary basis of biodiversity.
Q-3. What is the basic concept of taxonomy?
Ans. The basic concept of taxonomy involves identifying, naming, and classifying organisms systematically based on morphology, genetics, and ecological attributes, ensuring consistency, universality, and scientific communication in biological studies.
Q-4. Who is considered the father of taxonomy?
Ans. Carolus Linnaeus, an 18th-century Swedish botanist, is recognized as the father of taxonomy for developing binomial nomenclature and introducing hierarchical classification, which remains foundational in modern biosystematics.

Q-5. What is binomial nomenclature?
Ans. Binomial nomenclature is a system of naming species with two Latin names: genus and species, providing a universal, standardized, and internationally recognized method for identifying and cataloging organisms.
Q.6. Explain the history of biosystematics?
Ans. Biosystematics evolved from classical taxonomy, incorporating genetics, cytology, and ecology, progressing from descriptive classification to modern integrative approaches, emphasizing evolutionary relationships, species concepts, and biodiversity assessment.
Q.7. What is the scope of biosystematics?
Ans. The scope of biosystematics includes species identification, phylogenetic analysis, evolutionary studies, conservation planning, and biodiversity management, bridging taxonomy with genetics, ecology, and molecular biology to understand life forms comprehensively.
Q.8. Mention applications of biosystematics?
Ans. Biosystematics applications include agriculture, conservation, disease management, ecological monitoring, evolutionary research, biodiversity cataloging, forensic studies, and understanding genetic diversity for sustainable utilization of natural resources.Q.9. Define taxonomic diversity?
Ans. Taxonomic diversity refers to the variety of organisms classified at different hierarchical levels, reflecting evolutionary relationships, ecological adaptations, and morphological variations within and between species.Q.10. What are taxonomic categories?
Ans. Taxonomic categories are hierarchical levels used to classify organisms, including domain, kingdom, phylum, class, order, family, genus, and species, facilitating systematic identification, comparison, and understanding of biodiversity.Q.11. Explain micro-taxonomy?
Ans. Micro-taxonomy studies the classification of organisms at lower hierarchical levels, such as species, subspecies, and varieties, focusing on detailed morphological, genetic, and ecological differences within narrowly defined groups.
Q.12. Explain macro-taxonomy?
Ans. Macro-taxonomy involves higher taxonomic levels such as kingdom, phylum, and class, examining broad evolutionary relationships and overarching patterns of organismal diversity across large biological groups.Q.13. What is a species category?
Ans. The species category is the basic unit of classification, defined as a group of interbreeding organisms sharing common characteristics, capable of producing fertile offspring and occupying a specific ecological niche.Q.14. Define subspecies?
Ans. A subspecies is a taxonomic unit below species, representing geographically or ecologically distinct populations with minor morphological or genetic variations, which can interbreed with other subspecies of the same species.Q.15. Mention other intra-species categories?
Ans. Other intra-species categories include varieties, forms, morphs, and races, reflecting minor variations within a species due to genetic, environmental, or adaptive factors without forming separate species.Q.16. What is speciation?
Ans. Speciation is the evolutionary process by which populations diverge to form new species, driven by genetic variation, natural selection, reproductive isolation, and ecological or geographical factors over time.
