FAQs on Neet : MCQ on Living Organisms (taxonomy) - Class 12

1. What is taxonomy and why is it important in the study of living organisms?
Ans. Taxonomy is the science of classification, identification, and naming of living organisms. It is important in the study of living organisms as it helps in organizing and categorizing them into different groups based on their similarities and differences. This allows scientists to understand the relationships between different species, study their characteristics, and make predictions about their behavior and evolution.
2. What are the different levels of classification in taxonomy?
Ans. The different levels of classification in taxonomy, from broadest to most specific, are: kingdom, phylum, class, order, family, genus, and species. These levels help in organizing and categorizing living organisms based on their shared characteristics and evolutionary relationships.
3. How are living organisms classified into different kingdoms?
Ans. Living organisms are classified into different kingdoms based on their cellular organization, mode of nutrition, and other characteristics. The five main kingdoms are: Monera (unicellular prokaryotes), Protista (unicellular eukaryotes), Fungi (multicellular eukaryotes that absorb nutrients), Plantae (multicellular eukaryotes that perform photosynthesis), and Animalia (multicellular eukaryotes that ingest food).
4. What is the importance of binomial nomenclature in taxonomy?
Ans. Binomial nomenclature is a naming system in taxonomy that assigns a unique scientific name to each species. It consists of two parts: the genus name and the species name. This system is important as it provides a standardized way of naming and referring to organisms, regardless of the language or region. It helps in avoiding confusion and ensures clear communication among scientists studying living organisms.
5. How does taxonomy contribute to our understanding of biodiversity?
Ans. Taxonomy plays a crucial role in understanding biodiversity by providing a framework to study and organize the vast variety of living organisms on Earth. By classifying and categorizing species, taxonomists can identify new species, assess their distribution, and study their ecological roles. This knowledge is essential for conservation efforts, as it helps in identifying species at risk and understanding their relationships within ecosystems. Additionally, taxonomy allows scientists to track and analyze changes in biodiversity over time, aiding in the understanding of environmental changes and their impacts on living organisms.
