FAQs on Audio Notes: Biological Classification Video Lecture - Biology Class 11 - NEET

1. What is biological classification and why is it important in biology?
Ans.Biological classification, also known as taxonomy, is the science of categorizing living organisms into groups based on shared characteristics. This system allows scientists to organize and identify the vast diversity of life on Earth. The importance of biological classification lies in its utility for understanding relationships among species, facilitating communication about organisms, and aiding in the study of biology, ecology, and conservation efforts.
2. Who is considered the father of modern taxonomy?
Ans.Carl Linnaeus is considered the father of modern taxonomy. He developed the binomial nomenclature system, which assigns each species a two-part scientific name consisting of the genus and species. This system, introduced in the 18th century, is still in use today and provides a standardized way to name and classify organisms.
3. What are the main ranks in the hierarchical system of classification?
Ans.The hierarchical system of classification consists of several main ranks, including domain, kingdom, phylum, class, order, family, genus, and species. This system organizes life forms from the broadest category (domain) to the most specific (species), making it easier for scientists to study and understand the relationships between different organisms.
4. How does the binomial nomenclature system work?
Ans.The binomial nomenclature system is a two-part naming system for organisms. The first part of the name indicates the genus to which the organism belongs, while the second part identifies the species. For example, in the name Homo sapiens, Homo is the genus, and sapiens is the species. This system helps avoid confusion caused by common names and ensures that each organism has a unique scientific name.
5. What are the different domains in the three-domain system of classification?
Ans.The three-domain system of classification consists of Archaea, Bacteria, and Eukarya. Archaea includes prokaryotic organisms that often thrive in extreme environments, Bacteria encompasses true bacteria, and Eukarya includes all eukaryotic organisms, which have complex cells with a nucleus. This system reflects the evolutionary relationships among these groups and highlights the differences in cellular organization.
