FAQs on Short Tricks: Biological Classification Tables Video Lecture - Biology Class 11 - NEET

1. What is the importance of biological classification in NEET?
Ans. Biological classification is an essential topic in NEET as it helps in understanding the diversity of living organisms. It enables students to categorize and organize different organisms based on their similarities and differences. This classification system aids in the identification, naming, and study of various species, thereby forming the foundation for studying evolutionary relationships and ecological interactions among organisms.
2. How many levels of classification are there in the biological classification system?
Ans. The biological classification system consists of seven levels of classification, namely Kingdom, Phylum, Class, Order, Family, Genus, and Species. These levels, collectively known as the taxonomic hierarchy, help in the systematic classification of organisms based on their shared characteristics and evolutionary relationships.
3. What are the main criteria used for classifying organisms in biological classification?
Ans. Organisms are classified based on several criteria, including their cell type (prokaryotic or eukaryotic), cellular organization (unicellular or multicellular), mode of nutrition (autotrophs or heterotrophs), body symmetry, presence or absence of a backbone, and reproductive methods. These criteria help in categorizing organisms into different groups and subgroups, providing a systematic approach to studying and understanding the diversity of life forms.
4. How does biological classification aid in the study of evolutionary relationships?
Ans. Biological classification allows us to identify and group organisms based on their shared characteristics and evolutionary history. By examining the similarities and differences between different species, scientists can infer evolutionary relationships and construct phylogenetic trees. These trees depict the evolutionary history and common ancestry of organisms, helping us understand how different species have evolved over time.
5. Can you provide an example of biological classification in action?
Ans. An example of biological classification is the classification of humans. Humans belong to the Kingdom Animalia, Phylum Chordata, Class Mammalia, Order Primates, Family Hominidae, Genus Homo, and Species sapiens. This classification system allows us to identify humans as a distinct species within the animal kingdom and understand their evolutionary relationships with other primates.
