Study Chapter Details
UP Board Class 11 Biology – Biological Classification
“Biological Classification” is an important chapter in UP Board Class 11 Biology that explains how scientists organize the vast diversity of living organisms into systematic groups. The chapter introduces the Five Kingdom Classification proposed by R.H. Whittaker, which includes Monera, Protista, Fungi, Plantae, and Animalia. Each kingdom is explained on the basis of cell structure, mode of nutrition, reproduction, habitat, and organization levels.
Students learn about prokaryotic and eukaryotic organisms, unicellular and multicellular life forms, and different modes of nutrition such as autotrophic and heterotrophic. The chapter also covers important groups like bacteria, cyanobacteria, protozoa, algae, fungi, and their ecological roles.
This chapter helps learners understand how classification simplifies the study of millions of species and provides clarity about evolutionary relationships. It forms the foundation for advanced biological studies and is highly useful for competitive exams like NEET and CUET.
