“The Living World” is the first chapter of UP Board Class 11 Biology, introducing students to the fundamental characteristics of life. The chapter explains what makes an organism “living” by discussing key features such as growth, reproduction, metabolism, response to stimuli, and cellular organization. Students also learn about biodiversity, its importance, and the need for scientific classification to study the vast variety of life forms on Earth.
This chapter highlights the three domains of life, the significance of nomenclature, and the rules set by ICZN and ICBN for naming organisms. Through examples and classification systems, learners gain clarity on taxonomy, taxonomic hierarchy, and taxonomic aids like herbarium, museum, botanical garden, and zoological park.
“The Living World” builds the base for advanced biological concepts and strengthens students’ understanding of living organisms, their diversity, and systematic study.
