Class 11 Biology (NCERT)
NCERT's Class 11 Biology textbook, explained through scientists' stories and hands-on activities rather than lists of facts. See how living things are named, classified and connected, and how biology links with physics and chemistry.
The Living World
Chapter 1
Chapter 1 · Start here
The Living World
Why there are so many kinds of living things, and how scientists name, classify and arrange them into a hierarchy.
Sprint 1
Naming The Living World
Why every living thing needs one scientific name, and the rules of binomial nomenclature.
Sprint 2
Taxonomy And Systematics
Classification, taxonomy and systematics: how they differ, and what a taxon is.
Sprint 3
The Taxonomic Hierarchy
The ranks from species to kingdom, and how shared features change as you move up.
Sprint 4
Review: The Living World
Put naming, taxonomy and the hierarchy together, and test yourself.
Biological Classification
Chapter 2
Chapter 2 · Start here
Biological Classification
The five kingdoms of life, from bacteria and protists to fungi, and what doesn't fit neatly: viruses, viroids, prions and lichens.
Sprint 5
The Five Kingdom System
Understand Whittaker's criteria for the Five Kingdom Classification and the characteristics of each.
Sprint 6
Kingdom Monera: The Bacteria
Identify bacterial shapes, recognize the metabolic diversity of bacteria, and distinguish Archaebacteria, Eubacteria, and Mycoplasma.
Sprint 7
Kingdom Protista: The Unicellular Eukaryotes
Classify Protists into their five major groups and describe their distinct structural and ecological features.
Sprint 8
Kingdom Fungi
Understand fungal morphology, the sexual reproduction cycle (including dikaryophase), and classify the four fungal classes.
Sprint 9
Beyond The Five Kingdoms
Define the boundaries of life by examining Plantae/Animalia briefly, and exploring viruses, viroids, prions, and lichens deeply.
Sprint 10
Chapter Review: Biological Classification
Synthesize chapter concepts, test deep recall, and apply understanding to descriptive questions.
Plant Kingdom
Chapter 3
Chapter 3 · Start here
Plant Kingdom
How plants are classified, from algae and mosses to ferns, gymnosperms and flowering plants.
Sprint 11
Systems Of Classification & Taxonomy
Distinguish between artificial, natural, and phylogenetic classification, and understand modern taxonomic methods.
Sprint 12
Algae: The Primary Producers
Understand the features, economic importance, and three main classes of Algae.
Sprint 13
Bryophytes: Amphibians Of The Plant Kingdom
Understand the life cycle, habitat, and two main types of bryophytes (Liverworts and Mosses).
Sprint 14
Pteridophytes: The First Vascular Plants
Understand pteridophyte structure, their dominant sporophyte phase, and the evolutionary significance of heterospory.
Sprint 15
Gymnosperms & Angiosperms: The Seed Plants
Compare gymnosperms (naked seeds) and angiosperms (enclosed seeds) and understand their reproductive strategies.
Sprint 16
Chapter Review
Synthesize chapter concepts, test vocabulary, and apply knowledge to varied question formats.
