NEET Biology 2026 Chapters List: Weightage & Strategic Analysis
The NEET Biology 2026 chapters list includes all important topics with chapter-wise weightage and strategic analysis. It helps aspirants prioritize high-scoring chapters, focus on key concepts, and plan effective preparation for the exam.
For any NEET (UG) 2026 aspirant, Biology isn't just a subject—it's the backbone of your score. With 90 questions contributing a massive 360 marks, mastering the NEET Biology 2026 Chapters List is the most efficient way to cross the 650+ mark threshold.
Rather than treating every chapter equally, high-scoring students use a weightage-based approach. Below is the comprehensive breakdown of the Biology chapters categorized by their impact on the 2026 exam.
The "High-Yield" Powerhouse Chapters
These chapters are the heavy hitters. Historically, they contribute nearly 40–50% of the total Biology questions. If you are short on time, these are the "Do-or-Die" topics.
| "High-Yield" Powerhouse Chapters | ||
| Unit | Top Chapters | Expected Questions |
| Genetics & Evolution | Molecular Basis of Inheritance, Principles of Inheritance | 10–12 |
| Human Physiology | Circulatory System, Nervous System, Chemical Coordination | 12–15 |
| Biotechnology | Principles & Processes, Applications | 8–10 |
| Diversity | Animal Kingdom, Biological Classification | 8–9 |
| Cell Biology | Cell Cycle and Cell Division, Cell: The Unit of Life | 7–8 |
Complete NEET Biology 2026 Chapter List (Botany & Zoology)
The syllabus is broadly divided into Botany (Plant Science) and Zoology (Animal Science). While some overlap exists (like Genetics and Cell Biology), here is the streamlined list of chapters you must cover:
Class 11 Chapters (Foundation)
-
The Living World: Basic taxonomy and nomenclature.
-
Biological Classification: Focus on Monera, Protista, and Fungi.
-
Plant Kingdom: Algae, Bryophytes, Pteridophytes, Gymnosperms, and Angiosperms.
-
Animal Kingdom: Classification from Porifera to Chordata.
-
Morphology & Anatomy of Flowering Plants: Root, stem, leaf modifications, and tissue systems.
-
Structural Organisation in Animals: Animal tissues and Cockroach/Frog anatomy.
-
Cell - The Unit of Life: Organelles and their functions.
-
Biomolecules: Enzymes, proteins, and nucleic acids.
-
Plant Physiology: Photosynthesis, Respiration, and Plant Growth.
-
Human Physiology: Digestion, Breathing, Circulation, Excretion, Locomotion, and Neural Control.
Class 12 Chapters (Advanced Concepts)
-
Sexual Reproduction in Flowering Plants: Pollination and Fertilization.
-
Human Reproduction & Reproductive Health: Male/Female systems and contraception.
-
Genetics: Mendelian inheritance and Molecular Biology (DNA/RNA).
-
Evolution: Origin of life and Darwinian theories.
-
Human Health and Disease: Immunity, AIDS, Cancer, and common pathogens.
-
Microbes in Human Welfare: Sewage treatment and household products.
-
Biotechnology: Recombinant DNA technology and its medical/agricultural uses.
-
Ecology: Organisms, Populations, Ecosystems, and Biodiversity.
Strategic Analysis: Botany vs. Zoology
-
Zoology (Approx. 55% weightage): Generally considered more scoring as questions are often direct. Human Physiology and Animal Kingdom are the anchors here.
-
Botany (Approx. 45% weightage): Requires strong conceptual clarity, especially in Plant Physiology and Genetics.
Pro-Tips for NEET 2026 Success
-
NCERT is the Bible: In recent years, 95% of Biology questions have been framed directly from NCERT lines. Read the summaries and "Points to Ponder" sections carefully.
-
Focus on Diagrams: Labeling-based questions are a favorite for the NTA. Ensure you can identify every part of the diagrams in the NCERT.
-
Master the PYQs: Solving the last 10 years of Previous Year Questions (PYQs) will help you identify the "trap" options that examiners often use.
-
Flowcharts for Physiology: Instead of long notes, use flowcharts to remember the Cardiac Cycle, Oxygen Dissociation Curve, and Hormonal Feedback loops
