Biology carries half the NEET paper, so knowing exactly what is in and out of the syllabus matters more here than anywhere else. This NEET 2027 Biology syllabus guide gives you all 10 NMC units, the 32 matching NCERT chapters, a free PYQ link for every chapter, and clear answers to the “is this topic in the syllabus?” questions students search for most.
For subject strategy, read our complete NEET Biology strategy. Use this page as your chapter checklist.
Every chapter in the tables below links straight to its previous year questions, starting with The Living World PYQs, so you can move from syllabus to practice in one click.

Has the NEET 2027 Biology Syllabus Been Released?
Not yet. The National Medical Commission (NMC) released the NEET 2026 syllabus on 23 December 2025, with no changes from 2025. Until the 2027 version is published, the NEET 2026 Biology syllabus is the one to follow.
Big changes are unlikely, because NCERT is keeping the same Class 11 and 12 textbooks for 2026–27. We explain why in our guide on what could change for 2027.
Biology Syllabus at a Glance
- Units: 10 (5 from Class 11 and 5 from Class 12)
- NCERT chapters covered: 32 (19 from Class 11 and 13 from Class 12)
- Questions in the paper: 90 Biology questions (45 Botany and 45 Zoology), 360 marks, based on the current pattern
- Base: almost every question comes from NCERT text, diagrams and examples
Is This Topic in the NEET 2027 Biology Syllabus?
These answers are based on the current NMC syllabus and its list of deleted topics.

Biology Chapter Wise Weightage: Where to Focus
Exact numbers change every year, but recent papers show a steady pattern. Use this biology chapter wise weightage as a priority guide, and see our NEET 2027 chapter weightage page for the full breakdown.
| Priority | Units |
|---|---|
| High | Human Physiology, Genetics and Evolution, Ecology and Environment, Reproduction, Diversity in the Living World |
| Medium | Cell Structure and Function, Structural Organisation, Biotechnology, Plant Physiology |
| Lower | Biology and Human Welfare |
Human Physiology is the single biggest block, and our Human Physiology guide covers it chapter by chapter. For Botany, see our complete NEET Botany guide. To pick one reference book beyond NCERT, see the best Biology reference books.

|---|---|---|
| 6 | Reproduction | Sexual Reproduction in Flowering Plants, Human Reproduction, Reproductive Health |
| 7 | Genetics and Evolution | Principles of Inheritance and Variation, Molecular Basis of Inheritance, Evolution |

The Plant Families Many Students Miss
The NMC syllabus names five flowering plant families under Structural Organisation: Malvaceae, Cruciferae, Leguminosae, Compositae and Gramineae. The current NCERT chapter describes Fabaceae (another name for Leguminosae), Solanaceae and Liliaceae.
Learn the floral formula, floral diagram and two or three examples for each family named in the syllabus. This is a small topic, but questions on it are direct and easy to score once you know it.
How to Use This Syllabus With PYQs
- Print the two tables above and tick each chapter as you finish it.
- After each chapter, solve its PYQs using the links in the table. This shows exactly how NTA tests it.
- Read NCERT line by line. Most Biology questions are taken directly from NCERT sentences, tables and diagrams.
- Revise diagrams every week, especially in Human Physiology, Reproduction and Plant Anatomy.
- Cover the high-weightage units first if you are short on time.
NEET biology PYQs are the most reliable guide to question style. Two rounds of chapter-wise PYQs, done alongside NCERT reading, usually lift Biology scores more than any extra book.

Conclusion
The NEET 2027 Biology syllabus is expected to keep the same 10 units and 32 NCERT chapters as 2026. Skip the removed topics, learn the five plant families the syllabus names, give extra time to the high-weightage units, and pair every chapter with its PYQs. When NMC releases the official document, compare it with this list, and you will know within minutes if anything has changed.
