Complete Breakdown of the NEET Biology Syllabus
Biology is central to NEET preparation. As 50% of the total marks are covered by Biology, it
is important to grasp the NEET Biology syllabus deeply in order to achieve a good score.
The syllabus includes Botany and Zoology, and nearly all the questions that are asked in
NEET are based on the NCERT. That’s why mastering every line of your NCERT textbooks
is non-negotiable.
At NEET online coaching, we follow a strict line-by-line learning pattern so that nothing is
left out, and you stay fully aligned with the exam's expectations. Biology is also among the
highest-scoring subjects because it requires more understanding rather than memorisation.
When your concepts are ideas and when you revise them on a regular basis, then it is easy
to score 300+ in Biology. Below is a detailed, student-friendly breakdown of the entire
Biology NEET syllabus.
Class 11 Biology Topics
Class 11 builds the foundation of the subject. These chapters will make you realize how life
works at all levels, starting with the small cells and the complex ones. The Biology Full
Syllabus Test for NEET for Class 11 includes:
1. Diversity of Living Organisms
It is the unit that teaches you how to classify millions of species on Earth. You get to know
about the Five Kingdom Classification, the plant and animal taxonomy, and the features of
the various groups. Many questions in the NEET Biology Syllabus PDF are based on basic
definitions and examples.
2. Structural Organisation in Plants and Animals
Here, you learn about tissues, organs, and systems both within a plant and an animal. It
contains animal tissues, morphology, and anatomy of flowering plants, and a more detailed
examination of organ systems in complex organisms.
3. Cell Structure and Function
This is among the concept-heavy chapters. You get to know about cell cycle, cell division,
biomolecules, and the ultrastructure of cells. Questions on mitosis, meiosis, and organelles
are highly frequent in NEET.
4. Plant Physiology
This part details the way in which plants act through photosynthesis, respiration, transport of
plants, growth, and movement. These chapters enhance your knowledge of the plant life
processes.
5. Human Physiology
One of the most important parts of the Class 11 syllabus. It includes digestion, respiration,
circulation, excretion, locomotion, neural control, and chemical coordination. These chapters
help you understand the mechanisms of the human body in depth.
Class 12 Biology Topics
Class 12 offers a significant number of NEET questions as the chapters are full of concepts
and application-oriented. Class 12 NEET Syllabus Biology has:
1. Reproduction
You get to know the way plants and humans reproduce. These are sexual reproduction in
flowering plants, the human reproductive system, gametogenesis, the menstrual cycle, and
reproductive health.
2. Genetics and Evolution
This is a high-weightage section. You learn about Mendelian genetics, inheritance patterns,
DNA, RNA, gene expression, mutations and the theory of evolution as postulated by Darwin.
3. Biology in Human Welfare
Topics covered in this unit include human diseases, immunity, and microbes in food
production. It also covers household applications of bacteria and strategies for enhancing
food production.
4. Biotechnology and Its Applications
A very scoring section of the syllabus. It discusses DNA technology, genetic engineering,
cloning, GM crops, PCR, and biotechnology in medicine and agriculture.
5. Ecology and Environment
This section covers ecosystems, biodiversity, environmental issues, population interactions,
and conservation. The questions in these chapters are usually fact-based and often direct.
How to Study Biology Effectively?
Biology requires consistent reading and understanding, and not rote memorisation. Read the
NCERT multiple times, highlight important lines, and practise NCERT diagrams repeatedly.
The toppers go through Biology 10-12 times before the exam. Always do topic-wise mock
tests to make the recall and accuracy strong.
Why Our Biology Program Helps Students Score High?
With structured notes, revision plans, and 24/7 guidance, NEET Online Coaching ensures
your Biology preparation becomes simple, strong, and completely exam-ready. As we know,
the questions mostly come from the NCERT, so that you might have all the basics clear from
it. But if you are worried about how you can learn everything, then you can rely on our
professionals.
Our animation videos are of high quality and simplify complex concepts for easy visualisation
and retention. Each chapter is taught with real-life examples, flowcharts, diagrams, and
exam-focused explanations so you understand rather than memorise. Students also get
regular doubt-solving sessions, daily practice questions, and weekly mock tests that mirror
the NEET pattern, helping you track improvement consistently.

FAQs
1. How many chapters are there in the NEET Biology syllabus?
The Biology Syllabus for NEET includes 38 chapters, 19 from Class 11 and 19 from Class
12. All the chapters are important owing to the high NCERT-based nature of Biology.
Consistent revision, diagram practice, and NCERT reading are key to scoring well.
2. Is NCERT enough for NEET Biology preparation?
Yes, NCERT is sufficient for NEET Biology. The questions are based on the NCERT lines,
with approximately 95% of them either directly or indirectly. Be careful to read each line,
revise frequently, and improve accuracy by practising NCERT-based mock tests.
3. Which Biology chapters carry the highest weightage in NEET?
The weightage is the heaviest in Genetics, Human Physiology, Ecology, Reproduction and
Biotechnology. These are chapters that are repeated in past year papers. Rebates on these
high-yielding subjects will increase your probability of achieving a score of 300 and above
with ease.
4. How should I revise the NEET Biology syllabus effectively?
Begin with NCERT, take short notes, and revise the NEET Biology Syllabus Chapter
Wise. Seeing flashcards, answering questions from past years, and performing mock tests
regularly. Repeat diagrams and flowcharts since NEET tends to ask questions directly as
NCERT illustrations.
5. How many hours should I study Biology daily for NEET?
A minimum of 2–3 hours of Biology daily is ideal. Concentrate on concepts, reading NCERT
line-by-line, and topic-based questions. Daily revision will keep the information updated and
enhance long-term memory.
6. Are diagrams important for the NEET Biology exam?
Yes, diagrams are extremely important. Bio Syllabus NEET frequently asks diagram-based
questions from the NCERT. You should practice labelling and recalling diagrams from
chapters like plant anatomy, genetics, physiology, and human reproduction.
