KCET Biology Syllabus 2026 – Chapter-wise List
KCET Biology tests all chapters from both 1st PUC and 2nd PUC as per the official Karnataka blueprint.
| 1st PUC Chapters (Class 11) | 2nd PUC Chapters (Class 12) |
| The Living World | Sexual Reproduction in Flowering Plants |
| Biological Classification | Human Reproduction |
| Plant Kingdom | Reproductive Health |
| Animal Kingdom | Principles of Inheritance and Variation |
| Morphology of Flowering Plants | Molecular Basis of Inheritance |
| Anatomy of Flowering Plants | Evolution |
| Structural Organisation in Animals | Human Health and Disease |
| Cell: The Unit of Life | Microbes in Human Welfare |
| Biomolecules | Biotechnology: Principles and Processes |
| Cell Cycle and Cell Division | Biotechnology and Its Applications |
| Transport in Plants | Organisms and Populations |
| Mineral Nutrition | Ecosystem |
| Photosynthesis in Higher Plants | Biodiversity and Conservation |
| Respiration in Plants | |
| Plant Growth and Development | |
| Digestion and Absorption | |
| Breathing and Exchange of Gases | |
| Body Fluids and Circulation | |
| Excretory Products and Elimination | |
| Locomotion and Movement | |
| Neural Control and Coordination | |
| Chemical Coordination and Integration |
All chapters are important, but 2nd PUC topics such as Genetics, Molecular Biology, and Human Reproduction carry more weight. Meanwhile, 1st PUC chapters like Cell Biology and Physiology build your foundation and should not be skipped.

Inheritance topics has the highest weightage, making it the most important topic in KCET Biology.
How to Prepare KCET Biology
- Focus on 2nd PUC first Focus first on Genetics and Molecular Biology. These chapters can make a big difference in your rank. Refer to the 2nd PUC Biology syllabus for complete chapter coverage.
- Strengthen 1st PUC fundamentals Cell Biology, Plant Physiology, and Human Physiology are tested often and help you understand more advanced topics. The 1st PUC Biology syllabus covers all the foundational chapters you need.
- Use NEET overlap smartly KCET Biology has a lot in common with NEET. If you are preparing for both, stick closely to NCERT and practice MCQs often.
A Quick Word on Preparation Support
Many students who study Biology for KCET also prepare for NEET or other entrance exams. Having structured guidance can really help in these cases.
At Giraffe Learning, students get clear study plans, regular tests, and focused preparation for each subject based on the KCET pattern. The method is simple: build your concepts first, then work on speed and accuracy with practice.
If you want help instead of studying alone, CET coaching can keep you consistent and on track.
Frequently Asked Questions about Kcet Biology
