Karnataka Board Class 12 Biology Syllabus

Karnataka PUC Board (KSEEB) Class 12 Biology Syllabus – Latest 2022-2023

Karnataka Board regulates the students’ complete KSEEB Class 12 Biology Syllabus, which is available on our website. The syllabus offers a comprehensive learning experience for students who wish to pursue a career in the Medical sector. Learning the basics of Biology concepts and building a strong foundation in the subject is necessary. The syllabus offers a learning environment where students can understand the concepts and build an understanding.

Biology is considered one of the most important aspects of life, and its study can help solve many problems related to life and living organisms. The study of Biology is relevant to the students planning careers in medical, agriculture, and science fields as well as in other fields of research such as medicine, biotechnology, genetics, population health etc., which are required by students who wish to pursue studies in these fields. 

The KSEEB Class 12 Biology Syllabus introduces many concepts such as organic chemistry and biotechnology, human physiology and nutrition, cell biology, genetics, animals and plants. Physical development of living organisms. The concept of evolution. Factors leading to the origin of life. The steps involved in the biological evolution process and molecular structure involve biodiversity conservation methods. However, learning these concepts is not enough. Students need to practise different types of questions. Therefore, students can refer to the KSEEB previous year’s question paper and KSEEB sample question paper.

1. What is the KSEEB Class 12 Biology Syllabus?

The KSEEB Class 12 Biology syllabus prescribes a list of topics to be taught in the class. These topics are based on the 10+1+3 model. The list of topics is divided into the following chapters and subsections –

  • Overview of Biology
  • Cell Biology
  • Molecular Biology
  • Gene Expression and Regulation in Eukaryotes
  • Principles of Population Genetics and Evolutionary Genetics 
  • Principles of Ecology 
  • Animal Diversity – Plant Diversity – Human Diversity 
  • Plant Nutrition and Photosynthesis – Animal Nutrition: Definition, Processing, Absorption, Utilisation

2. How to get better grades in Class 12?

The following points are the most important tips to achieve better results in your exams:

  • Pay equal attention to all topics. 
  • Follow the KSEEB Class 12 Biology Notes and Class 12 Biology Model papers religiously. 
  • Do not get disheartened if a timely revision of your notes does not yield good grades in the first couple of attempts.
  • Never underestimate the value of the sample paper and the previous year’s question paper.

3. What can we learn from the chapter "Cell Biology"?

The chapter “Cell Biology” discusses the cells that make up the human body. It discusses cell differentiation and how cells cycle through an organism’s life. The chapter also explains how different cells function in each region of the body, from organs to skin, to hair. The human body is made up of many different types of cells, each with a distinct role on an individual and a global level. Students will learn more about the many types of cells in the body and how they work together to maintain life.
