Biology is a vast subject that covers various topics, including genetics, ecology, plant and animal physiology, evolution, and more. While preparing for exams, it is essential to know the weightage of each chapter to plan your study schedule effectively. In this guide, we will discuss the bio chapters and their weightage in the exam.



Here are the chapters and their weightage for the bio exam:

• Cell Biology: Cell biology is a crucial topic, as it forms the foundation of the entire subject. It covers topics such as cell structure, organelles, functions, and more. The weightage of this chapter in the exam is around 10-15%.



• Genetics: Genetics is the study of genes and heredity. It includes topics such as Mendelian genetics, molecular genetics, genetic disorders, and more. The weightage of this chapter in the exam is around 15-20%.



• Ecology: Ecology is the study of interactions between organisms and their environment. It includes topics such as ecosystem, food chain, biodiversity, and more. The weightage of this chapter in the exam is around 10-15%.



• Plant Physiology: Plant physiology is the study of how plants function and grow. It includes topics such as photosynthesis, respiration, growth and development, and more. The weightage of this chapter in the exam is around 10-15%.



• Animal Physiology: Animal physiology is the study of how animals function and adapt to their environment. It includes topics such as digestion, circulation, excretion, and more. The weightage of this chapter in the exam is around 10-15%.



• Evolution: Evolution is the study of how species change over time. It includes topics such as natural selection, adaptation, speciation, and more. The weightage of this chapter in the exam is around 10-15%.



• Biotechnology: Biotechnology is the application of biological principles to develop new products and technologies. It includes topics such as genetic engineering, bioremediation, and more. The weightage of this chapter in the exam is around 5-10%.



• Human Health and Diseases: Human health and diseases cover topics such as communicable and non-communicable diseases, immunity, and more. The weightage of this chapter in the exam is around 5-10%.

Knowing the weightage of each chapter is essential to plan your study schedule effectively. Focus on the chapters with higher weightage, but do not neglect the other chapters. Remember to revise regularly and practice solving previous year question papers to prepare well for the exam.
