For Botany,refer directly to NCERT BIOLOGY XI & XII.Though few chapters need special concentration like Genetics,Photosynthesis in Plants and Respiration in Plants.But,for Rest of the chapters ,go for NCERT as questions are directly from lines of the chapters in NCERT.And ,Examples of NCERT only to be concentrated on.

For Zoology part ,You need to read beyond NCERT for nice score.Chapters like Animal Kingdom , Human physiology ,Human Reproduction ,Evolution should be studied in quite detailed manner.

Hope it helps -:)

There are several chapters in biology beyond NCERT that require additional reading. These chapters are important to gain a deeper understanding of the subject matter and to excel in biology exams. Some of the important chapters that require additional reading are:

Genetics and Evolution
This chapter covers the basics of genetics and evolution, including topics such as Mendelian genetics, the laws of inheritance, and natural selection. To gain a deeper understanding of genetics and evolution, students should read beyond NCERT and focus on topics such as epigenetics, gene regulation, and genetic engineering.

Cell Structure and Function
This chapter covers the basics of cell structure and function, including topics such as organelles, cell membranes, and cellular respiration. To gain a deeper understanding of cell structure and function, students should read beyond NCERT and focus on topics such as cellular signaling, cell cycle regulation, and stem cell biology.

Reproduction
This chapter covers the basics of reproduction, including topics such as sexual and asexual reproduction, fertilization, and embryonic development. To gain a deeper understanding of reproduction, students should read beyond NCERT and focus on topics such as reproductive technologies, reproductive health, and the biology of aging.

Ecology
This chapter covers the basics of ecology, including topics such as ecosystems, biodiversity, and environmental conservation. To gain a deeper understanding of ecology, students should read beyond NCERT and focus on topics such as population dynamics, climate change, and conservation biology.

Human Physiology
This chapter covers the basics of human physiology, including topics such as digestion, respiration, and circulation. To gain a deeper understanding of human physiology, students should read beyond NCERT and focus on topics such as immunology, endocrinology, and neurobiology.

In conclusion, biology is a vast subject, and there are several chapters beyond NCERT that require additional reading. By focusing on these topics, students can gain a deeper understanding of the subject matter and excel in biology exams.
