About the Book

I take sincere pride in presenting Gateway to Science – Biology for Class 9, written strictly in accordance with the NCERT textbook and the latest rationalised syllabus and examination pattern prescribed by the Central Board of Secondary Education (CBSE), New Delhi. This book has been carefully crafted to cater to the academic needs of both students and teachers.

Biology, the study of living organisms and various life processes, plays a pivotal role in helping students understand the complexity and diversity of life. It is a fascinating subject that enables learners to view life from a holistic perspective, deepening their understanding of living beings and their interactions with the environment. When approached systematically—with activities such as drawing, labelling, writing detailed explanations, and conducting experiments—Biology can become an enjoyable and meaningful learning experience.
