About the Book

Biology is the study of life and living organisms. In recent years, the focus of biology has gradually shifted from the structure of living organisms to understanding how they function and interact with their environment. This transformation in biological sciences has opened new avenues of knowledge and raised thought-provoking questions. The present book aims to help students understand and contribute meaningfully to this ongoing biological revolution.

This edition has been thoroughly revised and updated in accordance with the latest Biology syllabus prescribed by the Council for the Indian School Certificate Examinations (CISCE), New Delhi, for the Indian Certificate of Secondary Education (I.C.S.E.) Examinations.
