The present book is for B.Sc(I) yr, strictly based on UGC Model syllabus for all Indian Universities. Each unit or chapter as the case may be is followed by various types of questions, such as very short, short, long answer questions, digrammatic questions and multiple choice questions, asked repeatedly questions have been included.

For B.Sc. and B.Sc(hons.) students of all Indian Universities & Also as per UGC Model Curriculum. The multicoloured figures and arrestingly natural photographs effectively complement the standard text matter. The target readers shall highly benefit by correlating the content with the muliticoloured figures and photographs The book has been further upgraded with addition of important questions: long, short, very short and multiple questions in all chapters. A complete comprehensive source for the subject matter of various university examinations.

An outgrowth of more than three decades of classroom teaching experience, this book provides a comprehensive treatment of the subject. It comprises three parts; Inorganic, Organic and Physical Chemistry. Illustrations and diagrams are provided to help students in understanding the chemical structures and reactions. This book will meet the requirements of undergraduate students of B.Sc. First Year of all Indian universities.

This book has been combined for both the semester/terms and prepared keeping in view the the detail understanding of each topics.it is hope that our prospective technocrats,doctors ,research scholars will go through this edition and will appreciate the efforts put into bringing out the book.it is hoped that this book will be able to create interest in subject and also motivate the students for various competitive examinations.being fully aware of the level of the students for whom the book is written ,an effort has been made to use the simplest possible language It deals with the nuclear cytology,introducing students to various aspects of mitosis,meiosis,chromosome structure and changes .This study along with the study of genetics gives the student an idea of raw material of evolution.bio-geography and paleontology are the two important facts of the life which a student is made to understand past and present distribution of animals and also understand the importance of evidences supporting the idea of evolution.It is the consequence of the following factors:the potential for a species to increase its numbers,the genetic variability of offspring due to mutation and recombination of genes,a finite supply of the resources required for life and the selection by the environment of those offspring better able to survive and leave offspring.

For Degree, Honours and Postgraduate Students
