The present book entitled "A Text book of Botany: Diversity of Microbes" has been written with the feeling that it will usefully serve the purpose of B.Sc. students. Basic as well as modern views are considered. Informative & understandable diagrams have been incorporated in this book. The content is very simple. In preparation of book many books & papers have been consulted. I hope that this book will continue to serve its purpose in understanding the basic principles of Botany & securing at the same time maximum marks in examination by the students.

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.
