About the Book

Botany is an integrative science both drawing from and contributing to various fields of knowledge. Plant physiology is the basic branch in botany hence it plays significant role almost in all related fields in botany, like agriculture, horticulture, plant breeding, tissue culture, biotechnology, genetics, medical botany, etc. Plant Physiology is the science which deals with the functions of cells, tissues, organs or the plant as a whole and includes the study of the vital activities of the plants like absorption of water and Minerals from soil, photosynthesis, respiration, nitrogen metabolism, growth, etc.

This book has been written for the benefit of students pursuing B.Sc. Botany. However, the book will also be beneficial for students pursuing other life science courses. All topics are covered in a systematic manner. The language used is simple and self explanatory. Neatly labeled diagrams, charts and graphs with explanation are provided for the benefit of students.
