About the Book

Plant Physiology is the science that attempts to explain all plant processes. It is the science that explains how plants work. Plant Physiology includes the study of all the internal activities of plants, all the chemical and physical processes as they occur in life of plants. This study is very important to students of Botany.

Neat labeled diagrams, tables, charts and illustrations, tabular classifications are included which will help students in better understanding of the subject.

Topics are explained in a simple style and are explanatory. Diagrams and illustrations are neatly labeled and explained for students to understand the concepts well. Exercise questions and Past University questions are included for each chapter which will help students in preparing from examination point of view.
