The subdiscipline of botany which studies the functioning of plants is known as plant physiology. It aims to understand the fundamental processes which occur in plants, such as respiration, photosynthesis, photoperiodism, transpiration, nastic movements, hormone functions, etc. It studies all the chemical and physical processes of plants at a small as well as large scale. Phytochemistry is a broad area of study within plant physiology. It refers to the study of the chemicals derived from plants. These chemicals are known as phytochemicals. Plant development is another area which is focused in this discipline. It is concerned with the growth and development of plant structures like roots, buds, flowers, shoots and leaves. This book aims to shed light on some of the unexplored aspects of plant physiology and the recent researches in this field. Some of the diverse topics covered herein address the varied branches that fall under this category. For all readers who are interested in plant physiology and plant development, the case studies included in this book will serve as an excellent guide to develop a comprehensive understanding.
