Plants are crucial for the sustainment of life on Earth. They provide the necessary oxygen and food, as well as medicine and other products. They are essential for binding and stabilizing soils, preventing soil erosion, and balancing carbon and water cycles. The branch of biology concerned with the study of plants including their structure, biochemical processes and properties is known as botany. It also encompasses plant physiology and pathology, plant classification and their interactions with the environment. The foundation of many applied sciences such as forestry, agriculture and horticulture is built on the principles and applications of botany. Modern botany is a multidisciplinary subject that integrates many different areas of science and technology. The study and investigation of plant growth and differentiation, structure, biochemistry, evolution, systematics, etc. are significant areas of research in this discipline. The field of botany has undergone rapid development over the past few decades. This book brings forth some of the most innovative concepts and elucidates the unexplored aspects of this area of study. Coherent flow of topics, student-friendly language and extensive use of examples make this book an invaluable source of knowledge.
