This textbook, Algae: Fundamentals, Diversity, and Applications, offers a detailed exploration of algal biology and its wide-ranging significance in nature and human enterprise. The book is structured into six well-defined chapters covering fundamental concepts, including algal morphology, reproduction, major algal groups, ecological roles, and applied aspects of phycology. Beginning with a historical and taxonomic introduction, the book guides readers through cellular and thallus structures, pigment systems, reproductive strategies, and life cycles. A major focus is placed on the diversity of algal groups such as Chlorophyta, Rhodophyta, Phaeophyta, Cyanophyta, and Diatoms-each discussed with clarity and academic depth. The environmental chapter delves into algal habitats, blooms, eutrophication, and their ecological impacts. The final chapter highlights applied phycology, addressing algae's utility in biofertilisers, wastewater treatment, food, pharmaceuticals, and biofuels, along with emerging research directions. Designed primarily for university-level students in botany, microbiology, biotechnology, and environmental sciences, this book balances theory with application. It incorporates illustrations, key point summaries, and review questions to enhance comprehension and retention. Whether you are a learner seeking clarity, a teacher designing a syllabus, or a researcher exploring algal technologies, this book serves as a timely and informative resource. With the growing relevance of algae in global sustainability and biotechnology, this text bridges. foundational science and future innovation.
