Developmental biology refers to the process of growth and development of plants and animals. It encompasses the biology and mechanisms of metamorphosis, asexual reproduction, stem cell growth and differentiation, and regeneration. Tissue patterning, tissue growth, and tissue morphogenesis are the chief processes related to the embryonic development of animals. Although plant development shares many similarities with animal development, plant morphogenesis is achieved via differential growth due to immotility of plant cells. Research in developmental biology emphasizes the use of model organisms. This book elucidates the concepts and innovative models around prospective developments with respect to developmental biology. It presents researches and studies performed by experts across the globe. This book is a resource guide for experts as well as students.
