The study of the processes that enable animals and plants to grow and develop is referred to as developmental biology. It encompasses various fields of biology such as the biology of regeneration, asexual reproduction and metamorphosis. This field is also concerned with the growth of stem cells in adult organisms. It focuses on the main processes involved in the embryonic development of animals such as cell differentiation, regional specification, morphogenesis and growth. Cell differentiation refers to the formation of different functional cell types like muscle, secretory epithelia and nerve. This textbook is a valuable compilation of topics, ranging from the basic to the most complex theories and principles in the field of developmental biology. Some of the diverse topics covered herein address the varied branches that fall under this category. Those in search of information to further their knowledge will be greatly assisted by this book.
