Morphogenesis

International Series of Monographs on Pure and Applied Biology, Volume 2: Morphogenesis: The Analysis of Molluscan Development describes the various stages in molluscan morphogenesis. This book emerged from a series of lectures given for advanced biology students of the University of Utrecht. This book is composed of eight chapters and begins with a survey of the chemical processes going on in the egg cells during growth and vitellogenesis. The succeeding chapter considers the external factors affecting molluscan egg maturation and fertilization. Other chapters are devoted to other morphogenetic processes molluscan egg, including cell cleavage, gastrulation, germ layer formation, embryogenesis, and organogenesis. A chapter outlines the principal traits of molluscan development, as they emerge from the causal analysis developed in previous chapters. The concluding chapter discusses the further contributions to molluscan development. This book is of value to advanced biology teachers and students.
