Survey of Biological Progress, Volume II is an eight-chapter text that covers the advances in some biological subjects, including human genetics, plant morphogenesis, histochemistry, and plant reproduction. The opening chapter examines the kinetics of the effect of radiation on living systems. The succeeding chapters explore the developments in the field of human genetics and oceanography. These topics are followed by discussions on the regularity and the specific patterns exhibited in plant morphogenesis; the practical application of plant hormones in horticulture and agriculture; and the technical problems in histochemical studies. A chapter evaluates theoretical and experimental evidence on the fine structure of protoplasm. The final chapter looks into the environmental factors and physiological changes that can be associated with the production of sex structures of all kinds of plants. This book is of great value to biologists, geneticists, researchers, and biology teachers and students.
