Beginning with a detailed introduction of the field of biology, this volume introduces readers to hundreds of important terms and concepts, including biodiversity, cell types, evolution, embryology, genetics, nutrient requirements, pollution effects, population growth, and much more. Entries include a complete discussion of the subject, related fields, key terms, plus illustrations, models and diagrams.
