This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
Anatomical terms are not included here and appear in sub-categories of the main Anatomy category. Initially, some alignment between this category and the article Glossary of biology was considered, but the inclusion criteria for the Glossary is substantially broader and encompasses terminology, concepts, objects and processes.
