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 ...
Class (biology) The hierarchy of biological classification 's eight major taxonomic ranks. A phylum contains one or more classes. Intermediate minor rankings are not shown. In biological classification, class ( Latin: classis) is a taxonomic rank, as well as a taxonomic unit, a taxon, in that rank. It is a group of related taxonomic orders.
The Dewey Decimal Classification (DDC) is structured around ten main classes covering the entire world of knowledge; each main class is further structured into ten hierarchical divisions, each having ten divisions of increasing specificity. [1] As a system of library classification the DDC is "arranged by discipline, not subject", so a topic ...
Glossary of cellular and molecular biology (0–L) This glossary of cellular and molecular biology is a list of definitions of terms and concepts commonly used in the study of cell biology, molecular biology, and related disciplines, including genetics, biochemistry, and microbiology. [1] It is split across two articles:
In biology, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system of biological classification ( taxonomy) consists of species, genus, family, order, class, phylum, kingdom, and domain. While older approaches to taxonomic classification were phenomenological, forming ...
Simply, the study of internal structure of living organisms. Comparative anatomy – the study of evolution of species through similarities and differences in their anatomy. Osteology – study of bones. Osteomyoarthrology – the study of the movement apparatus, including bones, joints, ligaments and muscles. Viscerology – the study of organs.
