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 ...
Biology Wax models showing the development of the rabbit heart Evolution. Because the rabbit's epiglottis is engaged over the soft palate except when swallowing, the rabbit is an obligate nasal breather. Rabbits have two sets of incisor teeth, one behind the other. This way they can be distinguished from rodents, with which they are often confused.
Oxford Dictionary of Biology (often abbreviated to ODB) is a multiple editions dictionary published by the English Oxford University Press. With more than 5,500 entries, [1] [2] it contains comprehensive information in English on topics relating to biology, biophysics, and biochemistry. [3] The first edition was published in 1985 as A Concise ...
The Catalogue of Life is an online database that provides an index of known species of animals, plants, fungi, and microorganisms. It was created in 2001 as a partnership between the global Species 2000 and the American Integrated Taxonomic Information System.

Ribulose 1,5-bisphosphate ( RuBP) is an organic substance that is involved in photosynthesis, notably as the principal CO2 acceptor in plants. [1] : 2 It is a colourless anion, a double phosphate ester of the ketopentose ( ketone -containing sugar with five carbon atoms) called ribulose.
Phyletic gradualism is a model of evolution which theorizes that most speciation is slow, uniform and gradual. [1] When evolution occurs in this mode, it is usually by the steady transformation of a whole species into a new one (through a process called anagenesis ). In this view no clear line of demarcation exists between an ancestral species ...
Ultrastructure (or ultra-structure) is the architecture of cells and biomaterials that is visible at higher magnifications than found on a standard optical light microscope. This traditionally meant the resolution and magnification range of a conventional transmission electron microscope (TEM) when viewing biological specimens such as cells ...
