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 ...
First, prefixes and suffixes, most of which are derived from ancient Greek or classical Latin, have a droppable vowel, usually -o-. As a general rule, this vowel almost always acts as a joint-stem to connect two consonantal roots (e.g. arthr- + -o- + -logy = arthrology ), but generally, the -o- is dropped when connecting to a vowel-stem (e.g ...
For example, the post-nominal elements in Japanese and Korean are sometimes called case particles and sometimes postpositions. Sometimes they are analyzed as two different groups because they have different characteristics (e.g., the ability to combine with focus particles), but in such analysis, it is unclear which words should fall into which ...

Many commonly named groups – rodents and insects, for example – are clades because, in each case, the group consists of a common ancestor with all its descendant branches. Rodents, for example, are a branch of mammals that split off after the end of the period when the clade Dinosauria stopped being the dominant terrestrial vertebrates 66 ...
When an ion channel opens and there is a net gain of positively charged ions, like sodium (Na +) and calcium (Ca 2+), that flow into the cell, this creates excitatory postsynaptic potentials (EPSP) that depolarize the cell membrane increasing the likelihood of an action potential by bringing the neuron's potential closer to its firing threshold ...
In biology, a taxon (back-formation from taxonomy; pl.: taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking , especially if and when it is accepted or becomes established.
