Term | Definition |
Binomial Nomenclature | a system of nomenclature in which each species of animal or plant receives a name of two terms of which the first identifies the genus to which it belongs and the second the species itself. |
Class | a taxonomic rank. Other well-known ranks in descending order of size are life, domain, kingdom, phylum, order, family, genus, and species, with class fitting between phylum and order. |
Embryological Relationshop | one of the ways to determine the degree of relatedness between organisms. Based on the embryological development of the organisms |
Eukaryotic Cell | eukaryotic cell Cell that possesses a nucleus and the other membranous organelles characteristic of complex cells |
Evolutionary Relationship | one of the ways to determine the degree of relatedness between organisms. Based on the degree of separation between organisms on a cladogram. |
Family | is one of the eight major taxonomic ranks; it is classified between order and genus. |
Genus | a taxonomic rank used in the biological classification of living and fossil organisms in biology. |
Homologous Structure | structures that have the same origin but different uses. Example, whale fin and front leg of a dog. |
Kingdom | a taxonomic category of the highest rank, grouping together all forms of life having certain fundamental characteristics in common |
Order | a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. |
Phylum | is a taxonomic rank below kingdom and above class. |
Prokaryotic Cell | Cell lacking a nucleus and the membranous organelles found in complex cells; bacteria, including cyanobacteria. |
Species | A group of closely related organisms that are very similar to each other and are usually capable of interbreeding and producing fertile offspring. |
Sub-Phylum | is a taxonomic rank below the rank of phylum. The taxonomic rank of 'subdivision' in fungi and plant taxonomy is equivalent to 'subphylum' in zoological taxonomy. |
Taxonomy/Taxon | is the science of defining groups of biological organisms on the basis of shared characteristics and giving names to those groups. |
