Binomial Nomenclature The system of naming organisms scientifically, developed by Carolus Linnaeus; consists of the genus and species names.
The 3 domains Bacteria, Archaea, Eukarya
Kingdom The highest level of taxonomic classification beneath that of the three domains.
Phylum The taxonomic level below kingdom and above class.
Class The taxonomic level below phylum and above order.
Order The taxonomic level below class and above family.
Family The taxonomic level below order and above genus.
Genus Genus The taxonomic level below the family and above the species; the first part of the binomial nomenclature.
Cladogram A branching diagram representing a hypothesis about the evolutionary descent of groups of organisms from a common ancestor.
Dichotomous Key A tool used to classify an organism through a series of questions with only two possible answers.
Ancestry (ancestries) Ancestry (ancestries)
Unicellular Composed of a single cell.
Multicellular Composed of more than one cell.
Heterotrophic (heterotroph) An organism that must consume other organisms for energy.
Autotrophic (autotroph) An organism that obtains its energy from an abiotic source such as sunlight or inorganic chemicals.
Eukaryotic Cell A cell with a nucleus and membrane-bound organelles.
Prokaryotic Cell A cell lacking a nucleus or any other membrane-enclosed organelle.
Sexual Reproduction The reproductive process involving two parents whose genetic material is combined to produce a new organism different from themselves.
Asexual Reproduction A method of reproduction that requires only one parent and produces offspring identical to the parent.
Taxonomy systematic process of classifying living organisms into different groups based on their physical traits and genetic relationships
Classification means putting things into orderly groups based on how they are alike
Taxonomy The science of identifying, classifying and naming living things
Kingdoms are the largest, most general groups
Genus the level of classification above species, the largest group into which organisms in a family are divided
Species the most specific of the seven levels of classification in sexually reproducing organisms (can breed to make offspring)
Dichotomous Key A guide to help identify unknown organisms
Archaebacteria A classification kingdom made up of bacteria that live in extreme environments
Eubacteria A classification kingdom made up of ALL modern bacteria except archaebacteria
Protista A classification kingdom of one-celled or many-celled, simple organisms; made up of all eukaryotes that are not plants, animals or fungi.
Plantae A classification kingdom made up of plants - usually green and use the sun's energy to make sugar by photosynthesis
Fungi A classification kingdom made up of complex organisms that get food by breaking down dead matter (mushrooms)
Animalia A classification kingdom made up of complex many celled organisms (animals)
Eukaryotic cell single cell organism or many-cell oragnisms who have a nucleus
Prokaryotic Cell Do not have a nucleus. Example - bacteria all bacteria are single-celled organisms
DNA the hereditary material that controls all the activities of the cell
Organisms anything that can independently carry out life process
Autotroughs self feeders - photosynthesis examples: Plants, algae, bacteria
Heterotroph is an organism that is unable to produce its own food. All animals are heterotrophs.
genes a segment of DNA that carries hereditary traits from parents to offspring
