Picture vocab

Binomial Nomenclature The system of naming organisms scientifically, developed by carolus Linnaeus; consists of the genus and species names.
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 The taxonomic level below the family and above the species; the first part of the binomial nominclature
Species A group of organisms that can interbreed to generate fertile offspring.
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 The lineage of successive parents and offspring that leads to an organism or species.
Cladistics A classification system based on shared characteristics between groups of organisms and their common ancestor.
unicellular Composed of a single cell
Multicellular Composed of more than one cell
Heterotrophic An organism that must consume other organisms for energy
Autotrophic An organism that obtains its energy from an abiotic source such as sunlight or inorganic chemicals.
Chemotrophic An organism that can produce its own nourishment through the process of oxidizing inorganic compounds
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
Phylogeny The evolutionary development of a species
four kingdoms of eukaryotes Protista, plantae, fungi, and animalia
Protista Many are unicellular, classified in this kingdom because they do not fit others.
Plantae Plants, multicellular organism that are able to photosynthesize.
Fungi mostly Multicellular, cell wall, cannot photosynthesize.
Animalia Includes humans, multicellular, heterotrophic, no cell wall. Mobile at least some point in life.
Taxonomist Scientists who study taxonomy and use the classification system to identify and name organisms.
Domains Bacteria, archaea, Eukarya
Domain Bacteria unicellular prokaryotes nucleus/membrane bound organelles
Domain Eukarya Very diverse, divided into four kingdoms
Domain Archaea Unicellular prokaryotes, have a cell wall, but different in composition from bacteria, Lack peptidoglycan. able to survive in some of the most extreme places on Earth.
