Science Chapt. 17

Aristotle's System developed the first widely accepted system of biological classification; all organisms known into two groups: plants and animals. Subdivided in three groups: herbs, shrubs, and trees depending on the size and structure of the plant.
Classification grouping of objects or information based on similarities
Taxonomy branch of biology that groups and names organisms based on studies of their different characteristics
Linnaeus's System developed a method of grouping organisms that is still used by scientist today; based on physical and structural similarities of organisms
Binomial Nomenclature modern classification systems used a two-word naming system
Genus consist of a group of similar species
Specific Epithet second word which sometimes describes a characteristic
Family the next larger taxon in the biological classification system, consist of a group of similar genera.
Order taxon similar famlies
Class a taxon similar orders
Phylum a taxon of similar classes
Division plant taxonomists use this instead of using phylum
Kingdom taxon similar phyla or divisions
Archaebacteria prokaryotic and live in harsh environments such as deep sea vents and hot springs
Phylogeny evolutionary history of a species
Cladistics one biological system of classification that is based on phylogeny
Cladogram groups derived traits and use them to make a branching diagram
Eubacteria very strong cell walls and a less complex genetic makeup than found in archaebacteria
Protist Eukaryota that lacks complex organ systems and lives in moist environments
Fungus is either a unicellular or multi cellular Eukaryota that absorbs nutrients from organic materials from the environment
Prokaryote microscopic unicellular organisms that lack distinct nuclei bounded by a membrane
Eukaryote unicellular or multi cellular organisms such as yeast, plants, and animals composed Eukaryota cells, which contain a true nucleus and membrane-bound organelles
Plants multi cellular oxygen producers
Animals multi cellular heterotrophs
