Study Guide Topic # 0001A Nomenclature Definition - Giving and using of names. - Code for something of importance - Codes things we will want to remember and use again Grouping and arrangement of organisms into a hierarchical order Arrangement of organism resulting from classification procedures Important aspect of classifications is their predictive value Challenges of classification Greek scientist who tried to classify living things Place all living things into two main groups - - Plants are green and do not move - Animals are not green and do move More Modern Classification Scientists used Aristotle's classification for hundreds of years More and more things were discovered - Aristotle's system became because more plants and animals were being found In the eighteenth century, a scientist named reworked the system of classification First divided all living things into two main groups as Aristotle had. - called - A is the first and largest division of living things Linnaeus continued to subdivide the kingdoms Called Size is not used in this grouping - Very specific traits based on appearance of certain parts are used Phyla Plural of phylum Can be divided into smaller groups, called Largest division of a phylum - Again divided into smaller groups Seven Divisions in Classification The science of classification and the arrangement of plants and animals into groups based on their natural relationships Five Kingdoms Kingdom (Animalia) - Includes invertebrates and vertebrates Kingdom (Plantae) Kingdom - Includes simple plants that lack chlorophyll Kingdom - Bacteria and blue-green algae Kingdom - Unicellular organisms with a true nucleus and chromosomes Nomenclature Established by Linnaeus about 1758 Each species is given a "scientific name" consisting of Latin words - The first (genus) is capitalized - The second (subdivision of genus) is not capitalized Binominal Nomenclature (example) Kingdom: Phylum: Class: Order: Family: Genus: Species: NOMENCLATURE Nomenclature Definition - Giving and using of names. - Code for something of importance - Codes things we will want to remember and use again Classification Grouping and arrangement of organisms into a hierarchical order Arrangement of organism resulting from classification procedures Important aspect of classifications is their predictive value Challenges of classification Not simple Wide variety of living things Specimens are not easy to find Aristotle Greek scientist who tried to classify living things Place all living things into two main groups - plants and animals - Plants are green and do not move - Animals are not green and do move More Modern Classification Scientists used Aristotle's classification for hundreds of years More and more things were discovered - Aristotle's system became less helpful because more plants and animals were being found In the eighteenth century, a scientist named Linneaus reworked the system of classification First divided all living things into two main groups as Aristotle had. - called kingdoms A kingdom is the first and largest division of living things - plants make up one kingdom - animals make up the other Linnaeus continued to subdivide the kingdoms Called phylum - Size is not used in this grouping - Very specific traits based on appearance of certain parts are used Phyla Plural of phylum Can be divided into smaller groups, called classes - Largest division of a phylum - Again divided into smaller groups Seven Divisions in Classification Kingdom Phylum Class Order Family Genus Species Taxonomy The science of classification and the arrangement of plants and animals into groups based on their natural relationships Five Kingdoms Animal Kingdom (Animalia) - Includes invertebrates and vertebrates Plant Kingdom (Plantae) Fungi Kingdom - Includes simple plants that lack chlorophyll Monera Kingdom - Bacteria and blue-green algae Protista Kingdom - Unicellular organisms with a true nucleus and chromosomes Binomial Nomenclature Established by Linnaeus about 1758 Each species is given a "scientific name" consisting of two Latin words - The first (genus) is capitalized - The second (subdivision of genus) is not capitalized Binominal Nomenclature (example using cattle) Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Artiodactyla Family: Bovidae Genus: Bos Species: Bos taurus and Bos indicus
