Classification Study Guide Answers

Carolus Linnaeus is the scientist who is most well known for his work on classification and developed the binomial nomenclature system of naming organisms we use today. What two levels of classification are used for a species name according to binomial nomenclature? Genus and Species Prokaryotes are organisms that do NOT have a nucleus and Eukaryotes are organisms that DO have a nucleus. List the 7 levels of classification in order from broadest to most specific. Kingdom, phylum, class, order, family, genus, species

Which of the 7 classification levels is broader than the “order” level Which of the 7 classification levels is broader than the “order” level? Class Which of the 7 classification levels is more specific than the “order” level? Family Why do scientists organize living things into groups? So they are easier to study The most specific classification level is the Species and the most general (broadest) is the Kingdom

List the 6 kingdoms that all living things are grouped into List the 6 kingdoms that all living things are grouped into. Archaebateria, Eubacteria, protist, fungi, plants, animals The more levels of classification organisms share, the more they have in Common. A tool a scientist uses to classify living things is known as a Dichotomous Key.

Use the dichotomous key above to name this shape person. JoJo Draw a picture of Johnny below:

To create a dichotomous key, you must have Paired Statement at each level. An organism that cannot make its own food is called a/an Heterotroph and an organism that can make its own food is called a/an Autotroph. An organism that is composed of many cells is called Multicellular and an organism that is made of one cell is called Unicellular. Homo sapien is the scientific name for humans. What classification level did the word “Homo” come from? Genus What classification level did the word “sapien” come from? Species

A dog is a member of the kingdom Animal and a rose is a member of the kingdom Plant. The science of classification is called Taxonomy. According to the system developed by Linnaeus (binomial nomenclature), the name of any organism is made up of its Genus & Species. What is the main difference between archaebacteria and eubacteria? Archaebacteria is found in extreme locations. Eubacteria is found every where. What two kingdoms are made up of prokaryotes that do not have a nucleus. Archaebacteria and Eubacteria

Kingdom Archaebacteria Eubacteria Protist Fungi Plants Animals Type of Cell  Prokaryote prokaryote  eukaryote   eukaryote Number of Cells unicellular  unicellular most unicellular unicellular and multicellular Multicellular multicellular Cellular Structures cell wall, cell wall Some have cell wall and/or chloroplasts  Cell Wall NO cell wall Nutrition autotroph and heterotroph species  heterotroph  autotroph Reproduction asexual  asexual sexual, asexual sexual, asexual  sexual, asexual  mainly sexual

What would the grey wolf’s scientific name be? Canis lupus Which of the organisms in the table is least similar to the others? Explain. The Pine tree, because it belongs to the plant kingdom. Which of the organisms in the table is (are) most similar to a Lynx (Lynx rufus)? Explain. The grey wolf, because they share the most levels (kingdom, phylum, class, and order). What would the grey wolf’s scientific name be? Canis lupus Based on the information in the table, which two organisms would you say have the most similar evolutionary history? Explain.
