Warm-Up

1. Warm-Up Label the groups used to classify organisms from least specific to most specific. Use the word bank to complete the diagram. class genus order species family kingdom phylum 1. 2. 3. 4. 5. 6. 7.

2. Classification (Taxonomy) of Organisms 6-2.2 Recognize the hierarchical structure of the classification (taxonomy) of organisms (including the seven major levels or categories of living things – kingdom, phylum, class, order, family, genus, and species).

3. To study all organisms on Earth, biologist have devised ways of naming and classifying them according to their similarities in structures.

4. Taxonomy – study of how scientists classify organisms. • Modern classification system uses a series of levels to group organisms. • An organism is placed into a broad group and is then placed into more specific groups based on its structures.

5. The levels of classification, from broadest to most specific, include: • Kingdom • Phylum • Class • Order • Family • Genus • Species (King Phillip Came Over For Great Spaghetti) • The more classification levels an organism shares with another, the more characteristics they have in common.

6. Kingdom • Most scientists support a five-kingdom system: • Plants • Animals • Fungi • Protists • Monerans

7. Organisms are placed into kingdoms based on their ability to make food and the number of cells in their body.

8. Phylum • In the Plant Kingdom, phyla are sometimes referred to as divisions. • Plants are normally divided into two groups: vascular and nonvascular. • In the Animal Kingdom, there are 35 different phyla. These phyla can be divided into two groups: vertebrates and invertebrates.

9. Class, Order, Family • These levels become even more specific and will include fewer organisms that have more in common with each other as they move down the levels.

10. Genus • Contains closely related organisms. • Genus = first word in an organism’s scientific name.

11. Species • Consists of all organisms of the same types which are able to breed and produce young of the same kind. • Species = second word in organism’s scientific name.

12. Scientific name • Made up of its genus and species. • Written in italics (Genus species) with the genus capitalized. • Example, • wolf = Canis lupus • loblolly pine = Pinustaeda

14. Classification Charts Directions: Use the given classification charts to answer the following questions. (Hint: Use the order of classification to answer each question) What is the order of classification of living things? ______________________ ______________________ ______________________ ______________________ ______________________ ______________________ ______________________ • Human • What is the family name of a human? ____________________ • What is the kingdom name of a human? ____________________ • What is the scientific name of a human? ____________________ • Gorilla • What is the order name of a gorilla? ____________________ • What is the genus name of a gorilla? ____________________ • What is the class name of a gorilla? ____________________ • House Cat • What is the phylum name of a house cat? ____________________ • What is the species name of a house cat? ____________________ • What is the scientific name of a house cat? __________________
