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). ESSENTIAL QUESTION: How do scientists classify all living organisms?
______
______
______
______
______To study all of the organisms on Earth, biologists have devised ways of naming and classifying them according to their similarities in structures.
The study of how scientists classify organisms is known as ______. The modern classification system uses a series of levels to ______organisms. An organism is placed first into a ______group and is then placed into more ______groups based its structures. The levels of classification, from broadest to most specific, include:______, ______, ______, ______, ______, ______, and ______. The more classification levels an organism shares with another, the more ______they have in common. Kingdom While scientists currently disagree as to how many kingdoms there are, most support a ______kingdom (Plants, Animals, Fungi, Protists, Monerans) system. Organisms are placed into kingdoms based on their ability to ______and the number of ______in their body. Phylum (pl. phyla) In the Plant Kingdom, phyla are sometimes referred to as______. Plants are normally divided into two groups: ______and ______. In the Animal Kingdom, there are many different phyla. These phyla can be divided into two groups: ______and ______. Class, Order, Family These levels become even more specific and will include fewer ______that have more in common with each other as they move down the levels. 1 STUDENT REVIEW: Characteristics of Organisms & Classification 6-2 The student will demonstrate an understanding of structures, processes, and responses of … organisms.

Genus (pl. Genera) Contains closely ______organisms. The genus is used as the ______word in an organism’s scientific name. Species Consists of all the organisms of the same type which are able to ______and produce young of the same kind. The species is used as the ______word in an organism’s scientific name.
Scientific name The scientific name of an organism is made up of its ______and ______. It is written in italics (Genus species) with the ______capitalized. For example, Canis lupus is the scientific name for the wolf; Pinus taeda is the scientific name for a loblolly pine.
Questions to consider: What does “taxonomy” mean?
What is the order for the levels of classification of organisms?
As organisms have more levels in common, what happens to their characteristics?
What are the two phyla/divisions for plants? … the two phyla for animals?
What is the largest level of classification with the greatest number of organisms?
As the level of classification becomes more specific, what happens to the number of organisms at that level?

Which two classification levels are parts of an organism’s scientific name?
What are the classification levels in the scientific name Panthera leo?
