Unit 7 NOTES: The Classification of Living Things Q: What is Classification? A: Putting things into groups, based on similar Taxonomy—the science of classifying living things. Somebody who does this for a living is called a taxonomist. Binomial System—Using the Genus and the species name to classify an organism. Ex: Homo sapiens = *Note: The Genus name is capitalized, the species name is lower-case. Order of Classification: Mnemonic Kingdom Phylum Class Order Family Genus Species Kingdom—Definition: The most general classification group. There are only 5 kingdoms on the planet. This means that all organisms on earth fall into one of those 5 kingdoms. Organisms in this group may not be very closely related to each other. For example, humans and flies are both in the animal kingdom, but they aren’t very closely related. Phylum—A group of closely related classes. Class—A group of closely related orders. Order—A group of closely related families Family—A group of closely related Genus—A group of closely related Organisms in the same genus are VERY closely related but not quite the same organism. Species—The most specific classification level. If 2 organisms are the same species, they are the same organism! The 5 Kingdoms of living things. 1. 2. 3. 4. 5. Monera (Bacteria) Fungi Plantae Protista Animalia 1. Monera—(Bacteria) A. Unicellular— B. Prokaryotic— C. Most are Heterotrophs— D. Reproduce asexually E. Examples: F. Importance: Mnemonic: 2. Fungi (fungus) A. Most are multicellular B. Eukaryotic— C. Heterotrophs D. Reproduce asexually E. Examples: F. Importance: 3. Plantae (plants) A. Multicellular B. Eukaryotic C. Autotrophs— D. Examples: E. Some reproduce sexually (flowers), but others reproduce asexually E: Importance 4. Protista (protists) A. Most are unicellular B. Eukaryotic C. Most are Heterotrophs (exception: algae) D. Examples: E. Importance: 5. Animalia (animals) A. Multicellular B. Eukaryotic C. Heterotrophs D. MOST reproduce sexually. Which ones don’t? E. Examples: F. Importance: Dichotomous keys: A listing of statements that allow you to identify an organism by its name. It uses observable characteristics to identify the name of the organism. Example: Taxonomy of humans Kingdom— Phylum— Class— Order— Family— Genus— Species— Taxonomy of the lion Kingdom— Phylum— Class— Order— Family— Genus— Species— Vocabulary Words for Unit 7 Dichotomous key Taxonomy Kingdom Family Binomial System Autotrophs Genus Classification Heterotrophs Phylum Species Monera Fungi Protista Animalia Plantae Order Class Chordata
