| What are 2 features of biological classification systems used in taxonomy? | 1) a universally accepted name is assigned to each organism; 2) the systems place organisms in groups that have real biological meaning. |
| What is true of organisms that are placed in a particular group? | They are more similar to each other than they are to organisms in other groups. |
| What did early scientific names describe? | Latin or Greek words described the physical characteristics of a species, creating names that might be 20 words long. |
| What drawbacks did early classification systems have? | 1) very long names; 2) one organism might have different names (scientists described different characteristics of the same species). |
| What was the system developed by Carolus Linnaeus called? | binomial nomenclature |
| What do the two names under Linnaeus' system specify? | 1) the genus name; 2) the species name |
| What is the proper way to write the Latin name of an organism? | 1) capitalize the genus name 2) do not capitalize the species name 3) the entire name is in italics |
| What are the advantages of binomial nomenclature? | 1) once a scientific name has been chosen, it is used consistently; 2) a specimen of each species is on file for reference; 3) scientists can compare their "finds" with the file to see if a new species has been discovered. |
| What are the 7 original classification groups? (from largest to smallest) | kingdom, phylum, class, order, family, genus, species. See the examples on pg. 449 & 450. |
| Make up a mnemonic to help you remember the original 7 classification groups. | Example: King Phillip came out for grapes Sunday. (each 1st letter stands for a classification group: K=kingdom; P=phylum, etc.). |
| What were the 2 kingdoms in Linnaeus' system? | Animalia and Plantae were the 2 kingdoms. |
