Taxonomy and Cladogr

Who is known as the father of taxonomy? Carolus Linnaeus
A systematic process of classifying living organisms into different groups based on their physical traits and genetic relationships. Taxonomy
The highest and broadest level of classification Domain
What is the order of the levels of classification? Domain-Kingdom-Phylum-Class-Order-Family-Genus-Species
Organisms are commonly referred to according to the two most specific taxonomic levels: genus and species, which are often Latin. This is called-- Binomial nomenclature
What is the taxonomic name of modern humans? Homo sapiens
T or F: The genus is always capitalized, the species is lowercase, and the whole name is written in italics. True
Scientists who study taxonomy and use the classification system to identify and name organisms. Taxonomists
Taxonomists often have advanced degrees in- zoology, animal physiology, botany, or other related fields.
What are the three domains? Bacteria, Archaea, and Eukarya
T or F: The domains differ fundamentally in their cellular structures and genetic makeup. True
Which domains consist of unicellular prokaryotes that are surrounded by a thick cell wall? Domain Bacteria and Domain Archaea
T or F: Bacteria can be found barely anywhere on Earth, and they are poorly diverse. False
T or F: Most bacteria are beneficial and serve a necessary role in their environment. True
How are the domains or Bacteria and Archaea different? The cell walls of Archaea are composed differently from the cell walls of Bacteria.
Which domain is able to survive in some of the most extreme environments of the Earth? Domain Archaea
Which domain's cells contain a nucleus and membrane bound organelles? Domain Eukarya
T or F: Most eukaryotic species are unicellular. False
Which domain contains the most well-known organisms? Domain Eukarya
How many kingdoms does domain Eukarya consists of? Four
Name the kingdoms. Protista, Plantae, Fungi, and Animalia
Many protistas are- unicellular
Examples of protists- phytoplankton, red and brown algae, and dinoflagellates.
Plants are multicellular organisms that are able to photosynthesize
The Plantae kingdom consists of- plants
What differentiates fungi from plants? Fungi have a cell wall, which is usually made of chitin instead of cellulose, and they cannot photosynthesize; they are heterotrophs.
A primary difference that differs fungi from other eukaryotes is that fungi grow long filaments called- hyphae
T or F: Animals are multicellular, are heterotrophic, and have cells lacking a cell wall. True
T or F: Animals vary little in their body plans, reproduction, methods for obtaining food, and many other factors. False
Which kingdom are humans a part of? Animalia
A branched diagram resembling a tree that shows the evolutionary relationship among organisms. Cladogram
Nodes Places where a lineage branches off in a cladogram
What is the purpose of a cladogram? To show how similarities between organisms are derived from common ancestry
What do nodes represent? Speciation events
T or F: The more the number of nodes between organisms, the more closely they are related. False
Why are cladograms so useful? They provide scientists with a visual summary of how organisms in any taxonomic grouping are related.
