Why do biologists classify organisms? |
To organize and keep track of the enormous variety of life forms, to better understand evolutionary distances, and to examine the relationships between organisms. |
|
What is the difference between classification and taxonomy? |
Taxonomy is the classification of something, especially organisms. And classification is classifying something according to shared qualities or characteristics. |
|
Why do we use scientific names instead of common ones? |
Cause they are not specific to a particular species. |
|
How do you write a scientific name? |
In italics, next to the non-scientific name. |
|
Why do we use latin? |
So that communication and collaboration is possible, even though it’s a dead language. It’s also not changing and is the root for many languages. |
|
What are the major classification levels? |
Kingdom, Phylum, Class, Order, Family, Genus, Species |
|
What levels make up the scientific name? |
Binomial Nomenclature, also Genus and Species. |
|
List the 3 domains and 6 kingdoms. |
D: Archaea, Bacteria, and Eukarya K: Eubacteria, Archaebacteria, Protista, Animalia, Plantae, and Fungi |
|
Several genuses make up a _________. Several families make up _______. Several __________ make up a class. Several classes make up a ___________, and several phyla make up a __________. |
Family, orders, orders, phylum, kingdom. |
|
What’s the relationship between classification levels and relatedness? |
It tells the relationships and connectedness of the species or organism you are trying to identify. |
|
What are the 3 characteristics used to put organisms into the 3 domains? |
If its Eukaryotic, or Prokaryotic or if it is multicellular or unicellular. |
|
What characteristics of each of the 6 kingdoms? (List them and study them!!!) |
Animalia: Multicellular, Eukaryotic, Heterotrophic Plantae: Multicellular, Eukaryotic, Autotrophic Fungi: Multicellular, Eukaryotic, Heterotrophic Protista: Both Multi and Uni, Eukaryotic and Both Auto and Hetero Archaebacteria: Unicellular, Prokaryotic, both Auto and Hetero Eubacteria: Unicellular, Prokaryotic, both Auto and Hetero |
|
How did Aristotle and Linnaeus help with classification? |
Aristotle: grouped organisms into Plant or Animal.He then subdivided animals into water, land, or air dwellers. Linnaeus: developed system of classification into seven categories, each group more specific than the last |
|
What is a dichotomous Key? |
a tool that allows the user to determine the identity of items in the natural world, such as trees, wildflowers, mammals, reptiles, rocks, and fish. |
|
Why is a dichotomous Key helpful? |
Because they help you identify what the species is. |
|
What is a phylogenetic tree? |
a branching diagram or "tree" showing the inferred evolutionary relationships among various biological species or other entities—their phylogeny—based upon similarities and differences in their physical or genetic characteristics. |
|
When classifying organisms is appearance more important or evolutionary relationship? Why? |
Yes, because it shows the genes and traits that will be passed down the generation. |
|
Autotroph? |
make it’s own food. |
|
Binomial nomenclature? |
when each organism is given a specific name based on their genus and species |
|
Cilia? |
slender, microscopic, hair-like structures or organelles that extend from the surface of nearly all mammalian cells (multiple or single). |
|
Classification? |
classifying something according to shared qualities or characteristics. |
|
Eukaryote? |
a type of cell that contains a nucleus. |
|
Flagella? |
a whip-like structure that allows a cell to move. They are found in all three domains of the living world: bacteria, archaea, and eukarya |
|
Heterotroph? |
organism that is not able to make it’s own food. |
|
Homeostasis? |
the tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes |
|
Linnaeus? |
he developed system of classification into seven categories, each group more specific than the last |
|
Multicellular? |
Cell organization in an organism that have more than one cell. |
|
Nucleus? |
the home of the cell. |
|
Prokaryote? |
a type of cell that does not contain a nucleus |
|
Species? |
a large group of organisms. |
|
Taxonomy? |
the classification of something, especially organisms. |
|
Unicellular? |
Cell organization in an organism that have one cell.
