19
Q

What is classification?

A

The process of grouping things based on their similarities

20
Q

What is taxonomy?

A

The scientific study of how organisms are classified

21
Q

What is binomial nomenclature?

A

Grouping organisms based on their observable features and giving them a 2 part name, the first being the genus and the second being the specific epithet

22
Q

What is a genus?

A

Classification grouping that contains similar, closely related organisms

23
Q

What is a species?

A

A unique group of similar organisms that can mate with each other and produce offspring that can also mate and reproduce

24
Q

What are the orders of classification?

A

Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species (does king phillip cook onion fried grape soup )

25
What is a taxonomic key?
A key that identifies different types of organisms
26
Why is a taxonomic key useful?
Because it helps identify different types of organisms
27
What are prokaryotes?
Unicellular organisms that lack a nucleus
28
What is a nucleus?
The dense area in the cell that contains nucleic acids and DNA
29
What are the 3 domains of life?
Archaea, Bacteria and Eukarya
30
What is the domain bacteria?
Unicellular organisms that can be in your body and can be either autotrophs or heterotrophs
31
What is the domain archaea?
Deep in the pacific ocean, live in harsh conditions that are unicellular and can be either autotrophs or heterotrophs
32
What are Eukaryotes?
Organisms whose cells contain a nucleus
33
What are the types of Eukaryotes?
Protists, animals, plants and fungi
34
What are the types of prokaryotes?
Archaea and Bacteria
35
What are protists?
Organisms in the Eukarya domain who can be either unicellular or multicellular, or autotrophs and heterotrophs (both/both)
36
What are fungi?
Organisms that can be unicellular or multicellular and call are heterotrophs (both/heterotrophs)
