Taxonomy and Classification
Scientific Method
Cells, Molecules, and Biological Structure
100
These two domains consist entirely of prokaryotic organisms. 

Bacteria and Archaea

100

These multicellular organisms are producers that store sugars as starch. 

Kingdom Plantae

100
This is the broadest category in the taxonomic hierarchy. 

Domain

100

This step involves observing the world to form a question. 

Making an observation
100

A prokaryotic cell lacks these two major structural feature. 

Membrane-bound organelles and a nucleus

200

This domain contains organisms with membrane-bound organelles and nuclei. 

Eukarya

200

These organisms are consumers that ingest food and store sugars as glycogen. 

Kingdom Animalia

200

The two parts of a scientific name are…

Genus and specific epithet

200

This type of reasoning is used in predictions: “If X is true, then Y will occur.”

Deductive reasoning

200

These four macromolecules are fundamental to life: carbohydrates, proteins, lipids, and this. 

Nucleic acids

300

Members of this domain include extremophiles such as thermophiles and halophiles. 

Archaea

300

This kingdom contains decomposers that absorb nutrients and may be single or multicellular. 

Kingdom Fungi

300

The hierarchical order from phylum to species begins with this level. 

Class

300

These variables are placed on the x-axis and are manipulated during an experiment. 

Independent variables

300

This is the fundamental structural and functional unit of life. 

The cell

400

Organisms in this domain are all single-celled prokaryotes but are not typically extremophiles. 

Bacteria

400

This diverse group includes producers, consumers, and decomposers, but does not qualify as a kingdom. 

Protists

400

Linnaeus is famous for popularizing this naming system. 

Binomial nomenclature

400

Experimental results must be compared to this group, which lacks the independent variable. 

Control group

400
These structure form when atoms chemically bond. 
Molecules
500

This domain includes both unicellular and multicellular organisms like animals, plants, fungi, and protists. 

Eukarya

500

Plant cells contain this structural carbohydrates that forms their rigid cell walls. 

Cellulose
500

Taxonomy combined with evolutionary relationships forms this field. 

Systematics
500

A hypothesis becomes this only after significant evidence and scientific acceptance. 

A scientific theory
500

Organ systems combine to form this level of organization, which can contain trillions of cells.
