Biology Vocabulary and Classification

First things first! Some important vocabulary: compare and contrast a prokaryote cell with an eukaryote cell.

• Prokaryote cells have no nucleus, while eukaryote cells have a nucleus.

• Prokaryote cells have a nucleus, while eukaryote cells have no nucleus.

• Both prokaryote and eukaryote cells have a nucleus.

• Neither prokaryote nor eukaryote cells have a nucleus.

Important vocabulary continued: Which of the following organisms produces its own food?

• Autotroph

• Heterotroph

Important vocabulary continued: what is the difference between a unicellular organism and a multicellular organism?

• A unicellular organism consists of a single cell, while a multicellular organism consists of multiple cells.

• A unicellular organism has multiple cells, while a multicellular organism has a single cell.

• Both unicellular and multicellular organisms consist of multiple cells.

• Both unicellular and multicellular organisms consist of a single cell.

Classification is often changing! After introducing the domains, this video shows a 5 kingdom and 6 kingdom system. Why is classification subject to change?

• New discoveries and advancements in science

• Changes in political boundaries

• Economic factors

• Cultural influences

Which of the following shows all taxonomic levels from most inclusive to least inclusive?

• Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species

• Kingdom, Domain, Phylum, Class, Order, Family, Genus, Species

• Phylum, Kingdom, Domain, Class, Order, Family, Genus, Species

• Class, Phylum, Kingdom, Domain, Order, Family, Genus, Species

What is the benefit of a scientific name vs. a common name?

• Scientific names are universally recognized.

• Common names are more descriptive.

• Scientific names are easier to remember.

• Common names are used in scientific literature.

The video explains the two parts of a scientific name in binomial nomenclature. Which of the following labels the parts of this scientific name correctly?

• Genus and Species

• Family and Genus

• Order and Family

• Species and Order

In the video, two different domains of prokaryotes were discussed. In a six kingdom system, these prokaryotes can also make up two of the six kingdoms. Which are these two separate prokaryote groups?

• Archaea and Bacteria

• Protista and Fungi

• Plantae and Animalia

• Eukarya and Archaea

In the video, the domain Eukarya includes all eukaryote organisms. In a six kingdom system, these eukaryotes can make up four of the six kingdoms. Which of the following are these separate eukaryotic kingdoms?

• Animalia, Plantae, Fungi, Protista

• Bacteria, Archaea, Animalia, Plantae

• Fungi, Protista, Bacteria, Archaea

• Animalia, Plantae, Bacteria, Archaea
