Classifications

Question 1

What is classification?

Answer 1

Grouping things according to characteristics. This science of this is known as taxonomy

Question 2

What is binomial nomenclature?

Answer 2

A two name classification system divided by genus (capitalized) and species (lower case). Scientific names are italicized or underlined.
This system has levels, each level is called a taxon. They get more specific the further down you go.

Question 3

Who developed Binomial Nomenclature?

Answer 3

Linnaeus

Question 4

What are the 7 classification groups?

Answer 4

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

Question 5

What is a phylogenetic tree?

Answer 5

A tree diagram that shows the evolutionary relationship between organisms with a common ancestor

Question 6

What is a dichotomous key?

Answer 6

A key with a series of choices the physical characteristics of different organisms

Question 7

What are rules for creating dichotomous keys?

Answer 7

1. There has to be one less step than # of organisms
2. The last step should allow for the identification of the last two organisms

Question 8

What is Domain?

Answer 8

The most inclusive taxon. Archaea, Bacteria, Eukarya

Question 9

What are the traits of Archaea?

Answer 9

-Similar to bacteria in structure but Eukarya in evolution
-Unicellular
-No nucleus (prokaryotic)
-No distinct organelles
-No peptidoglycan on the cell walls
-Extremophiles
Kingdom: Archaebacteria

Question 10

What are the traits of bacteria?

Answer 10

-Unicellular
-No nucleus
-No distinct organelles (Prokaryotic)
-Rigid cell wall of peptidoglycan
-Autotrophs and heterotrophs (Photosynthesis and consumption of food)
-Found in all habitats except where Archaea lives
-Antibiotics and diseases
Kingdom: Eubacteria

Question 11

What are the traits of Eurakarya

Answer 11

Divided into 4 kingdoms. Eukaryotic (have a nucleus and distinct organelles)

Question 12

What are the four kingdoms of Eurakarya?

Answer 12

Protista, Fungi, Plantae and Animilia

Question 13

What are the traits of Protista?

Answer 13

-Most unicellular. Some multicellular
-Some autotrophs. Some heterotrophs.
-Aquatic
-Some have animal characteristics. Some have plant characteristics. Some have fungi characteristics.

Question 14

What are the traits of Fungi?

Answer 14

-Multicellular (except yeast)
-Absorbive heterotrophs (digest food outside the body, then absorb it)
-Cell wall made of chitin

Question 15

What are the traits of Plantae?

Answer 15

-Multicellular
-Autotrophic
-Absorb sunlight to make glucose
-Cell wall made of cellulose

Question 16

What are the traits of Animalia?

Answer 16

-Multicellular
-Ingestive heterotrophs
-Feeds on plants and animals
