Classification

Question 1

Classification

Answer 1

process by which scientists group living organisms

Question 2

Taxonomy

Answer 2

is the science of defining and naming groups of biological organisms on the basis of shared characteristics.

Question 3

Binomial nomenclature

Answer 3

system of nomenclature in which each species of animal or plant receives a name of two terms of which the first identifies the genus to which it belongs and the second the species itself.

Question 4

Taxon

Answer 4

a taxonomic group of any rank, such as a species, family, or class.

Question 5

Genus

Answer 5

A taxonomic category ranking used in biological classification that is below a family and above a species level, and includes group(s) of species that are structurally similar

Question 6

Family

Answer 6

is one of the eight major taxonomic ranks; it is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks above the rank of genus.

Question 7

Order

Answer 7

taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. Other well-known ranks are life, domain, kingdom, phylum, class, family, genus, and species, with order fitting in between class and family.

Question 8

Class

Answer 8

a taxonomic rank. descending order of size are life, domain, kingdom, phylum, order, family, genus, and species, with class fitting between phylum and order.

Question 9

Phylum

Answer 9

A group of Classes with similar distinctive characteristics

Question 10

Division

Answer 10

division refers to a rank equivalent to phylum.

Question 11

Kingdom

Answer 11

The highest classification into which living organisms are grouped

Question 12

Domain

Answer 12

also superkingdom or empire, is the highest taxonomic rank of organisms

Question 13

Phylogeny

Answer 13

The evolutionary development and history of a species or higher taxonomic grouping of organisms

Question 14

Characters

Answer 14

any observable feature, or trait, of an organism, whether acquired or inherited.

Question 15

Molecular clock

Answer 15

is a technique that uses the mutation rate of biomolecules to deduce the time in prehistory when two or more life forms diverged

Question 16

Cladistics

Answer 16

A system of classification based on the phylogenetic relationships and evolutionary history of groups of organisms, rather than purely on shared features

Question 17

Cladogram

Answer 17

a branching diagram showing the cladistic relationship between a number of species.

Question 18

Archaea

Answer 18

Any of the unicellular microorganisms that is genetically distinct from bacteria and eukaryotes, and often inhabiting extreme environmental conditions

Question 19

Protists

Answer 19

eukaryotic organisms that cannot be classified as a plant, animal, or fungus

Question 20

Fungus

Answer 20

molds, mildews, mushrooms, rusts, and smuts, that are parasites on living organisms or that feed upon dead organic material
